+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+\f
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+\f
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+\f
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+\f
+ Appendix: How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19yy name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+
+2001-10-16 Boszormenyi Zoltan <zboszor@externet.hu>
+
+ * ean.c:
+
+ I found that barcode-0.96 does not correctly encodes UPC-E.
+ This was mainly because in upc_e_to_a() the switch() branches
+ all ended without "break;".
+
+ Printing UPC-E did not print the leading encoding number and
+ the trailing UPC-A checksum. Now it does.
+
+ Accept EAN-13 and EAN-8 with and without the checksum.
+ So always treat 7 and 12 digit sequences as valid EAN codes
+ and accept 8 and 13 digit sequences as valid EAN codes when
+ the last digit is the same as the calculated one.
+
+ Accept UPC-A as above (11 or 12 digit sequences.)
+
+ Accepts UPC-E as:
+ 6 digit sequence: the middle part of the code (leading '0' assumed)
+ 7 digit sequence: the middle part and either a leading '0' or '1',
+ or a trailing UPC-A checksum. In that case, leading '0' assumed.
+ 8 digit sequence: a leading '0' or '1', middle part, checksum
+
+ UPC-A, UPC-E, EAN-13, and EAN-8 may all include
+ an additional barcode to the right of the main barcode.
+
+ As a 7 or a 12 digit sequence may be ambiguous, please remember
+ that EAN is checked before UPC if you specified BARCODE_ANY.

+
+2000-04-21 Alessandro Rubini <rubini@morgana.systemy.it>
+
+ * doc/Makefile: modified to build with both gmake and pmake

+
+2000-04-09 Alessandro Rubini <rubini@morgana.systemy.it>
+
+ * code128.c (Barcode_128_encode): removed extra messages to stderr,

+
+Installing on generic Unix systems
+----------------------------------
+
+The package includes both a library and a standalone program.
+To install everything try
+
+ ./configure && make && make install
+
+To uninstall, try
+
+ make uninstall
+
+You may have problems compiling the package on non-GNUish systems,
+because the tool currently uses both gmake and gawk features, and I have
+no access to non-gnu systems. If your operating system isn't able to
+compile barcode and you are willing to help porting, feel free to call me.
+
+
+Installing on Debian/GNU systems
+--------------------------------
+
+The suggested installation here includes creation of a Debian package:
+
+ debian/rules binary
+
+Then, just install using dpkg:
+
+ dpkg -i ../barcode-0.98_*.deb
+
+(the "*" here will represent your architecture: "i386", "alpha", "sparc", ...)

+NETWORK LINKS
+=============
+
+This is GNU-barcode. The latest release can be downloaded from ftp.gnu.org
+and mirrors:
+ ftp://ftp.gnu.org/pub/gnu/barcode/
+
+It is also available from my own ftp/http server
+ ftp://ar.linux.it/pub/barcode/
+ http://ar.linux.it/pub/barcode/ (same as above).
+
+The current source tree is available by anonymous CVS. See
+ http://ar.linux.it/software/#cvs
+
+Plesae note that ar.linux.it/pub/barcode also includes CVS snapshots,
+semi-atumatically taken when I commit stuff to CVS. Note that CVS
+snapshots include "CVS/" directories, so you can then "cvs update" for
+further updates.
+
+The documentation is online at:
+ http://ar.linux.it/software/barcode
+
+The MS-Windows port is maintained at:
+ http://gnuwin32.sourceforge.net/packages/barcode.htm
+
+It as also been included in the FreeBSD ports tree in the "graphics" section.
+This means /usr/ports/graphics/barcode. It's thus available from:
+ http://www.freebsd.org/ports/graphics.html
+
+GLabels, at http://snaught.com/glabels/, uses barcode internally, too.
+
+DESCRIPTION
+===========
+
+The package is meant to solve most needs in barcode creation with a
+conventional printer. It can create printouts for the conventional
+product tagging standards: UPC-A, UPC-E, EAN-13, EAN-8, ISBN, as well
+as a few other formats. Ouput is generated as either Postscript or
+Encapsulated Postscript (other back-ends may be added if needed).
+
+The package is released as both a library and a command-line frontend,
+so that you can include barcode-generation into your application. The
+program is released in the hope that is proves useful but without any
+warranty, according to the GPL Licence (see ./COPYING).
+
+If you're specifically interested in making an ISBN (Bookland EAN)
+symbol, you might try to get "bookland.py" by Judah Milgram
+(http://www.cgpp.com/bookland/, whose version 0.92 is also included in
+the directory "bookland" within this package, for your convenience).
+While my main target is flexibility his main target is strict
+adherence to the standards. Bookland is free software like the barcode
+library and will probabily have its role in the GNU project.
+Bookland.py is a self-documenting program, you'll enjoy browsing its
+source code.
+
+Other contributed patches and/or software are available in the
+contrib/ directory.
+
+Please take the "no-warranty" disclaimer seriously: even though I
+spent reasonable efforts to make sure the output is useable in
+production you should verify it suits your needs as a faulty bar can
+cost you a bundle, and you'll be on your own. It's up to you to verify
+that the symbol is valid (and, obviously, I'd like to know about any
+problem you encounter). [This paragraph copied verbatim from bookland.py]
+
+
+ACKNOWLEDGMENTS
+===============
+
+I would like to thank both Judah Milgram and Michele Comitini
+(mcm@glisco.it) for their help with this tool, as well as Jim Westveer
+for introducing me to Debian packaging. Several encodings have been
+implemented by Leonid A. Broukhis (leob@mailcom.com).
+
+
+MAILING LISTS
+=============
+
+There is a mailing list where development is coordinated, called
+barcode@lists.linux.it . To get subscribed you should
+ echo subscribe | mail barcode-request@lists.linux.it
+or anything equivalent.
+
+To receive notification of CVS commit messages, please subscribe to
+barcode-commit@ar.linux.it, by issuing:
+ echo subscribe | mail barcode-commit-request@ar.linux.it
+
+(if you guess, "ar" or "arcana" is my own server, while lists.linux.it
+is the mail server of the italian association of gnu/linux users).
+
+/alessandro (rubini@gnu.org)
+
--- /dev/null
+
+ Possible enhancements that I'd like to add
+
+* verbose mode, printing position information to stderr
+
+* document how a new encoding standard can be added
+
+* add Barcode_String, which has been contributed
+
+* EAN128 (as agreed with Dani Pardo)
+
+* Postnet and associated encoding-specific bar definitions
+
+* Use texinfo 4 with images
+
+* shrink the bars to account for ink spreading
+
+ Currently, small barcodes don't get rendered well. While
+ version 0.91 and later subtracts 0.15 points from the size of
+ the bars (I found that this makes good results for small
+ bars), a smart alghorithm to shrink the bars is needed to get
+ lighter prints at small sizes without loosing readability.

+# usage: bookland.py [ISBN] [price-code] > output.eps
+#
+# ISBN - the ISBN, with or without check digit, with or without hyphens.
+# default: 1-56592-197-6 ("Programming Python"). If the check digit
+# is provided on the command line, it is verified. If not, it is
+# calculated. It's up to you to get the hyphenation right - it's
+# important, and something the program can't calculate for you.
+#
+# price - the five digit add-on code. Usually used to indicate the price,
+# in which case the first digit indicates the currency (4=$CAN,
+# 5=$US, etc.). The remaining digits indicate the price, with
+# decimal point assumed to be between the digit 3 and 4.
+# For example: $US 6.95 = 50695, $CAN 35.00 = 43500. Instead of a
+# price code, a 5 digit add-on ranging from 90000-98999 can be
+# used for internal purposes. BISG recommends just using 90000 if
+# you don't want to specify a price. Add-ons ranging from 99000 to
+# 99999 have been reserved for special use.
+#
+# An Encapsulated Postscript file (eps) is sent to standard out. This may in turn
+# be converted to other formats using the pbmplus package. You may have trouble
+# getting the OCRB to map correctly. If you already have the font, you can look in
+# the Fontmap file to see what your system calls it, and edit the fontnames accordingly
+# (see below). If you don't have it, you might find it on your DOS system. You
+# need a .pfa/.pfb (Type 1) or .ttf (TrueType). Your Postscript interpreter might
+# or might not be able to deal with TrueType. In any event, in an emergency, you
+# might get away with Helvetica. Note that as of 1990 BISG no longer requires the
+# ISBN to be printed in OCR-A.
+#
+# Take the "no-warranty" disclaimer seriously. Going to print with a faulty bar
+# can cost you a bundle, and you'll be on your own. It's up to you to verify that
+# the symbol is valid. If you need "corporate accountability", try the Book
+# Industry Study Group at (212) 929-1393 or the US ISBN Agency at (908) 665-6770
+# and ask for a list of commercial vendors. Outside the US, don't know.
+#
+# Feedback welcome. If you discover a case where the program generates a faulty
+# symbol, I definitely want to hear about it - write me at milgram@cgpp.com or

+#
+# ABOUT THE BOOKLAND EAN
+#
+# The most difficult part of this project was finding the documents that define
+# the Bookland EAN. There appears to be no single, authoritative source that
+# provides all the information required. Some good sources:
+#
+# [1] "Machine-Readable Coding Guidelines for the U.S. Book Industry", Book
+# Industry Study Group, New York, Jan., 1992. (212) 929-1393
+# [2] "UPC Symbol Specification Manual", Uniform Code Council Inc.,
+# Dayton, Ohio, January 1986 (May 1995 Reprint). (937) 435-3870; I found it
+# at http://www.uc-council.org/d36-t.htm
+# [3] "EAN Identification for Retail/Trade Items", EAN International. I found it
+# in Feb. 1999 at http://www.ean.be/html/Numbering.html
+# [4] "Hyphenation Instructions", web page at:
+# http://www.isbn.org/standards/home/isbn/international/hyphenation-instructions.asp
+#
+# The starting point of the exercise is the ISBN, assigned by the national ISBN
+# Agency. This is a 10 digit number, the last being a check digit. The ISBN is
+# converted to a 13 digit EAN number. The first three digits of the EAN-13 indicate
+# the country or region. A prefix of 978 has been assigned to books, regardless
+# of country of origin (hence, "Bookland") [3]. The remaining ten digits are the
+# first 9 digits of the ISBN followed by the EAN-13 check digit.
+#
+# It seems the EAN-13 check digit can be calculated using the same algorithm as the
+# UPC Version A number. Note that the EAN-13 check digit is always between 0 and 9,
+# compare with ISBN check digit which can range to 10 ("X"). See Reference [2],
+# Section 2 and Appendix G for details of creation of the EAN-13 symbol. Table 2 of
+# Appendix G provides a good comparison of the UPC-A and EAN-13 symbols.
+#
+# The 5 digit add-on (here called, "UPC5") is defined in Ref. [2] Appendix D.
+# The ">" to the right of the five digit code serves to enforce the "quiet zone" to
+# the right of the bar pattern. Can't remember where I read that. It's probably
+# optional. According to [1], in the UK, three horizontal bars appear over price
+# add-ons. Haven't implemented that here. The UPC5 encoding is based on UPC-A and
+# UPC-E.
+#
+# According to [2], Section 3, the EAN-13 numbers and 5-digit add-ons are supposed
+# to be printed in OCR-B. The ISBN itself is printed above the EAN-13 symbol. At
+# one time it was to be printed in OCR-A, but as of 1990 this requirement has been
+# dropped [1], and I assume this means you can use any font you like.
+#
+# SEE ALSO:
+#
+# "TinyHelp 5 - Making ISBN Barcodes", D. Byram-Wigfield. Another approach to making
+# the ISBN barcode symbol. I saw it at
+# http://www.cappella.demon.co.uk/index.html/
+# but haven't tried it.
+#
+# "XBarcode" - nice open-source X-Windows program for generating all sorts of bar codes.
+# It does much more than this program, but didn't seem to do the UPC
+# 5-digit add-on or do the ISBN->EAN13 calculation (as of v. 2.11). Might
+# have made more sense to add this capability, but I needed a Python project.
+# In any event, their license forbids distribution in modified form!
+#
+# HYPHENATION
+#
+# bookland.py includes automatic hyphenation for ISBN's in group 0 and 1
+# (English-language). This is based on my reading of Ref [4]. If in doubt,
+# users can use the "-y" option to force the program to accept the hyphenation
+# as input. For other ISBN groups and for ISMN's, no hyphenation is performed
+# other than to ensure a hyphen is placed after the group identifier and before
+# the check digit.
+#
+# ABOUT THE ISMN:
+#
+# See the ISMN Users' Manual, 3rd Edition, 1998, ISBN 3-88053-070-X, published by
+# the International ISMN Agency, Staatsbibliothek Preussischer Kulturbesitz, Berlin.
+# I found my copy at http://www.ismn.spk-berlin.de/download/ISMNmanual.pdf
+#
+# An ISMN is just like an ISBN, except:
+# - first character is an "M"
+# - the "M" counts as a "3" for computing the ISMN check digit (last digit)
+# - the checksum weights are 3,1,3,1,3,1,3,1,3, sum to be divisible by "10". This
+# means the last character is always a numerical digit, never an "X".
+# - the EAN number is "979" plus the *entire* ten character ISMN, except the
+# "M" is replaced by "0". Note this means the ISMN checksum is identical to the
+# corresponding EAN-13 checksum (excercise left to the reader).
+#
+# When bookland.py detects an "M" in the first position of the ISBN, it interprets
+# it as an ISMN and proceeds accordingly. The 5-digit price code symbol is suppressed.
+#
+# BAR WIDTH REDUCTIONS
+#
+# Starting Version 0.92, the widths of the individual bars can be reduced using the
+# "-r" option (units are inches). This is to compensate for bleed during printing.
+# I don't know when it's a good idea to actually use this; in any event consult with
+# your printer first. If not input, it defaults to zero (no reduction).
+#
+# ABOUT PYTHON
+#
+# See http://www.python.org
+#
+# TO DO:
+#
+# - Generalize to more bar codes, starting with UPC-A and UPC-E. "Plain" EAN13 is
+# already built in, could add command line argument to generate that instead of
+# Bookland.
+# - Make font sizes and placement easier to configure - not sure I have it right.
+# Does human-readable 5-digit code take wider font spacing?
+# - Clean up bounding box stuff.
+# - Bells and whistles.
+# - GUI?
+#
+# HISTORY:
+#
+# 1/2002 - v 0.92 add ISMN support (thanks to Lars-Henrik Nysten for this suggestion)
+# re-wrote bar generation to preclude possibility of white hairlines
+# between adjacent black modules. Thanks to Tero Lindfors for
+# reporting this bug.
+# new -o option to write eps to file rather than stdout
+# new -x option for "check only" (verifies check digit)
+# new -r option for bar width reduction (compensate for print bleed)
+# new -s option to scale module (bar) height (Lars-Henrik Nysten again)
+# can suppress UPC-5 price code by entering empty string. (thanks to
+# Jacques Du Pasquier for this suggestion)
+# re-wrote ISBN/ISMN sanity checks
+# lowercase alphas ("x" for ISBN and "m" for ISMN) now ok on input
+# fix "long" command line options.
+# 10/2001 - v 0.91 add -z option for quiet zone ">"
+# add -f option for fonts
+# re-write command line parsing to use getopt
+# 1/2000 - v 0.09 eliminate use of eval
+# 9/99 - v 0.08 accomodate different versions of OCRB by fitting
+# all strings to prescribed width. Thanks to Toby Gadd
+# for reporting this problem and Peter Deutsch for
+# help finding the fix.
+# 7/99 -v0.05-0.07 improve error handling.
+# 3/27/99 - v0.04 add "--help" and "--version".
+# 3/13/99 - v0.03, do a showpage at end (it's allowed)
+# fixed checksum calculations for certain cases
+# 2/7/99 - v0.02, fixed LH parity pattern for EAN13. It's not the check digit!
+# 2/7/99 - initial release

+
+ If an element of ARGV starts with '-', and is not exactly "-" or "--",
+ then it is an option element. The characters of this element
+ (aside from the initial '-') are option characters. If `getopt'
+ is called repeatedly, it returns successively each of the option characters
+ from each of the option elements.
+
+ If `getopt' finds another option character, it returns that character,
+ updating `optind' and `nextchar' so that the next call to `getopt' can
+ resume the scan with the following option character or ARGV-element.
+
+ If there are no more option characters, `getopt' returns `EOF'.
+ Then `optind' is the index in ARGV of the first ARGV-element
+ that is not an option. (The ARGV-elements have been permuted
+ so that those that are not options now come last.)
+
+ OPTSTRING is a string containing the legitimate option characters.
+ If an option character is seen that is not listed in OPTSTRING,
+ return '?' after printing an error message. If you set `opterr' to
+ zero, the error message is suppressed but we still return '?'.
+
+ If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+ so the following text in the same ARGV-element, or the text of the following
+ ARGV-element, is returned in `optarg'. Two colons mean an option that
+ wants an optional arg; if there is text in the current ARGV-element,
+ it is returned in `optarg', otherwise `optarg' is set to zero.
+
+ If OPTSTRING starts with `-' or `+', it requests different methods of
+ handling the non-option ARGV-elements.
+ See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+ Long-named options begin with `--' instead of `-'.
+ Their names may be abbreviated as long as the abbreviation is unique
+ or is an exact match for some defined option. If they have an
+ argument, it follows the option name in the same ARGV-element, separated
+ from the option name by a `=', or else the in next ARGV-element.
+ When `getopt' finds a long-named option, it returns 0 if that option's
+ `flag' field is nonzero, the value of the option's `val' field
+ if the `flag' field is zero.
+
+ The elements of ARGV aren't really const, because we permute them.
+ But we pretend they're const in the prototype to be compatible
+ with other systems.
+
+ LONGOPTS is a vector of `struct option' terminated by an
+ element containing a name which is zero.
+
+ LONGIND returns the index in LONGOPT of the long-named option found.
+ It is only valid when a long-named option has been found by the most
+ recent call.
+
+ If LONG_ONLY is nonzero, '-' as well as '--' can introduce
+ long-named options. */

+Barcodes generated in PostScript
+by Hans Schou http://www.schou.dk
+
+PostScript is a programming language. It has all the control structures
+needed for creating barcodes on the fly. With this example it is not
+needed to have another programming language than PostScript as the
+barcodes are generated within the PostScript printer.
+
+This contribution gives some examples of how to generate Interleave 2 of 5
+barcodes. Edit the bottom of i25.ps with a new number and send it to
+a PostScript printer to see an example.
+
+Usage, in PostScript:
+To draw a Interleave 2 of 5 use the following command in i25.ps
+ (123456789) BarCodeI25
+
+This method is very usefull used together with other scripts
+or programming language as it is only necessary to copy some
+files to the printer. No program execution is needed.
+
+
--- /dev/null
+
+The purpose of this program is to read a (scanned) image containing a
+barcode. The image is then interpreted and the barcode is decoded.
+The decoded string is outputted to stdout.
+
+Currently, only Code-128 is supported.
+
+The program is GPL'd and it's the work of Tuukka Toivonen.
+
+The home page for this and other programs by Tuukka is

+The Debian Package barcode
+----------------------------
+
+This Debian package is integrated in the upstream release of GNU
+barcode, maintained by Alessandro Rubini (rubini@gnu.org,
+rubini@prosa.it). Since I have no extended experience with Debian
+packages, I'm willing to accept any fixes that seem fit, as well as a
+real Debian maintainer for the Debian package.

+
+Overview
+********
+
+ The "barcode" package is mainly a C library for creating bar-code
+output files. It also includes a command line front-end and (in a
+foreseeable future) a graphic frontend.
+
+ The package is designed as a library because we think the main use
+for barcode-generation tools is inside more featured applications. The
+library addresses bar code printing as two distinct problems: creation
+of bar information and actual conversion to an output format. To this
+aim we use an intermediate representation for bar codes, which is
+currently documented in the `ps.c' source file (not in this document).
+
+ Note that the library and the accompanying material is released
+according to the GPL license, not the LGPL one. A copy of the GPL is
+included in the distribution tarball.
+
+\1f
+File: barcode.info, Node: The Barcode Object, Next: Supported Flags, Prev: Overview, Up: Top
+
+The Underlying Data Structure
+*****************************
+
+ Every barcode-related function acts on a data structure defined in
+the `barcode.h' header, which must be included by any C source file
+that uses the library. The header is installed by make install.
+
+ The definition of the data structure is included here for reference:
+
+ struct Barcode_Item {
+ int flags; /* type of encoding and other flags */
+ char *ascii; /* malloced */
+ char *partial; /* malloced too */
+ char *textinfo; /* information about text placement */
+ char *encoding; /* code name, filled by encoding engine */
+ int width, height; /* output units */
+ int xoff, yoff; /* output units */
+ int margin; /* output units */
+ double scalef; /* requested scaling for barcode */
+ int error; /* an errno-like value, in case of failure */
+ };
+
+ The exact meaning of each field and the various flags implemented are
+described in the following sections.
+
+ Even though you won't usually need to act on the contents of this
+structure, some of the functions in the library receive arguments that
+are directly related to one or more of these fields.

+
+The Fields
+==========
+
+`int flags;'
+ The flags are, as you may suspect, meant to specify the exact
+ behaviour of the library. They are often passed as an argument to
+ barcode functions and are discussed in the next section.
+
+`char *ascii;'
+`char *partial;'
+`char *textinfo;'
+`char *encoding;'
+ These fields are internally managed by the library, and you are
+ not expected to touch them if you use the provided API. All of
+ them are allocated with malloc.
+
+`int width;'
+`int height;'
+ They specify the width and height of the active barcode region
+ (i.e., excluding the white margin), in the units used to create
+ output data (for postscript they are points, 1/72th of an inch,
+ 0.352 mm). The fields can be either assigned to in the structure
+ or via Barcode_Position(), at your choice. If either value or
+ both are left to their default value of zero, the output engine
+ will assign default values according to the specified scaling
+ factor. If the specified width is bigger than needed (according to
+ the scaling factor), the output barcode will be centered in its
+ requested region. If either the width of the height are too small
+ for the specified scale factor, the output bar code will expand
+ symmetrically around the requested region.
+
+`int xoff;'
+`int yoff;'
+ The fields specify offset from the coordinate origin of the output
+ engine (for postscript, position 0,0 is the lower left corner of
+ the page). The fields can be either assigned to in the structure
+ or via Barcode_Position(), at your choice. The offset specifies
+ where the white margin begins, not where the first bar will be
+ printed. To print real ink to the specified position you should
+ set margin to 0.
+
+`int margin;'
+ The white margin that will be left around the printed area of the
+ bar code. The same margin is applied to all sides of the printed
+ area. The default value for the margin is defined in `barcode.h'
+ as BARCODE_DEFAULT_MARGIN (10).
+
+`double scalef;'
+ The enlarge or shrink value for the bar code over its default
+ dimension. The width and scalef fields interact deeply in the
+ creation of the output, and a complete description of the issues
+ appears later in this section.
+
+`int error;'
+ The field is used when a barcode function fails to host an
+ errno-like integer value.
+
+Use of the width and scalef fields.
+-----------------------------------
+
+ A width unit is the width of the thinnest bar and/or space in the
+chosen code; it defaults to 1 point if the output is postscript or
+encapsulated postscript.
+
+ Either or both the code width and the scale factor can be left
+unspecified (i.e., zero). The library deals with defaults in the
+following way:
+
+Both unspecified
+ If both the width and the scale factor are unspecified, the scale
+ factor will default to 1.0 and the width is calculated according
+ to the actual width of the bar code being printed.
+
+Width unspecified
+ If the width is not specified, it is calculated according to the
+ values of scalef.
+
+Scale factor unspecified
+ If the scale factor is not specified, it will be chosen so that
+ the generated bar code exactly fits the specified width.
+
+Both specified
+ The code will be printed inside the specified region according to
+ the specified scale factor. It will be aligned to the left. If,
+ however, the chosen width is too small for the specific bar code
+ and scaling factor, then the code will extend symmetrically to the
+ left and to the right of the chosen region.

+
+The Intermediate Representation
+===============================
+
+ The encoding functions print their output into the partial and
+texinfo fields of the barcode data structure. Those fields, together
+with position information, are then used to generate actual output.
+This is an informal description of the intermediate format.
+
+ The first char in partial tells how much extra space to add to the
+left of the bars. For EAN-13, it is used to leave space to print the
+first digit, other codes may have '0' for no-extra-space-needed.
+
+ The next characters are alternating bars and spaces, as multiples of
+the base dimension which is 1 unless the code is rescaled. Rescaling is
+calculated as the ratio from the requested width and the calculated
+width. Digits represent bar/space dimensions. Lower-case letters
+represent those bars that should extend lower than the others: 'a' is
+equivalent to '1', 'b' is '2' and so on up to 'i' which is equivalent to
+'9'. Other letters will be used for encoding-specific meanings, as soon
+as I implement them.
+
+ The textinfo string is made up of fields %lf:%lf:%c separated by
+blank space. The first integer is the x position of the character, the
+second is the font size (before rescaling) and the char item is the
+character to be printed.
+
+ Both the partial and textinfo strings may include "-" or "+" as
+special characters (in textinfo the char should be a stand-alone word).
+They state where the text should be printed: below the bars ("-",
+default) or above the bars. This is used, for example, to print the
+add-5 and add-2 codes to the right of UPC or EAN codes (the add-5
+extension is mostly used in ISBN codes).

+
+The Flags
+*********
+
+ The following flags are supported by version 0.98 of the library:
+
+`BARCODE_ENCODING_MASK'
+ The mask is used to extract the encoding-type identifier from the
+ flags field.
+
+`BARCODE_EAN'
+`BARCODE_UPC'
+`BARCODE_ISBN'
+`BARCODE_128B'
+`BARCODE_128C'
+`BARCODE_128'
+`BARCODE_128RAW'
+`BARCODE_39'
+`BARCODE_I25'
+`BARCODE_CBR'
+`BARCODE_MSI'
+`BARCODE_PLS'
+`BARCODE_93'
+ The currently supported encoding types: EAN (13 digits, 8 digits,
+ 13 + 2 add-on and 13 + 5 add-on), UPC (UPC-A, UPC-E, UPC-A with 2
+ or 5 digit add-on), ISBN (with or without the 5-digit add-on),
+ CODE128-B (the whole set of printable ASCII characters), CODE128-C
+ (two digits encoded by each barcode symbol), CODE128 (all ASCII
+ values), a "raw-input" pseudo-code that generates CODE128 output,
+ CODE39 (alphanumeric), "interleaved 2 of 5" (numeric), Codabar
+ (numeric plus a few symbols), MSI (numeric) and Plessey (hex
+ digits). *Note Supported Encodings::.
+
+`BARCODE_ANY'
+ This special encoding type (represented by a value of zero, so it
+ will be the default) tells the encoding procedure to look for the
+ first encoding type that can deal with a textual string.
+ Therefore, a 11-digit code will be printed as UPC (as well as
+ 6-digit, 11+2 and 11+5), a 12-digit (or 7-digit, or 12+2 or 12+5)
+ as EAN13, an ISBN code (with or without hyphens, with or without
+ add-5) will be encoded in its EAN13 representation, an even number
+ of digits is encoded using CODE128C and a generic string is
+ encoded using CODE128B. Since code-39 offers a much larger
+ representation for the same text string, code128-b is preferred
+ over code39 for alphanumeric strings.
+
+`BARCODE_NO_ASCII'
+ Instructs the engine not to print the ascii string on output. By
+ default the bar code is accompanied with an ascii version of the
+ text it encodes.
+
+`BARCODE_NO_CHECKSUM'
+ Instructs the engine not to add the checksum character to the
+ output. Not all the encoding types can drop the checksum; those
+ where the checksum is mandatory (like EAN and UPC) just ignore the
+ flag.
+
+`BARCODE_OUTPUT_MASK'
+ The mask is used to extract the output-type identifier from the
+ flags field.
+
+`BARCODE_OUT_PS'
+`BARCODE_OUT_EPS'
+`BARCODE_OUT_PCL'
+`BARCODE_OUT_PCL_III'
+ The currently supported encoding types: full-page postscript and
+ encapsulated postscript; PCL (print command language, for HP
+ printers) and PCL-III (same as PCL, but uses a font not available
+ on older printers).
+
+`BARCODE_OUT_NOHEADERS'
+ The flag instructs the printing engine not to print the header and
+ footer part of the file. This makes sense for the postscript
+ engine but might not make sense for other engines; such other
+ engines will silently ignore the flag just like the PCL back-end
+ does.

+
+Functions Exported by the Library
+*********************************
+
+ The functions included in the barcode library are declared in the
+header file barcode.h. They perform the following tasks:
+
+`struct Barcode_Item *Barcode_Create(char *text);'
+ The function creates a new barcode object to deal with a specified
+ text string. It returns NULL in case of failure and a pointer to
+ a barcode data structure in case of success.
+
+`int Barcode_Delete(struct Barcode_Item *bc);'
+ Destroy a barcode object. Always returns 0 (success)
+
+`int Barcode_Encode(struct Barcode_Item *bc, int flags);'
+ Encode the text included in the bc object. Valid flags are the
+ encoding type (other flags are ignored) and BARCODE_NO_CHECKSUM
+ (other flags are silently ignored); if the flag argument is zero,
+ bc->flags will apply. The function returns 0 on success and -1 in
+ case of error. After successful termination the data structure
+ will host the description of the bar code and its textual
+ representation, after a failure the error field will include the
+ reason of the failure.
+
+`int Barcode_Print(struct Barcode_Item *bc, FILE *f, int flags);'
+ Print the bar code described by bc to the specified file. Valid
+ flags are the output type, BARCODE_NO_ASCII and
+ BARCODE_OUT_NOHEADERS, other flags are ignored. If any of these
+ flags is zero, it will be inherited from bc->flags which therefore
+ takes precedence. The function returns 0 on success and -1 in case
+ of error (with bc->error set accordingly). In case of success, the
+ bar code is printed to the specified file, which won't be closed
+ after use.
+
+`int Barcode_Position(struct Barcode_Item *bc, int wid, int hei, int xoff, int yoff, double scalef);'
+ The function is a shortcut to assign values to the data structure.
+
+`int Barcode_Encode_and_Print(char *text, FILE *f, int wid, int hei, int xoff, int yoff, int flags);'
+ The function deals with the whole life of the barcode object by
+ calling the other functions; it uses all the specified flags.
+
+`int Barcode_Version(char *versionname);'
+ Returns the current version as an integer number of the form major
+ * 10000 + minor * 100 + release. Therefore, version 1.03.5 will be
+ returned as 10305 and version 0.53 as 5300. If the argument is
+ non-null, it will be used to return the version number as a
+ string. Note that the same information is available from two
+ preprocessor macros: BARCODE_VERSION (the string) and
+ BARCODE_VERSION_INT (the integer number).

+The barcode frontend program
+****************************
+
+ The barcode program is a front-end to access some features of the
+library from the command line. It is able to read user supplied
+strings from the command line or a data file (standard input by default)
+and encode all of them.
+
+* Menu:
+
+* The Command Line::
+
+\1f
+File: barcode.info, Node: The Command Line, Prev: The barcode Executable, Up: The barcode Executable
+
+The Command Line
+================
+
+ barcode accepts the following options:
+
+`--help or -h'
+ Print a usage summary and exit.
+
+`-i filename'
+ Identify a file where strings to be encoded are read from. If
+ missing (and if -b is not used) it defaults to standard input.
+ Each data line of the input file will be used to create one
+ barcode output.
+
+`-o filename'
+ Output file. It defaults to standard output.
+
+`-b string'
+ Specify a single "barcode" string to be encoded. The option can
+ be used multiple times in order to encode multiple strings (this
+ will result in multi-page postscript output or a table of barcodes
+ if -t is specified). The strings must match the encoding chosen;
+ if it doesn't match the program will print a warning to stderr and
+ generate "blank" output (although not zero-length). Please note
+ that a string including spaces or other special characters must be
+ properly quoted.
+
+`-e encoding'
+ encoding is the name of the chosen encoding format being used. It
+ defaults to the value of the environment variable BARCODE_ENCODING
+ or to auto detection if the environment is also unset.
+
+`-g geometry'
+ The geometry argument is of the form "[<width> x <height>] [+
+ <xmargin> + <ymargin>]" (with no intervening spaces). Unspecified
+ margin values will result in no margin; unspecified size results
+ in default size. The specified values represent print points by
+ default, and can be inches, millimeters or other units according
+ to the -u option or the BARCODE_UNIT environment variable. The
+ argument is used to place the printout code on the page. Note that
+ an additional white margin of 10 points is added to the printout.
+ If the option is unspecified, BARCODE_GEOMETRY is looked up in the
+ environment, if missing a default size and no margin (but the
+ default 10 points) are used.
+
+`-t table-geometry'
+ Used to print several barcodes to a single page, this option is
+ meant to be used to print stickers. The argument is of the form
+ "<columns> x <lines> [+ <leftmargin> + <bottommargin> [-
+ <rightmargin> [- <topmargin>]]]" (with no intervening spaces); if
+ missing, the top and right margin will default to be the same as
+ the bottom and left margin. The margins are specified in print
+ points or in the chosen unit (see -u below). If the option is not
+ specified, BARCODE_TABLE is looked up in the environment,
+ otherwise no table is printed and each barcode will get its own
+ page. The size (but not the position) of a barcode item within a
+ table can also be selected using -g (see "geometry" above),
+ without struggling with external and internal margins. I still
+ think management of geometries in a table is suboptimal, but I
+ can't make it better without introducing incompatibilities.
+
+`-m margin(s)'
+ Specifies an internal margin for each sticker in the table. The
+ argument is of the form "<xmargin>,<ymargin>" and the margin is
+ applied symmetrically to the sticker. If unspecified, the
+ environment variable BARCODE_MARGIN is used or a default internal
+ margin of 10 points is used.
+
+`-n'
+ "Numeric" output: don't print the ASCII form of the code, only the
+ bars.
+
+`-c'
+ No checksum character (for encodings that allow it, like code 39,
+ other codes, like UPC or EAN, ignore this option).
+
+`-E'
+ Encapsulated postscript (default is normal postscript). When the
+ output is generated as EPS only one barcode is encoded.
+
+`-P'
+ PCL output. Please note that the Y direction goes from top to
+ bottom for PCL, and the origin for an image is the top-left corner
+ instead of the bottom-left
+
+`-p pagesize'
+ Specify a non-default page size. The page size can be specified in
+ millimeters, inches or plain numbers (for example: "210x297mm",
+ "8.5x11in", "595x842"). A page specification as numbers will be
+ interpreted according to the current unit specification (see -u
+ below). If libpaper is available, you can also specify the page
+ size with its name, like "A3" or "letter" (libpaper is a standard
+ component of Debian GNU/Linux, but may be missing elsewhere). The
+ default page size is your system-wide default if libpaper is
+ there, A4 otherwise.
+
+`-u unit'
+ Choose the unit used in size specifications. Accepted values are
+ "mm", "cm", "in" and "pt". By default, the program will check
+ BARCODE_UNIT in the environment, and assume points otherwise (this
+ behaviour is compatible with 0.92 and previous versions. If -u
+ appears more than once, each instance will modified the behaviour
+ for the arguments at its right, as the command line is processes
+ left to right. The program internally works with points, and any
+ size is approximated to the nearest multiple of one point. The -u
+ option affect -g (geometry), -t (table) and -p (page size).

+
+Supported Encodings
+*******************
+
+ The program encodes text strings passed either on the command line
+(with -b) or retrieved from standard input. The text representation is
+interpreted according to the following rules. When auto-detection of
+the encoding is enabled (i.e, no explicit encoding type is specified),
+the encoding types are scanned to find one that can digest the text
+string. The following list of supported types is sorted in the same
+order the library uses when auto-detecting a suitable encoding for a
+string.
+
+EAN
+ The EAN frontend is similar to UPC; it accepts strings of digits,
+ 12 or 7 characters long. Strings of 13 or 8 characters are
+ accepted if the provided checksum digit is correct. I expect most
+ users to feed input without a checksum, though. The add-2 and
+ add-5 extension are accepted for both the EAN-13 and the EAN-8
+ encodings. The following are example of valid input strings:
+ "123456789012" (EAN-13), "1234567890128" (EAN-13 wih checksum),
+ "1234567" (EAN-8), "12345670 12345" (EAN-8 with checksum and
+ add-5), "123456789012 12" (EAN-13 with add-2), "123456789012
+ 12345" (EAN-13 with add-5).
+
+UPC
+ The UPC frontend accepts only strings made up of digits (and, if a
+ supplemental encoding is used, a blank to separate it). It
+ accepts strings of 11 or 12 digits (UPC-A) and 6 or 7 or 8 digits
+ (UPC-E).
+
+ The 12th digit of UPC-A is the checksum and is added by the
+ library if not specified in the input; if it is specified, it must
+ be the right checksum or the code is rejected as invalid. For
+ UPC-E, 6 digit are considered to be the middle part of the code, a
+ leading 0 is assumed and the checksum is added; 7 digits are
+ either considered the initial part (leading digit 0 or 1, checksum
+ missing) or the final part (checksum specified, leading 0
+ assumed); 8 digits are considered to be the complete code, with
+ leading 0 or 1 and checksum. For both UPC-A and UPC-E, a trailing
+ string of 2 digits or 5 digits is accepted as well. Therefore, the
+ following are examples of valid strings that can be encoded as UPC:
+ "01234567890" (UPC-A) "012345678905" (UPC-A with checksum),
+ "012345" (UPC-E), "01234567890 12" (UPC-A, add-2) and "01234567890
+ 12345" (UPC-A, add-5), "0123456 12" (UPC-E, add-2). Please note
+ that when setting BARCODE_ANY to auto-detect the encoding to be
+ used, 12-digit strings and 7-digit strings will always be
+ identified as EAN. This because I expect most user to provide
+ input without a checksum. If you need to specify UPC-with-checksum
+ as input you must explicitly set BARCODE_UPC as a flag or use -e
+ upc on the command line.
+
+ISBN
+ ISBN numbers are encoded as EAN-13 symbols, with an optional add-5
+ trailer. The ISBN frontend of the library accepts real ISBN
+ numbers and deals with any hyphen and, if present, the ISBN
+ checksum character before encoding data. Valid representations for
+ ISBN strings are for example: "1-56592-292-1", "3-89721-122-X" and
+ "3-89721-122-X 06900".
+
+CODE 128-B
+ This encoding can represent all of the printing ASCII characters,
+ from the space (32) to DEL (127). The checksum digit is mandatory
+ in this encoding.
+
+CODE 128-C
+ The "C" variation of Code-128 uses Code-128 symbols to represent
+ two digits at a time (Code-128 is made up of 104 symbols whose
+ interpretation is controlled by the start symbol being used). Code
+ 128-C is thus the most compact way to represent any even number of
+ digits. The encoder refuses to deal with an odd number of digits
+ because the caller is expected to provide proper padding to an
+ even number of digits. (Since Code-128 includes control symbols to
+ switch charset, it is theoretically possible to represent the odd
+ digit as a Code 128-A or 128-B symbol, but this tool doesn't
+ currently implement this option).
+
+CODE 128 RAW
+ Code-128 output represented symbol-by-symbol in the input string.
+ To override part of the problems outlined below in specifying
+ code128 symbols, this pseudo-encoding allows the used to specify a
+ list of code128 symbols separated by spaces. Each symbol is
+ represented by a number in the range 0-105. The list should
+ include the leading character.The checksum and the stop character
+ are automatically added by the library. Most likely this
+ pseudo-encoding will be used with BARCODE_NO_ASCII and some
+ external program to supply the printed text.
+
+CODE 39
+ The code-39 standard can encode uppercase letters, digits, the
+ blank space, plus, minus, dot, star, dollar, slash, percent. Any
+ string that is only composed of such characters is accepted by the
+ code-39 encoder. To avoid loosing information, the encoder refuses
+ to encode mixed-case strings (a lowercase string is nonetheless
+ accepted as a shortcut, but is encoded as uppercase).

+ This encoding can only represent an even number of digits (odd
+ digits are represented by bars, and even digits by the
+ interleaving spaces). The name stresses the fact that two of the
+ five items (bars or spaces) allocated to each symbol are wide,
+ while the rest are narrow. The checksum digit is optional (can be
+ disabled via BARCODE_NO_CHECKSUM). Since the number of digits,
+ including the checksum, must be even, a leading zero is inserted
+ in the string being encoded if needed (this is specifically stated
+ in the specs I have access to).
+
+CODE 128
+ Automatic selection between alphabet A, B and C of the Code-128
+ standard. This encoding can represent all ASCII symbols, from 0
+ (NUL) to 127 (DEL), as well as four special symbols, named F1, F2,
+ F3, F4. The set of symbols available in this encoding is not
+ easily represented as input to the barcode library, so the
+ following convention is used. In the input string, which is a
+ C-language null-terminated string, the NUL char is represented by
+ the value 128 (0x80, 0200) and the F1-F4 characters are
+ represented by the values 193-196 (0xc1-0xc4, 0301-0304). The
+ values have been chosen to ease their representation as escape
+ sequences.
+
+ Since the shell doesn't seem to interpret escape sequences on the
+ command line, the "-b" option cannot be easily used to designate
+ the strings to be encoded. As a workaround you can resort to the
+ command echo, either within back-ticks or used separately to
+ create a file that is then fed to the standard-input of barcode -
+ assuming your echo command processes escape sequences. The
+ newline character is especially though to encode (but not
+ impossible unless you use a csh variant.
+
+ These problems only apply to the command-line tool; the use of
+ library functions doesn't give any problem. In needed, you can use
+ the "code 128 raw" pseudo-encoding to represent code128 symbols by
+ their numerical value. This encoding is used late in the
+ auto-selection mechanism because (almost) any input string can be
+ represented using code128.
+
+CODABAR
+ Codabar can encode the ten digits and a few special symbols
+ (minus, plus, dollar, colon, bar, dot). The characters "A", "B",
+ "C" and "D" are used to represent four different start/stop
+ characters. The input string to the barcode library can include
+ the start and stop characters or not include them (in which case
+ "A" is used as start and "B" as stop). Start and stop characters
+ in the input string can be either all lowercase or all uppercase
+ and are always printed as uppercase.
+
+PLESSEY
+ Plessey barcodes can encode all the hexadecimal digits. Alphabetic
+ digits in the input string must either be all lowercase or all
+ uppercase. The output text is always uppercase.
+
+MSI
+ MSI can only encode the decimal digits. While the standard
+ specifies either one or two check digits, the current
+ implementation in this library only generates one check digit.
+
+CODE 93
+ The code-93 standard can natively encode 48 different characters,
+ including uppercase letters, digits, the blank space, plus, minus,
+ dot, star, dollar, slash, percent, as well as five special
+ characters: a start/stop delimiter and four "shift characters"
+ used for extended encoding. Using this "extended encoding"
+ method, any standard 7-bit ASCII character can be encoded, but it
+ takes up two symbol lengths in barcode if the character is not
+ natively supported (one of the 48). The encoder here fully
+ implements the code 93 encoding standard. Any characters natively
+ supported (A-Z, 0-9, ".+-/$&%") will be encoded as such - for any
+ other characters (such as lower case letters, brackets,
+ parentheses, etc.), the encoder will revert to extended encoding.
+ As a note, the option to exclude the checksum will eliminate the
+ two modulo-47 checksums (called C and K) from the barcode, but this
+ probably will make it unreadable by 99% of all scanning systems.
+ These checksums are specified to be used at the firmware level,
+ and their absence will be interpreted as an invalid barcode.

+
+PCL Output
+**********
+
+ While the default output is Postscript (possibly EPS), and Postscript
+can be post-processed to almost anything, it is sometimes desirable to
+create output directly usable by the specific printer at hand. PCL is
+currently supported as an output format for this reason. Please note
+that the Y coordinate for PCL goes from top to bottom, while for
+Postscript it goes from bottom to top. Consistently, while in
+Postscript you specify the bottom-left corner as origin, for PCL you
+specify the top-left corner.
+
+ Barcode output for PCL Printers (HP LaserJet and compatibles), was
+developed using PCL5 Reference manuals from HP. that really refers to
+these printers:
+ * LaserJet III, III P, III D, III Si,
+
+ * LaserJet 4 family
+
+ * LaserJet 5 family
+
+ * LaserJet 6 family
+
+ * Color LaserJet
+
+ * DeskJet 1200 and 1600.
+
+
+ However, barcode printing uses a very small subset of PCL, probably
+also LaserJet II should print it without problem, but the resulting
+text may be horrible.
+
+ The only real difference from one printer to another really depends
+on which font are available in the printer, used in printing the label
+associated to the bars (if requested).
+
+ Earlier LaserJet supports only bitmaps fonts, so these are not
+"scalable". (Ljet II ?), Also these fonts, when available, have a
+specified direction, and not all of them are available in both Portrait
+and Landscape mode.
+
+ From LaserJet 4 series, (except 4L/5L that are entry-level printers),
+Arial scalable font should be available, so it's the "default font"
+used by this program.
+
+ LaserJet III series printers (and 4L, 5L), don't feature "Arial" as a
+resident font, so you should use BARCODE_OUT_PCL_III instead of
+BARCODE_OUT_PCL., and font the font used will be "Univers" instead of
+"Arial".
+
+ Results on compatible printers, may depend on consistency of PCL5
+compatibility, in doubt, try BARCODE_OUT_PCL_III
+
+ PJL commands are not used here, as it's not very compatible.
+
+ Tested Printers:
+ * Hp LaserJet 4050
+
+ * Hp LaserJet 2100
+
+ * Epson N-1200 emul PCL
+
+ * Toshiba DP2570 (copier) + PCL option
+
+ * Epson EPL-7100 emul. HP LaserJet II: bars print fine but text is
+ bad.

+************************
+
+ The current management of borders/margins is far from optimal. The
+"default" margin applied by the library interferes with the external
+representation, but I feel it is mandatory to avoid creating barcode
+output with no surrounding white space (the problem is especially
+relevant for EPS output).
+
+ EAN-128 is not (yet) supported. I plan to implement it pretty soon
+and then bless the package as version 1.0.

+This is barcode.info, produced by makeinfo version 4.0 from
+barcode.texinfo.
+
+ This file is the User's Manual for the barcode library (version
+0.98).
+
+
+
+
+*Node: Overview
+ Overview
+ ********
+
+ The "barcode" package is mainly a C library for creating bar-code
+output files. It also includes a command line front-end and (in a
+foreseeable future) a graphic frontend.
+
+ The package is designed as a library because we think the main use
+for barcode-generation tools is inside more featured applications. The
+library addresses bar code printing as two distinct problems: creation
+of bar information and actual conversion to an output format. To this
+aim we use an intermediate representation for bar codes, which is
+currently documented in the `ps.c' source file (not in this document).
+
+ Note that the library and the accompanying material is released
+according to the GPL license, not the LGPL one. A copy of the GPL is
+included in the distribution tarball.
+
+
+
+
+*Node: The Barcode Object
+ The Underlying Data Structure
+ *****************************
+
+ Every barcode-related function acts on a data structure defined in
+the `barcode.h' header, which must be included by any C source file
+that uses the library. The header is installed by make install.
+
+ The definition of the data structure is included here for reference:
+
+ struct Barcode_Item {
+ int flags; /* type of encoding and other flags */
+ char *ascii; /* malloced */
+ char *partial; /* malloced too */
+ char *textinfo; /* information about text placement */
+ char *encoding; /* code name, filled by encoding engine */
+ int width, height; /* output units */
+ int xoff, yoff; /* output units */
+ int margin; /* output units */
+ double scalef; /* requested scaling for barcode */
+ int error; /* an errno-like value, in case of failure */
+ };
+
+ The exact meaning of each field and the various flags implemented are
+described in the following sections.
+
+ Even though you won't usually need to act on the contents of this
+structure, some of the functions in the library receive arguments that
+are directly related to one or more of these fields.
+
+
+
+
+*Node: The Field List
+ The Fields
+ ==========
+
+`int flags;'
+ The flags are, as you may suspect, meant to specify the exact
+ behaviour of the library. They are often passed as an argument to
+ barcode functions and are discussed in the next section.
+
+`char *ascii;'
+`char *partial;'
+`char *textinfo;'
+`char *encoding;'
+ These fields are internally managed by the library, and you are
+ not expected to touch them if you use the provided API. All of
+ them are allocated with malloc.
+
+`int width;'
+`int height;'
+ They specify the width and height of the active barcode region
+ (i.e., excluding the white margin), in the units used to create
+ output data (for postscript they are points, 1/72th of an inch,
+ 0.352 mm). The fields can be either assigned to in the structure
+ or via Barcode_Position(), at your choice. If either value or
+ both are left to their default value of zero, the output engine
+ will assign default values according to the specified scaling
+ factor. If the specified width is bigger than needed (according to
+ the scaling factor), the output barcode will be centered in its
+ requested region. If either the width of the height are too small
+ for the specified scale factor, the output bar code will expand
+ symmetrically around the requested region.
+
+`int xoff;'
+`int yoff;'
+ The fields specify offset from the coordinate origin of the output
+ engine (for postscript, position 0,0 is the lower left corner of
+ the page). The fields can be either assigned to in the structure
+ or via Barcode_Position(), at your choice. The offset specifies
+ where the white margin begins, not where the first bar will be
+ printed. To print real ink to the specified position you should
+ set margin to 0.
+
+`int margin;'
+ The white margin that will be left around the printed area of the
+ bar code. The same margin is applied to all sides of the printed
+ area. The default value for the margin is defined in `barcode.h'
+ as BARCODE_DEFAULT_MARGIN (10).
+
+`double scalef;'
+ The enlarge or shrink value for the bar code over its default
+ dimension. The width and scalef fields interact deeply in the
+ creation of the output, and a complete description of the issues
+ appears later in this section.
+
+`int error;'
+ The field is used when a barcode function fails to host an
+ errno-like integer value.
+
+Use of the width and scalef fields.
+-----------------------------------
+
+ A width unit is the width of the thinnest bar and/or space in the
+chosen code; it defaults to 1 point if the output is postscript or
+encapsulated postscript.
+
+ Either or both the code width and the scale factor can be left
+unspecified (i.e., zero). The library deals with defaults in the
+following way:
+
+Both unspecified
+ If both the width and the scale factor are unspecified, the scale
+ factor will default to 1.0 and the width is calculated according
+ to the actual width of the bar code being printed.
+
+Width unspecified
+ If the width is not specified, it is calculated according to the
+ values of scalef.
+
+Scale factor unspecified
+ If the scale factor is not specified, it will be chosen so that
+ the generated bar code exactly fits the specified width.
+
+Both specified
+ The code will be printed inside the specified region according to
+ the specified scale factor. It will be aligned to the left. If,
+ however, the chosen width is too small for the specific bar code
+ and scaling factor, then the code will extend symmetrically to the
+ left and to the right of the chosen region.
+
+
+
+
+*Node: The Intermediate Representation
+ The Intermediate Representation
+ ===============================
+
+ The encoding functions print their output into the partial and
+texinfo fields of the barcode data structure. Those fields, together
+with position information, are then used to generate actual output.
+This is an informal description of the intermediate format.
+
+ The first char in partial tells how much extra space to add to the
+left of the bars. For EAN-13, it is used to leave space to print the
+first digit, other codes may have '0' for no-extra-space-needed.
+
+ The next characters are alternating bars and spaces, as multiples of
+the base dimension which is 1 unless the code is rescaled. Rescaling is
+calculated as the ratio from the requested width and the calculated
+width. Digits represent bar/space dimensions. Lower-case letters
+represent those bars that should extend lower than the others: 'a' is
+equivalent to '1', 'b' is '2' and so on up to 'i' which is equivalent to
+'9'. Other letters will be used for encoding-specific meanings, as soon
+as I implement them.
+
+ The textinfo string is made up of fields %lf:%lf:%c separated by
+blank space. The first integer is the x position of the character, the
+second is the font size (before rescaling) and the char item is the
+character to be printed.
+
+ Both the partial and textinfo strings may include "-" or "+" as
+special characters (in textinfo the char should be a stand-alone word).
+They state where the text should be printed: below the bars ("-",
+default) or above the bars. This is used, for example, to print the
+add-5 and add-2 codes to the right of UPC or EAN codes (the add-5
+extension is mostly used in ISBN codes).
+
+
+
+
+*Node: Supported Flags
+ The Flags
+ *********
+
+ The following flags are supported by version 0.98 of the library:
+
+`BARCODE_ENCODING_MASK'
+ The mask is used to extract the encoding-type identifier from the
+ flags field.
+
+`BARCODE_EAN'
+`BARCODE_UPC'
+`BARCODE_ISBN'
+`BARCODE_128B'
+`BARCODE_128C'
+`BARCODE_128'
+`BARCODE_128RAW'
+`BARCODE_39'
+`BARCODE_I25'
+`BARCODE_CBR'
+`BARCODE_MSI'
+`BARCODE_PLS'
+`BARCODE_93'
+ The currently supported encoding types: EAN (13 digits, 8 digits,
+ 13 + 2 add-on and 13 + 5 add-on), UPC (UPC-A, UPC-E, UPC-A with 2
+ or 5 digit add-on), ISBN (with or without the 5-digit add-on),
+ CODE128-B (the whole set of printable ASCII characters), CODE128-C
+ (two digits encoded by each barcode symbol), CODE128 (all ASCII
+ values), a "raw-input" pseudo-code that generates CODE128 output,
+ CODE39 (alphanumeric), "interleaved 2 of 5" (numeric), Codabar
+ (numeric plus a few symbols), MSI (numeric) and Plessey (hex
+ digits). *Note Supported Encodings::.
+
+`BARCODE_ANY'
+ This special encoding type (represented by a value of zero, so it
+ will be the default) tells the encoding procedure to look for the
+ first encoding type that can deal with a textual string.
+ Therefore, a 11-digit code will be printed as UPC (as well as
+ 6-digit, 11+2 and 11+5), a 12-digit (or 7-digit, or 12+2 or 12+5)
+ as EAN13, an ISBN code (with or without hyphens, with or without
+ add-5) will be encoded in its EAN13 representation, an even number
+ of digits is encoded using CODE128C and a generic string is
+ encoded using CODE128B. Since code-39 offers a much larger
+ representation for the same text string, code128-b is preferred
+ over code39 for alphanumeric strings.
+
+`BARCODE_NO_ASCII'
+ Instructs the engine not to print the ascii string on output. By
+ default the bar code is accompanied with an ascii version of the
+ text it encodes.
+
+`BARCODE_NO_CHECKSUM'
+ Instructs the engine not to add the checksum character to the
+ output. Not all the encoding types can drop the checksum; those
+ where the checksum is mandatory (like EAN and UPC) just ignore the
+ flag.
+
+`BARCODE_OUTPUT_MASK'
+ The mask is used to extract the output-type identifier from the
+ flags field.
+
+`BARCODE_OUT_PS'
+`BARCODE_OUT_EPS'
+`BARCODE_OUT_PCL'
+`BARCODE_OUT_PCL_III'
+ The currently supported encoding types: full-page postscript and
+ encapsulated postscript; PCL (print command language, for HP
+ printers) and PCL-III (same as PCL, but uses a font not available
+ on older printers).
+
+`BARCODE_OUT_NOHEADERS'
+ The flag instructs the printing engine not to print the header and
+ footer part of the file. This makes sense for the postscript
+ engine but might not make sense for other engines; such other
+ engines will silently ignore the flag just like the PCL back-end
+ does.
+
+
+
+
+*Node: The API
+ Functions Exported by the Library
+ *********************************
+
+ The functions included in the barcode library are declared in the
+header file barcode.h. They perform the following tasks:
+
+`struct Barcode_Item *Barcode_Create(char *text);'
+ The function creates a new barcode object to deal with a specified
+ text string. It returns NULL in case of failure and a pointer to
+ a barcode data structure in case of success.
+
+`int Barcode_Delete(struct Barcode_Item *bc);'
+ Destroy a barcode object. Always returns 0 (success)
+
+`int Barcode_Encode(struct Barcode_Item *bc, int flags);'
+ Encode the text included in the bc object. Valid flags are the
+ encoding type (other flags are ignored) and BARCODE_NO_CHECKSUM
+ (other flags are silently ignored); if the flag argument is zero,
+ bc->flags will apply. The function returns 0 on success and -1 in
+ case of error. After successful termination the data structure
+ will host the description of the bar code and its textual
+ representation, after a failure the error field will include the
+ reason of the failure.
+
+`int Barcode_Print(struct Barcode_Item *bc, FILE *f, int flags);'
+ Print the bar code described by bc to the specified file. Valid
+ flags are the output type, BARCODE_NO_ASCII and
+ BARCODE_OUT_NOHEADERS, other flags are ignored. If any of these
+ flags is zero, it will be inherited from bc->flags which therefore
+ takes precedence. The function returns 0 on success and -1 in case
+ of error (with bc->error set accordingly). In case of success, the
+ bar code is printed to the specified file, which won't be closed
+ after use.
+
+`int Barcode_Position(struct Barcode_Item *bc, int wid, int hei, int xoff, int yoff, double scalef);'
+ The function is a shortcut to assign values to the data structure.
+
+`int Barcode_Encode_and_Print(char *text, FILE *f, int wid, int hei, int xoff, int yoff, int flags);'
+ The function deals with the whole life of the barcode object by
+ calling the other functions; it uses all the specified flags.
+
+`int Barcode_Version(char *versionname);'
+ Returns the current version as an integer number of the form major
+ * 10000 + minor * 100 + release. Therefore, version 1.03.5 will be
+ returned as 10305 and version 0.53 as 5300. If the argument is
+ non-null, it will be used to return the version number as a
+ string. Note that the same information is available from two
+ preprocessor macros: BARCODE_VERSION (the string) and
+ BARCODE_VERSION_INT (the integer number).
+
+
+
+
+*Node: The barcode Executable
+ The barcode frontend program
+ ****************************
+
+ The barcode program is a front-end to access some features of the
+library from the command line. It is able to read user supplied
+strings from the command line or a data file (standard input by default)
+and encode all of them.
+
+
+
+
+*Node: The Command Line
+ The Command Line
+ ================
+
+ barcode accepts the following options:
+
+`--help or -h'
+ Print a usage summary and exit.
+
+`-i filename'
+ Identify a file where strings to be encoded are read from. If
+ missing (and if -b is not used) it defaults to standard input.
+ Each data line of the input file will be used to create one
+ barcode output.
+
+`-o filename'
+ Output file. It defaults to standard output.
+
+`-b string'
+ Specify a single "barcode" string to be encoded. The option can
+ be used multiple times in order to encode multiple strings (this
+ will result in multi-page postscript output or a table of barcodes
+ if -t is specified). The strings must match the encoding chosen;
+ if it doesn't match the program will print a warning to stderr and
+ generate "blank" output (although not zero-length). Please note
+ that a string including spaces or other special characters must be
+ properly quoted.
+
+`-e encoding'
+ encoding is the name of the chosen encoding format being used. It
+ defaults to the value of the environment variable BARCODE_ENCODING
+ or to auto detection if the environment is also unset.
+
+`-g geometry'
+ The geometry argument is of the form "[<width> x <height>] [+
+ <xmargin> + <ymargin>]" (with no intervening spaces). Unspecified
+ margin values will result in no margin; unspecified size results
+ in default size. The specified values represent print points by
+ default, and can be inches, millimeters or other units according
+ to the -u option or the BARCODE_UNIT environment variable. The
+ argument is used to place the printout code on the page. Note that
+ an additional white margin of 10 points is added to the printout.
+ If the option is unspecified, BARCODE_GEOMETRY is looked up in the
+ environment, if missing a default size and no margin (but the
+ default 10 points) are used.
+
+`-t table-geometry'
+ Used to print several barcodes to a single page, this option is
+ meant to be used to print stickers. The argument is of the form
+ "<columns> x <lines> [+ <leftmargin> + <bottommargin> [-
+ <rightmargin> [- <topmargin>]]]" (with no intervening spaces); if
+ missing, the top and right margin will default to be the same as
+ the bottom and left margin. The margins are specified in print
+ points or in the chosen unit (see -u below). If the option is not
+ specified, BARCODE_TABLE is looked up in the environment,
+ otherwise no table is printed and each barcode will get its own
+ page. The size (but not the position) of a barcode item within a
+ table can also be selected using -g (see "geometry" above),
+ without struggling with external and internal margins. I still
+ think management of geometries in a table is suboptimal, but I
+ can't make it better without introducing incompatibilities.
+
+`-m margin(s)'
+ Specifies an internal margin for each sticker in the table. The
+ argument is of the form "<xmargin>,<ymargin>" and the margin is
+ applied symmetrically to the sticker. If unspecified, the
+ environment variable BARCODE_MARGIN is used or a default internal
+ margin of 10 points is used.
+
+`-n'
+ "Numeric" output: don't print the ASCII form of the code, only the
+ bars.
+
+`-c'
+ No checksum character (for encodings that allow it, like code 39,
+ other codes, like UPC or EAN, ignore this option).
+
+`-E'
+ Encapsulated postscript (default is normal postscript). When the
+ output is generated as EPS only one barcode is encoded.
+
+`-P'
+ PCL output. Please note that the Y direction goes from top to
+ bottom for PCL, and the origin for an image is the top-left corner
+ instead of the bottom-left
+
+`-p pagesize'
+ Specify a non-default page size. The page size can be specified in
+ millimeters, inches or plain numbers (for example: "210x297mm",
+ "8.5x11in", "595x842"). A page specification as numbers will be
+ interpreted according to the current unit specification (see -u
+ below). If libpaper is available, you can also specify the page
+ size with its name, like "A3" or "letter" (libpaper is a standard
+ component of Debian GNU/Linux, but may be missing elsewhere). The
+ default page size is your system-wide default if libpaper is
+ there, A4 otherwise.
+
+`-u unit'
+ Choose the unit used in size specifications. Accepted values are
+ "mm", "cm", "in" and "pt". By default, the program will check
+ BARCODE_UNIT in the environment, and assume points otherwise (this
+ behaviour is compatible with 0.92 and previous versions. If -u
+ appears more than once, each instance will modified the behaviour
+ for the arguments at its right, as the command line is processes
+ left to right. The program internally works with points, and any
+ size is approximated to the nearest multiple of one point. The -u
+ option affect -g (geometry), -t (table) and -p (page size).
+
+
+
+
+*Node: Supported Encodings
+ Supported Encodings
+ *******************
+
+ The program encodes text strings passed either on the command line
+(with -b) or retrieved from standard input. The text representation is
+interpreted according to the following rules. When auto-detection of
+the encoding is enabled (i.e, no explicit encoding type is specified),
+the encoding types are scanned to find one that can digest the text
+string. The following list of supported types is sorted in the same
+order the library uses when auto-detecting a suitable encoding for a
+string.
+
+EAN
+ The EAN frontend is similar to UPC; it accepts strings of digits,
+ 12 or 7 characters long. Strings of 13 or 8 characters are
+ accepted if the provided checksum digit is correct. I expect most
+ users to feed input without a checksum, though. The add-2 and
+ add-5 extension are accepted for both the EAN-13 and the EAN-8
+ encodings. The following are example of valid input strings:
+ "123456789012" (EAN-13), "1234567890128" (EAN-13 wih checksum),
+ "1234567" (EAN-8), "12345670 12345" (EAN-8 with checksum and
+ add-5), "123456789012 12" (EAN-13 with add-2), "123456789012
+ 12345" (EAN-13 with add-5).
+
+UPC
+ The UPC frontend accepts only strings made up of digits (and, if a
+ supplemental encoding is used, a blank to separate it). It
+ accepts strings of 11 or 12 digits (UPC-A) and 6 or 7 or 8 digits
+ (UPC-E).
+
+ The 12th digit of UPC-A is the checksum and is added by the
+ library if not specified in the input; if it is specified, it must
+ be the right checksum or the code is rejected as invalid. For
+ UPC-E, 6 digit are considered to be the middle part of the code, a
+ leading 0 is assumed and the checksum is added; 7 digits are
+ either considered the initial part (leading digit 0 or 1, checksum
+ missing) or the final part (checksum specified, leading 0
+ assumed); 8 digits are considered to be the complete code, with
+ leading 0 or 1 and checksum. For both UPC-A and UPC-E, a trailing
+ string of 2 digits or 5 digits is accepted as well. Therefore, the
+ following are examples of valid strings that can be encoded as UPC:
+ "01234567890" (UPC-A) "012345678905" (UPC-A with checksum),
+ "012345" (UPC-E), "01234567890 12" (UPC-A, add-2) and "01234567890
+ 12345" (UPC-A, add-5), "0123456 12" (UPC-E, add-2). Please note
+ that when setting BARCODE_ANY to auto-detect the encoding to be
+ used, 12-digit strings and 7-digit strings will always be
+ identified as EAN. This because I expect most user to provide
+ input without a checksum. If you need to specify UPC-with-checksum
+ as input you must explicitly set BARCODE_UPC as a flag or use -e
+ upc on the command line.
+
+ISBN
+ ISBN numbers are encoded as EAN-13 symbols, with an optional add-5
+ trailer. The ISBN frontend of the library accepts real ISBN
+ numbers and deals with any hyphen and, if present, the ISBN
+ checksum character before encoding data. Valid representations for
+ ISBN strings are for example: "1-56592-292-1", "3-89721-122-X" and
+ "3-89721-122-X 06900".
+
+CODE 128-B
+ This encoding can represent all of the printing ASCII characters,
+ from the space (32) to DEL (127). The checksum digit is mandatory
+ in this encoding.
+
+CODE 128-C
+ The "C" variation of Code-128 uses Code-128 symbols to represent
+ two digits at a time (Code-128 is made up of 104 symbols whose
+ interpretation is controlled by the start symbol being used). Code
+ 128-C is thus the most compact way to represent any even number of
+ digits. The encoder refuses to deal with an odd number of digits
+ because the caller is expected to provide proper padding to an
+ even number of digits. (Since Code-128 includes control symbols to
+ switch charset, it is theoretically possible to represent the odd
+ digit as a Code 128-A or 128-B symbol, but this tool doesn't
+ currently implement this option).
+
+CODE 128 RAW
+ Code-128 output represented symbol-by-symbol in the input string.
+ To override part of the problems outlined below in specifying
+ code128 symbols, this pseudo-encoding allows the used to specify a
+ list of code128 symbols separated by spaces. Each symbol is
+ represented by a number in the range 0-105. The list should
+ include the leading character.The checksum and the stop character
+ are automatically added by the library. Most likely this
+ pseudo-encoding will be used with BARCODE_NO_ASCII and some
+ external program to supply the printed text.
+
+CODE 39
+ The code-39 standard can encode uppercase letters, digits, the
+ blank space, plus, minus, dot, star, dollar, slash, percent. Any
+ string that is only composed of such characters is accepted by the
+ code-39 encoder. To avoid loosing information, the encoder refuses
+ to encode mixed-case strings (a lowercase string is nonetheless
+ accepted as a shortcut, but is encoded as uppercase).
+
+INTERLEAVED 2 OF 5
+ This encoding can only represent an even number of digits (odd
+ digits are represented by bars, and even digits by the
+ interleaving spaces). The name stresses the fact that two of the
+ five items (bars or spaces) allocated to each symbol are wide,
+ while the rest are narrow. The checksum digit is optional (can be
+ disabled via BARCODE_NO_CHECKSUM). Since the number of digits,
+ including the checksum, must be even, a leading zero is inserted
+ in the string being encoded if needed (this is specifically stated
+ in the specs I have access to).
+
+CODE 128
+ Automatic selection between alphabet A, B and C of the Code-128
+ standard. This encoding can represent all ASCII symbols, from 0
+ (NUL) to 127 (DEL), as well as four special symbols, named F1, F2,
+ F3, F4. The set of symbols available in this encoding is not
+ easily represented as input to the barcode library, so the
+ following convention is used. In the input string, which is a
+ C-language null-terminated string, the NUL char is represented by
+ the value 128 (0x80, 0200) and the F1-F4 characters are
+ represented by the values 193-196 (0xc1-0xc4, 0301-0304). The
+ values have been chosen to ease their representation as escape
+ sequences.
+
+ Since the shell doesn't seem to interpret escape sequences on the
+ command line, the "-b" option cannot be easily used to designate
+ the strings to be encoded. As a workaround you can resort to the
+ command echo, either within back-ticks or used separately to
+ create a file that is then fed to the standard-input of barcode -
+ assuming your echo command processes escape sequences. The
+ newline character is especially though to encode (but not
+ impossible unless you use a csh variant.
+
+ These problems only apply to the command-line tool; the use of
+ library functions doesn't give any problem. In needed, you can use
+ the "code 128 raw" pseudo-encoding to represent code128 symbols by
+ their numerical value. This encoding is used late in the
+ auto-selection mechanism because (almost) any input string can be
+ represented using code128.
+
+CODABAR
+ Codabar can encode the ten digits and a few special symbols
+ (minus, plus, dollar, colon, bar, dot). The characters "A", "B",
+ "C" and "D" are used to represent four different start/stop
+ characters. The input string to the barcode library can include
+ the start and stop characters or not include them (in which case
+ "A" is used as start and "B" as stop). Start and stop characters
+ in the input string can be either all lowercase or all uppercase
+ and are always printed as uppercase.
+
+PLESSEY
+ Plessey barcodes can encode all the hexadecimal digits. Alphabetic
+ digits in the input string must either be all lowercase or all
+ uppercase. The output text is always uppercase.
+
+MSI
+ MSI can only encode the decimal digits. While the standard
+ specifies either one or two check digits, the current
+ implementation in this library only generates one check digit.
+
+CODE 93
+ The code-93 standard can natively encode 48 different characters,
+ including uppercase letters, digits, the blank space, plus, minus,
+ dot, star, dollar, slash, percent, as well as five special
+ characters: a start/stop delimiter and four "shift characters"
+ used for extended encoding. Using this "extended encoding"
+ method, any standard 7-bit ASCII character can be encoded, but it
+ takes up two symbol lengths in barcode if the character is not
+ natively supported (one of the 48). The encoder here fully
+ implements the code 93 encoding standard. Any characters natively
+ supported (A-Z, 0-9, ".+-/$&%") will be encoded as such - for any
+ other characters (such as lower case letters, brackets,
+ parentheses, etc.), the encoder will revert to extended encoding.
+ As a note, the option to exclude the checksum will eliminate the
+ two modulo-47 checksums (called C and K) from the barcode, but this
+ probably will make it unreadable by 99% of all scanning systems.
+ These checksums are specified to be used at the firmware level,
+ and their absence will be interpreted as an invalid barcode.
+
+
+
+
+*Node: PCL Output
+ PCL Output
+ **********
+
+ While the default output is Postscript (possibly EPS), and Postscript
+can be post-processed to almost anything, it is sometimes desirable to
+create output directly usable by the specific printer at hand. PCL is
+currently supported as an output format for this reason. Please note
+that the Y coordinate for PCL goes from top to bottom, while for
+Postscript it goes from bottom to top. Consistently, while in
+Postscript you specify the bottom-left corner as origin, for PCL you
+specify the top-left corner.
+
+ Barcode output for PCL Printers (HP LaserJet and compatibles), was
+developed using PCL5 Reference manuals from HP. that really refers to
+these printers:
+ * LaserJet III, III P, III D, III Si,
+
+ * LaserJet 4 family
+
+ * LaserJet 5 family
+
+ * LaserJet 6 family
+
+ * Color LaserJet
+
+ * DeskJet 1200 and 1600.
+
+
+ However, barcode printing uses a very small subset of PCL, probably
+also LaserJet II should print it without problem, but the resulting
+text may be horrible.
+
+ The only real difference from one printer to another really depends
+on which font are available in the printer, used in printing the label
+associated to the bars (if requested).
+
+ Earlier LaserJet supports only bitmaps fonts, so these are not
+"scalable". (Ljet II ?), Also these fonts, when available, have a
+specified direction, and not all of them are available in both Portrait
+and Landscape mode.
+
+ From LaserJet 4 series, (except 4L/5L that are entry-level printers),
+Arial scalable font should be available, so it's the "default font"
+used by this program.
+
+ LaserJet III series printers (and 4L, 5L), don't feature "Arial" as a
+resident font, so you should use BARCODE_OUT_PCL_III instead of
+BARCODE_OUT_PCL., and font the font used will be "Univers" instead of
+"Arial".
+
+ Results on compatible printers, may depend on consistency of PCL5
+compatibility, in doubt, try BARCODE_OUT_PCL_III
+
+ PJL commands are not used here, as it's not very compatible.
+
+ Tested Printers:
+ * Hp LaserJet 4050

+"default" margin applied by the library interferes with the external
+representation, but I feel it is mandatory to avoid creating barcode
+output with no surrounding white space (the problem is especially
+relevant for EPS output).
+
+ EAN-128 is not (yet) supported. I plan to implement it pretty soon
+and then bless the package as version 1.0.

+@chapter Overview
+
+The @dfn{barcode} package is mainly a C library for creating bar-code
+output files. It also includes a command line front-end and (in a
+foreseeable future) a graphic frontend.
+
+The package is designed as a library because we think the main use for
+barcode-generation tools is inside more featured applications. The
+library addresses bar code printing as two distinct problems: creation
+of bar information and actual conversion to an output format. To this
+aim we use an intermediate representation for bar codes, which is
+currently documented in the @file{ps.c} source file (not in this
+document).
+
+Note that the library and the accompanying material is released
+according to the GPL license, not the LGPL one. A copy of the GPL is
+included in the distribution tarball.
+
+%##########################################################################
+
+@node The Barcode Object, Supported Flags, Overview, Top
+@chapter The Underlying Data Structure
+
+Every barcode-related function acts on a data structure defined in the
+@file{barcode.h} header, which must be included by any C source file
+that uses the library. The header is installed by @t{make install}.
+
+The definition of the data structure is included here for reference:
+
+@lisp
+struct Barcode_Item @{
+ int flags; /* type of encoding and other flags */
+ char *ascii; /* malloced */
+ char *partial; /* malloced too */
+ char *textinfo; /* information about text placement */
+ char *encoding; /* code name, filled by encoding engine */
+ int width, height; /* output units */
+ int xoff, yoff; /* output units */
+ int margin; /* output units */
+ double scalef; /* requested scaling for barcode */
+ int error; /* an errno-like value, in case of failure */
+@};
+@end lisp
+
+The exact meaning of each field and the various flags implemented are
+described in the following sections.
+
+Even though you won't usually need to act on the contents of this
+structure, some of the functions in the library receive arguments that
+are directly related to one or more of these fields.
+

+@node The Field List, The Intermediate Representation, The Barcode Object, The Barcode Object
+@section The Fields
+
+@table @code
+
+@item int flags;
+
+ The flags are, as you may suspect, meant to specify the exact
+ behaviour of the library. They are often passed as an argument
+ to @i{barcode} functions and are discussed in the next section.
+
+@item char *ascii;
+@itemx char *partial;
+@itemx char *textinfo;
+@itemx char *encoding;
+
+ These fields are internally managed by the library, and you are
+ not expected to touch them if you use the provided API. All
+ of them are allocated with @i{malloc}.
+
+@item int width;
+@itemx int height;
+
+ They specify the width and height of the @i{active} barcode
+ region (i.e., excluding the white margin), in the units used
+ to create output data (for postscript they are points, 1/72th
+ of an inch, 0.352 mm). The fields can be either assigned to
+ in the structure or via @i{Barcode_Position()}, at your
+ choice. If either value or both are left to their default
+ value of zero, the output engine will assign default values
+ according to the specified scaling factor. If the specified
+ width is bigger than needed (according to the scaling factor),
+ the output barcode will be centered in its requested
+ region. If either the width of the height are too small for
+ the specified scale factor, the output bar code will expand
+ symmetrically around the requested region.
+
+@item int xoff;
+@itemx int yoff;
+
+ The fields specify offset from the coordinate origin of the
+ output engine (for postscript, position 0,0 is the lower left
+ corner of the page). The fields can be either assigned to in
+ the structure or via @i{Barcode_Position()}, at your choice.
+ The offset specifies where the white margin begins, not where
+ the first bar will be printed. To print real ink to the
+ specified position you should set @i{margin} to 0.
+
+@item int margin;
+
+ The white margin that will be left around the printed area of
+ the bar code. The same margin is applied to all sides of the
+ printed area. The default value for the margin is defined in
+ @file{barcode.h} as @t{BARCODE_DEFAULT_MARGIN} (10).
+
+@item double scalef;
+
+ The enlarge or shrink value for the bar code over its default
+ dimension. The @i{width} and @i{scalef} fields interact deeply
+ in the creation of the output, and a complete description of
+ the issues appears later in this section.
+
+@item int error;
+
+ The field is used when a @i{barcode} function fails to host
+ an @t{errno}-like integer value.
+
+@end table
+
+
+@unnumberedsubsec Use of the @i{width} and @i{scalef} fields.
+
+A width unit is the width of the thinnest bar and/or space in the
+chosen code; it defaults to 1 point if the output is postscript or
+encapsulated postscript.
+
+Either or both the code width and the scale factor can be left
+unspecified (i.e., zero). The library deals with defaults in the
+following way:
+
+@table @i
+
+@item Both unspecified
+
+ If both the width and the scale factor are unspecified, the
+ scale factor will default to 1.0 and the width is calculated
+ according to the actual width of the bar code being printed.
+
+@item Width unspecified
+
+ If the width is not specified, it is calculated according to
+ the values of @i{scalef}.
+
+@item Scale factor unspecified
+
+ If the scale factor is not specified, it will be chosen so
+ that the generated bar code exactly fits the specified width.
+
+@item Both specified
+
+ The code will be printed inside the specified region according
+ to the specified scale factor. It will be aligned to the left.
+ If, however, the chosen width is too small for the specific
+ bar code and scaling factor, then the code will extend
+ symmetrically to the left and to the right of the chosen
+ region.
+
+@end table
+
+%--------------------------------------------------------------------------
+@node The Intermediate Representation, , The Field List, The Barcode Object
+@section The Intermediate Representation
+
+The encoding functions print their output into the @t{partial} and
+@t{texinfo} fields of the barcode data structure. Those fields, together
+with position information, are then used to generate actual output.
+This is an informal description of the intermediate format.
+
+The first char in @t{partial} tells how much extra space to add to the
+left of the bars. For EAN-13, it is used to leave space to print the
+first digit, other codes may have '0' for no-extra-space-needed.
+
+The next characters are alternating bars and spaces, as multiples of the
+base dimension which is 1 unless the code is rescaled. Rescaling is
+calculated as the ratio from the requested width and the calculated
+width. Digits represent bar/space dimensions. Lower-case letters
+represent those bars that should extend lower than the others: 'a' is
+equivalent to '1', 'b' is '2' and so on up to 'i' which is equivalent to
+'9'. Other letters will be used for encoding-specific meanings, as soon
+as I implement them.
+
+The @t{textinfo} string is made up of fields @t{%lf:%lf:%c} separated by
+blank space. The first integer is the x position of the character,
+the second is the font size (before rescaling) and the char item is
+the character to be printed.
+
+Both the @t{partial} and @t{textinfo} strings may include ``@t{-}'' or
+``@t{+}'' as special characters (in @t{textinfo} the char should be a
+stand-alone word). They state where the text should be printed: below
+the bars (``@t{-}'', default) or above the bars. This is used, for
+example, to print the add-5 and add-2 codes to the right of UPC or EAN
+codes (the add-5 extension is mostly used in ISBN codes).

+
+The following flags are supported by version @value{version} of the

+
+@item BARCODE_ENCODING_MASK
+
+ The mask is used to extract the encoding-type identifier from
+ the @i{flags} field.
+
+@item BARCODE_EAN

+ UPC-A with 2 or 5 digit add-on), ISBN (with or without the
+ 5-digit add-on), CODE128-B (the whole set of printable
+ ASCII characters), CODE128-C (two digits encoded by each barcode
+ symbol), CODE128 (all ASCII values), a ``raw-input'' pseudo-code
+ that generates CODE128 output, CODE39 (alphanumeric),
+ "interleaved 2 of 5" (numeric), Codabar (numeric plus a few
+ symbols), MSI (numeric) and Plessey (hex digits).
+ @xref{Supported Encodings}.
+
+@item BARCODE_ANY
+
+ This special encoding type (represented by a value of zero, so
+ it will be the default) tells the encoding procedure to look
+ for the first encoding type that can deal with a textual
+ string. Therefore, a 11-digit code will be printed as UPC (as
+ well as 6-digit, 11+2 and 11+5), a 12-digit (or 7-digit, or
+ 12+2 or 12+5) as EAN13, an ISBN code (with or without hyphens,
+ with or without add-5) will be encoded in its EAN13
+ representation, an even number of digits is encoded using
+ CODE128C and a generic string is encoded using CODE128B. Since
+ code-39 offers a much larger representation for the same
+ text string, code128-b is preferred over code39 for
+ alphanumeric strings.
+
+@item BARCODE_NO_ASCII
+
+ Instructs the engine not to print the ascii string on
+ output. By default the bar code is accompanied with an ascii
+ version of the text it encodes.
+
+@item BARCODE_NO_CHECKSUM
+
+ Instructs the engine not to add the checksum character to the
+ output. Not all the encoding types can drop the checksum;
+ those where the checksum is mandatory (like EAN and UPC)
+ just ignore the flag.
+
+@item BARCODE_OUTPUT_MASK
+
+ The mask is used to extract the output-type identifier from
+ the @i{flags} field.
+
+@item BARCODE_OUT_PS
+@itemx BARCODE_OUT_EPS
+@itemx BARCODE_OUT_PCL
+@itemx BARCODE_OUT_PCL_III
+
+ The currently supported encoding types: full-page postscript
+ and encapsulated postscript; PCL (print command language, for
+ HP printers) and PCL-III (same as PCL, but uses a font not
+ available on older printers).
+
+@item BARCODE_OUT_NOHEADERS
+
+ The flag instructs the printing engine not to print the header
+ and footer part of the file. This makes sense for the
+ postscript engine but might not make sense for other engines;
+ such other engines will silently ignore the flag just like
+ the PCL back-end does.

+%M
+%M The barcode family of library functions is meant to ease
+%M creation of bar-code printouts.
+%M
+%M The information below is extracted from the texinfo file, which is the
+%M preferred source of information.
+
+The functions included in the barcode library are declared in the
+header file @t{barcode.h}. They perform the following tasks:
+
+@table @code
+
+@item struct Barcode_Item *Barcode_Create(char *text);
+ The function creates a new barcode object to deal with a
+ specified text string. It returns NULL in case of failure and
+ a pointer to a barcode data structure in case of success.
+
+@item int Barcode_Delete(struct Barcode_Item *bc);
+ Destroy a barcode object. Always returns 0 (success)
+
+@item int Barcode_Encode(struct Barcode_Item *bc, int flags);
+ Encode the text included in the @i{bc} object. Valid flags are
+ the encoding type (other flags are ignored) and
+ BARCODE_NO_CHECKSUM (other flags are silently ignored); if the
+ flag argument is zero, @t{bc->flags} will apply. The function
+ returns 0 on success and -1 in case of error. After
+ successful termination the data structure will host the
+ description of the bar code and its textual representation,
+ after a failure the @t{error} field will include the reason of
+ the failure.
+
+@item int Barcode_Print(struct Barcode_Item *bc, FILE *f, int flags);
+ Print the bar code described by @t{bc} to the specified file.
+ Valid flags are the output type, @t{BARCODE_NO_ASCII} and
+ @t{BARCODE_OUT_NOHEADERS}, other flags are ignored. If any of
+ these flags is zero, it will be inherited from @t{bc->flags}
+ which therefore takes precedence. The function returns 0 on
+ success and -1 in case of error (with @t{bc->error} set
+ accordingly). In case of success, the bar code is printed to
+ the specified file, which won't be closed after use.
+
+@item int Barcode_Position(struct Barcode_Item *bc, int wid, int hei, int xoff, int yoff, double scalef);
+ The function is a shortcut to assign values to the data
+ structure.
+
+@item int Barcode_Encode_and_Print(char *text, FILE *f, int wid, int hei, int xoff, int yoff, int flags);
+ The function deals with the whole life of the barcode
+ object by calling the other functions; it uses all the specified
+ flags.
+
+@item int Barcode_Version(char *versionname);
+ Returns the current version as an integer number of the form
+ major * 10000 + minor * 100 + release. Therefore, version
+ 1.03.5 will be returned as 10305 and version 0.53 as 5300. If
+ the argument is non-null, it will be used to return the version
+ number as a string. Note that the same information is available from
+ two preprocessor macros: @t{BARCODE_VERSION} (the string) and
+ @t{BARCODE_VERSION_INT} (the integer number).

+@end menu
+
+%--------------------------------------------------------------------------
+@node The Command Line, , The barcode Executable, The barcode Executable
+@section The Command Line
+
+
+@b{barcode} accepts the following options:
+
+@table @code
+
+@item --help or -h
+ Print a usage summary and exit.
+
+@item -i filename
+ Identify a file where strings to be encoded are read from. If
+ missing (and if @t{-b} is not used) it defaults to standard
+ input. Each data line of the input file will be used to create
+ one barcode output.
+
+@item -o filename
+ Output file. It defaults to standard output.
+
+@item -b string
+ Specify a single ``barcode'' string to be encoded.
+ The option can be used multiple times in order to encode
+ multiple strings (this will result in multi-page postscript
+ output or a table of barcodes if @t{-t} is specified). The
+ strings must match the encoding chosen; if it doesn't
+ match the program will print a warning to @t{stderr} and
+ generate ``blank'' output (although not zero-length).
+ Please note that a string including spaces or
+ other special characters must be properly quoted.
+
+@item -e encoding
+ @b{encoding} is the name of the chosen encoding format being
+ used. It defaults to the value of the environment variable
+ @t{BARCODE_ENCODING} or to auto detection if the environment is
+ also unset.
+
+@item -g geometry
+ The geometry argument is of the form ``[@i{<width>} @t{x}
+ @i{<height>}] [@t{+} @i{<xmargin>} @t{+} @i{<ymargin>}]'' (with
+ no intervening spaces). Unspecified margin values will result in
+ no margin; unspecified size results in default size.
+ The specified values represent print points by
+ default, and can be inches, millimeters or other units
+ according to the @t{-u} option or the @t{BARCODE_UNIT}
+ environment variable. The argument is used to place the
+ printout code on the page. Note that an additional white
+ margin of 10 points is added to the printout. If the option is
+ unspecified, @t{BARCODE_GEOMETRY} is looked up in the
+ environment, if missing a default size and no margin (but the
+ default 10 points) are used.
+
+@item -t table-geometry
+ Used to print several barcodes to a single page, this option
+ is meant to be used to print stickers. The argument is of the
+ form ``@i{<columns>} @t{x} @i{<lines>} [@t{+} @i{<leftmargin>}
+ @t{+} @i{<bottommargin>} [@t{-} @i{<rightmargin>} [@t{-}
+ @i{<topmargin>}]]]'' (with no intervening spaces); if missing,
+ the top and right margin will default to be the same as the
+ bottom and left margin. The margins are specified in print
+ points or in the chosen unit (see @t{-u} below). If the
+ option is not specified, @t{BARCODE_TABLE} is looked up in the
+ environment, otherwise no table is printed and each barcode
+ will get its own page. The size (but not the position)
+ of a barcode item within a table can also be selected using
+ @t{-g} (see "geometry" above), without struggling with
+ external and internal margins. I still think management of
+ geometries in a table is suboptimal, but I can't make it
+ better without introducing incompatibilities.
+
+
+@item -m margin(s)
+ Specifies an internal margin for each sticker in the
+ table. The argument is of the form
+ ``@i{<xmargin>}@t{,}@i{<ymargin>}'' and the margin is applied
+ symmetrically to the sticker. If unspecified, the environment
+ variable @t{BARCODE_MARGIN} is used or a default internal
+ margin of 10 points is used.
+
+@item -n
+ ``Numeric'' output: don't print the ASCII form of the code,
+ only the bars.
+
+@item -c
+ No checksum character (for encodings that allow it, like code 39,
+ other codes, like UPC or EAN, ignore this option).
+
+@item -E
+ Encapsulated postscript (default is normal postscript). When
+ the output is generated as EPS only one barcode is encoded.
+
+@item -P
+ PCL output. Please note that the Y direction goes from top
+ to bottom for PCL, and the origin for an image is the top-left
+ corner instead of the bottom-left
+
+@item -p pagesize
+ Specify a non-default page size. The page size can be specified
+ in millimeters, inches or plain numbers (for example: "@t{210x297mm}",
+ "@t{8.5x11in}", "@t{595x842}"). A page specification as numbers
+ will be interpreted according to the current unit specification
+ (see @t{-u} below). If libpaper is available,
+ you can also specify the page size with its name, like "@t{A3}"
+ or "@t{letter}" (libpaper is a standard component of Debian
+ GNU/Linux, but may be missing elsewhere). The default page
+ size is your system-wide default if libpaper is there, A4 otherwise.
+
+@item -u unit
+ Choose the unit used in size specifications. Accepted values
+ are ``mm'', ``cm'', ``in'' and ``pt''. By default, the program
+ will check @t{BARCODE_UNIT} in the environment, and assume
+ points otherwise (this behaviour is compatible with 0.92 and
+ previous versions. If @t{-u} appears more than once, each
+ instance will modified the behaviour for the arguments at its
+ right, as the command line is processes left to right. The
+ program internally works with points, and any size is
+ approximated to the nearest multiple of one point. The @t{-u}
+ option affect @t{-g} (geometry), @t{-t} (table) and @t{-p}
+ (page size).

+%##########################################################################
+@node Supported Encodings, PCL Output, The barcode Executable, Top
+@chapter Supported Encodings
+
+The program encodes text strings passed either on the command line
+(with -b) or retrieved from standard input. The text representation is
+interpreted according to the following rules. When auto-detection
+of the encoding is enabled (i.e, no explicit encoding type is specified),
+the encoding types are scanned to find one that can digest the text string.
+The following list of supported types is sorted in the same order
+the library uses when auto-detecting a suitable encoding for a string.
+
+@table @var
+
+@item EAN
+ The EAN frontend is similar to UPC; it accepts strings of
+ digits, 12 or 7 characters long. Strings of 13 or 8 characters
+ are accepted if the provided checksum digit is correct.
+ I expect most users to feed input without a
+ checksum, though. The add-2 and add-5 extension are accepted for both
+ the EAN-13 and the EAN-8 encodings.
+ The following are example of valid input strings:
+ ``@t{123456789012}'' (EAN-13), ``@t{1234567890128}'' (EAN-13 wih
+ checksum), ``@t{1234567}'' (EAN-8), ``@t{12345670 12345}'' (EAN-8
+ with checksum and add-5),
+ ``@t{123456789012 12}'' (EAN-13 with add-2),
+ ``@t{123456789012 12345}'' (EAN-13 with add-5).
+
+@item UPC
+ The UPC frontend accepts only strings made up of digits (and,
+ if a supplemental encoding is used, a blank to separate it).
+ It accepts strings of 11 or 12 digits (UPC-A) and 6 or 7 or 8
+ digits (UPC-E).
+
+ The 12th digit of UPC-A is the checksum and is added by the
+ library if not specified in the input; if it is specified, it
+ must be the right checksum or the code is rejected as invalid.
+ For UPC-E, 6 digit are considered to be the middle part of the
+ code, a leading 0 is assumed and the checksum is added;
+ 7 digits are either considered the initial part (leading digit
+ 0 or 1, checksum missing) or the final part (checksum specified,
+ leading 0 assumed); 8 digits are considered to be the complete code,
+ with leading 0 or 1 and checksum.
+ For both UPC-A and UPC-E, a trailing string of 2 digits or 5 digits
+ is accepted as well. Therefore, the following are examples
+ of valid strings that can be encoded as UPC:
+ ``@t{01234567890}'' (UPC-A)
+ ``@t{012345678905}'' (UPC-A with checksum), ``@t{012345}''
+ (UPC-E), ``@t{01234567890 12}'' (UPC-A, add-2) and
+ ``@t{01234567890 12345}'' (UPC-A, add-5), ``@t{0123456 12}''
+ (UPC-E, add-2).
+ Please note that when setting @t{BARCODE_ANY} to auto-detect
+ the encoding to be used, 12-digit strings and 7-digit strings
+ will always be identified as EAN. This because I expect most
+ user to provide input without a checksum. If you need to
+ specify UPC-with-checksum as input you must explicitly set
+ @t{BARCODE_UPC} as a flag or use @t{-e upc} on the command line.
+
+@item ISBN
+ ISBN numbers are encoded as EAN-13 symbols, with an optional
+ add-5 trailer. The ISBN frontend of the library accepts real
+ ISBN numbers and deals with any hyphen and, if present, the
+ ISBN checksum character before encoding data. Valid
+ representations for ISBN strings are for example:
+ ``@t{1-56592-292-1}'', ``@t{3-89721-122-X}'' and ``@t{3-89721-122-X
+ 06900}''.
+
+@item code 128-B
+ This encoding can represent all of the printing ASCII
+ characters, from the space (32) to DEL (127). The checksum
+ digit is mandatory in this encoding.
+
+@item code 128-C
+ The ``C'' variation of Code-128 uses Code-128 symbols to
+ represent two digits at a time (Code-128 is made up of 104
+ symbols whose interpretation is controlled by the start symbol
+ being used). Code 128-C is thus the most compact way to
+ represent any even number of digits. The encoder refuses to
+ deal with an odd number of digits because the caller is
+ expected to provide proper padding to an even number of
+ digits. (Since Code-128 includes control symbols to switch
+ charset, it is theoretically possible to represent the odd
+ digit as a Code 128-A or 128-B symbol, but this tool doesn't
+ currently implement this option).
+
+@item code 128 raw
+ Code-128 output represented symbol-by-symbol in the input
+ string. To override part of the problems outlined below in
+ specifying code128 symbols, this pseudo-encoding allows the
+ used to specify a list of code128 symbols separated by
+ spaces. Each symbol is represented by a number in the range
+ 0-105. The list should include the leading character.The
+ checksum and the stop character are automatically added by the
+ library. Most likely this pseudo-encoding will be used with
+ @t{BARCODE_NO_ASCII} and some external program to supply the
+ printed text.
+
+@item code 39
+ The code-39 standard can encode uppercase letters, digits, the
+ blank space, plus, minus, dot, star, dollar, slash, percent.
+ Any string that is only composed of such characters is
+ accepted by the code-39 encoder. To avoid loosing information,
+ the encoder refuses to encode mixed-case strings (a lowercase
+ string is nonetheless accepted as a shortcut, but is encoded
+ as uppercase).
+
+@item interleaved 2 of 5
+ This encoding can only represent an even number of digits
+ (odd digits are represented by bars, and even digits by the
+ interleaving spaces). The name stresses the fact that two
+ of the five items (bars or spaces) allocated to each symbol
+ are wide, while the rest are narrow. The checksum digit is
+ optional (can be disabled via @t{BARCODE_NO_CHECKSUM}).
+ Since the number of digits, including the checksum, must be even,
+ a leading zero is inserted in the string being encoded if needed
+ (this is specifically stated in the specs I have access to).
+
+@item code 128
+ Automatic selection between alphabet A, B and C of the Code-128
+ standard. This encoding can represent all ASCII symbols, from
+ 0 (NUL) to 127 (DEL), as well as four special symbols, named
+ F1, F2, F3, F4. The set of symbols available in this encoding
+ is not easily represented as input to the @i{barcode} library,
+ so the following convention is used. In the input string,
+ which is a C-language null-terminated string, the NUL char
+ is represented by the value 128 (0x80, 0200) and the F1-F4 characters
+ are represented by the values 193-196 (0xc1-0xc4, 0301-0304).
+ The values have been chosen to ease their representation as
+ escape sequences.
+
+ Since the shell doesn't seem to interpret escape sequences on the
+ command line, the "-b" option cannot be easily used to designate
+ the strings to be encoded. As a workaround you can resort
+ to the command @t{echo}, either within back-ticks or used
+ separately to create a file that is then fed to the standard-input
+ of @i{barcode} -- assuming your @t{echo} command processes escape
+ sequences. The newline character is especially though to encode
+ (but not impossible unless you use a @t{csh} variant.
+
+ These problems only apply to the command-line tool; the use of
+ library functions doesn't give any problem. In needed, you can
+ use the ``@i{code 128 raw}'' pseudo-encoding to represent
+ code128 symbols by their numerical value. This encoding is
+ used late in the auto-selection mechanism because (almost) any
+ input string can be represented using code128.
+
+@item Codabar
+ Codabar can encode the ten digits and a few special symbols
+ (minus, plus, dollar, colon, bar, dot). The characters
+ ``@t{A}'', ``@t{B}'', ``@t{C}'' and ``@t{D}'' are used to
+ represent four different start/stop characters. The input
+ string to the barcode library can include the start and stop
+ characters or not include them (in which case ``@t{A}'' is
+ used as start and ``@t{B}'' as stop). Start and stop
+ characters in the input string can be either all lowercase or
+ all uppercase and are always printed as uppercase.
+
+@item Plessey
+ Plessey barcodes can encode all the hexadecimal
+ digits. Alphabetic digits in the input string must either be
+ all lowercase or all uppercase. The output text is always
+ uppercase.
+
+@item MSI
+ MSI can only encode the decimal digits. While the standard
+ specifies either one or two check digits, the current
+ implementation in this library only generates one check digit.
+
+@item code 93
+ The code-93 standard can natively encode 48 different characters,
+ including uppercase letters, digits, the blank space, plus, minus,
+ dot, star, dollar, slash, percent, as well as five special
+ characters: a start/stop delimiter and four "shift characters" used
+ for extended encoding. Using this "extended encoding" method, any
+ standard 7-bit ASCII character can be encoded, but it takes up two
+ symbol lengths in barcode if the character is not natively supported
+ (one of the 48).
+ The encoder here fully implements the code 93 encoding standard.
+ Any characters natively supported (A-Z, 0-9, ".+-/$&%") will be
+ encoded as such - for any other characters (such as lower case
+ letters, brackets, parentheses, etc.), the encoder will revert
+ to extended encoding.
+ As a note, the option to exclude the checksum will eliminate the
+ two modulo-47 checksums (called C and K) from the barcode, but this
+ probably will make it unreadable by 99% of all scanning systems.
+ These checksums are specified to be used at the firmware level,
+ and their absence will be interpreted as an invalid barcode.

+%M .SH PCL OUTPUT

+%##########################################################################
+@node PCL Output, Bugs and Pending Issues, Supported Encodings, Top
+@chapter PCL Output
+
+While the default output is Postscript (possibly EPS), and Postscript
+can be post-processed to almost anything, it is sometimes desirable to
+create output directly usable by the specific printer at hand.
+PCL is currently supported as an output format for this reason.
+Please note that the Y coordinate for PCL goes from top to bottom, while
+for Postscript it goes from bottom to top. Consistently, while in
+Postscript you specify the bottom-left corner as origin, for PCL
+you specify the top-left corner.
+
+Barcode output for PCL Printers (HP LaserJet and compatibles),
+was developed using PCL5 Reference manuals from HP.
+that really refers to these printers:
+@itemize @bullet
+
+@item
+LaserJet III, III P, III D, III Si,
+
+@item
+LaserJet 4 family
+
+@item
+LaserJet 5 family
+
+@item
+LaserJet 6 family
+
+@item
+Color LaserJet
+
+@item
+DeskJet 1200 and 1600.
+
+@end itemize
+
+However, barcode printing uses a very small subset of PCL, probably also
+LaserJet II should print it without problem, but the resulting text may
+be horrible.
+
+The only real difference from one printer to another really depends on
+which font are available in the printer, used in printing the label
+associated to the bars (if requested).
+
+Earlier LaserJet supports only bitmaps fonts, so these are not
+"scalable". (Ljet II ?), Also these fonts, when available, have a
+specified direction, and not all of them are available in
+both Portrait and Landscape mode.
+
+From LaserJet 4 series, (except 4L/5L that are entry-level printers),
+Arial scalable font should be available, so it's the "default font"
+used by this program.
+
+LaserJet III series printers (and 4L, 5L), don't feature "Arial" as a
+resident font, so you should use @t{BARCODE_OUT_PCL_III} instead of
+@t{BARCODE_OUT_PCL.}, and font the font used will be "Univers" instead
+of "Arial".
+
+Results on compatible printers, may depend on consistency of
+PCL5 compatibility, in doubt, try BARCODE_OUT_PCL_III
+
+PJL commands are not used here, as it's not very compatible.
+
+
+Tested Printers:
+@itemize @bullet
+@item
+Hp LaserJet 4050
+@item
+Hp LaserJet 2100
+@item
+Epson N-1200 emul PCL

+%##########################################################################
+@node Bugs and Pending Issues, , PCL Output, Top
+@chapter Bugs and Pending Issues.
+
+The current management of borders/margins is far from optimal. The
+``default'' margin applied by the library interferes with the external
+representation, but I feel it is mandatory to avoid creating barcode
+output with no surrounding white space (the problem is especially
+relevant for EPS output).
+
+EAN-128 is not (yet) supported. I plan to implement it pretty soon and
+then bless the package as version 1.0.

+.AT 3
+.SH NAME
+texi2html \- a Texinfo to HTML converter
+.SH SYNOPSIS
+.B texi2html [options] file
+.PP
+.B texi2html -check [-verbose] files
+.SH DESCRIPTION
+.I Texi2html
+converts the given Texinfo file to a set of HTML files. It tries to handle
+most of the Texinfo commands. It creates hypertext links for cross-references,
+footnotes...
+.PP
+It also tries to add links from a reference to its corresponding entry in the
+bibliography (if any). It may also handle a glossary (see the
+.B \-glossary
+option).
+.PP
+.I Texi2html
+creates several files depending on the contents of the Texinfo file and on
+the chosen options (see FILES).
+.PP
+The HTML files created by
+.I texi2html
+are closer to TeX than to Info, that's why
+.I texi2html
+converts @iftex sections and not @ifinfo ones by default. You can reverse
+this with the \-expandinfo option.
+.SH OPTIONS
+.TP 12
+.B \-check
+Check the given file and give the list of all things that may be Texinfo commands.
+This may be used to check the output of
+.I texi2html
+to find the Texinfo commands that have been left in the HTML file.
+.TP
+.B \-expandinfo
+Expand @ifinfo sections, not @iftex ones.
+.TP
+.B \-glossary
+Use the section named 'Glossary' to build a list of terms and put links in the HTML
+document from each term toward its definition.
+.TP
+.B \-invisible \fIname\fP
+Use \fIname\fP to create invisible destination anchors for index links. This is a workaround
+for a known bug of many WWW browsers, including xmosaic.
+.TP
+.B \-I \fIdir\fP
+Look also in \fIdir\fP to find included files.
+.TP
+.B \-menu
+Show the Texinfo menus; by default they are ignored.
+.TP
+.B \-monolithic
+Output only one file, including the table of contents and footnotes.
+.TP
+.B \-number
+Number the sections.
+.TP
+.B \-split_chapter
+Split the output into several HTML files (one per main section:
+chapter, appendix...).
+.TP
+.B \-split_node
+Split the output into several HTML files (one per node).
+.TP
+.B \-usage
+Print usage instructions, listing the current available command-line options.
+.TP
+.B \-verbose
+Give a verbose output. Can be used with the
+.B \-check
+option.
+.PP
+.SH FILES
+By default
+.I texi2html
+creates the following files (foo being the name of the Texinfo file):
+.TP 16
+.B foo_toc.html
+The table of contents.
+.TP
+.B foo.html
+The document's contents.
+.TP
+.B foo_foot.html
+The footnotes (if any).
+.PP
+When used with the
+.B \-split
+option, it creates several files (one per chapter or node), named
+.B foo_n.html
+(n being the indice of the chapter or node), instead of the single
+.B foo.html
+file.
+.PP
+When used with the
+.B \-monolithic
+option, it creates only one file:
+.B foo.html
+.SH VARIABLES
+.I texi2html
+predefines the following variables: \fBhtml\fP, \fBtexi2html\fP.
+.SH ADDITIONAL COMMANDS
+.I texi2html
+implements the following non-Texinfo commands:
+.TP 16
+.B @ifhtml
+This indicates the start of an HTML section, this section will passed through
+without any modofication.
+.TP
+.B @end ifhtml
+This indcates the end of an HTML section.
+.SH VERSION
+This is \fItexi2html\fP version 1.51, 09/10/96.
+.PP
+The latest version of \fItexi2html\fP can be found in WWW, cf. URL
+http://wwwcn.cern.ch/dci/texi2html/

+ * first digit, other codes may have '0' for no-extra-space-needed.
+ *
+ * The next characters are alternating bars and spaces, as multiples
+ * of the base dimension which is 1 unless the code is
+ * rescaled. Rescaling is calculated as the ratio from the requested
+ * width and the calculated width. Digits represent bar/space
+ * dimensions. Lower-case letters represent those bars that should
+ * extend lower than the others: 'a' is equivalent to '1', 'b' is '2' and
+ * so on.
+ *
+ * The "textinfo" string is made up of fields "%lf:%lf:%c" separated by
+ * blank space. The first integer is the x position of the character,
+ * the second is the font size (before rescaling) and the char item is
+ * the charcter to be printed.
+ *
+ * Both the "partial" and "textinfo" strings may include "-" or "+" as
+ * special characters (in "textinfo" the char should be a standalone
+ * word). They state where the text should be printed: below the bars
+ * ("-", default) or above the bars. This is used, for example, to
+ * print the add-5 and add-2 codes to the right of UPC or EAN codes
