+ * docproc is a simple preprocessor for the template files
+ * used as placeholders for the kernel internal documentation.
+ * docproc is used for documentation-frontend and
+ * dependency-generator.
+ * The two usages have in common that they require
+ * some knowledge of the .tmpl syntax, therefore they
+ * are kept together.
+ *
+ * documentation-frontend
+ * Scans the template file and call kernel-doc for
+ * all occurrences of ![EIF]file
+ * Beforehand each referenced file is scanned for
+ * any symbols that are exported via these macros:
+ * EXPORT_SYMBOL(), EXPORT_SYMBOL_GPL(), &
+ * EXPORT_SYMBOL_GPL_FUTURE()
+ * This is used to create proper -function and
+ * -nofunction arguments in calls to kernel-doc.
+ * Usage: docproc doc file.tmpl
+ *
+ * dependency-generator:
+ * Scans the template file and list all files
+ * referenced in a format recognized by make.
+ * Usage: docproc depend file.tmpl
+ * Writes dependency information to stdout
+ * in the following format:
+ * file.tmpl src.c src2.c
+ * The filenames are obtained from the following constructs:
+ * !Efilename
+ * !Ifilename
+ * !Dfilename

-/*
- * docproc is a simple preprocessor for the template files
- * used as placeholders for the kernel internal documentation.
- * docproc is used for documentation-frontend and
- * dependency-generator.
- * The two usages have in common that they require
- * some knowledge of the .tmpl syntax, therefore they
- * are kept together.
- *
- * documentation-frontend
- * Scans the template file and call kernel-doc for
- * all occurrences of ![EIF]file
- * Beforehand each referenced file is scanned for
- * any symbols that are exported via these macros:
- * EXPORT_SYMBOL(), EXPORT_SYMBOL_GPL(), &
- * EXPORT_SYMBOL_GPL_FUTURE()
- * This is used to create proper -function and
- * -nofunction arguments in calls to kernel-doc.
- * Usage: docproc doc file.tmpl
- *
- * dependency-generator:
- * Scans the template file and list all files
- * referenced in a format recognized by make.
- * Usage: docproc depend file.tmpl
- * Writes dependency information to stdout
- * in the following format:
- * file.tmpl src.c src2.c
- * The filenames are obtained from the following constructs:
- * !Efilename
- * !Ifilename
- * !Dfilename
- * !Ffilename
- * !Pfilename

-# 18/01/2001 - Cleanups
-# Functions prototyped as foo(void) same as foo()
-# Stop eval'ing where we don't need to.
-# -- huggie@earth.li
-
-# 27/06/2001 - Allowed whitespace after initial "/**" and
-# allowed comments before function declarations.
-# -- Christian Kreibich <ck@whoop.org>
-
-# Still to do:
-# - add perldoc documentation
-# - Look more closely at some of the scarier bits :)
-
-# 26/05/2001 - Support for separate source and object trees.
-# Return error code.
-# Keith Owens <kaos@ocs.com.au>
-
-# 23/09/2001 - Added support for typedefs, structs, enums and unions
-# Support for Context section; can be terminated using empty line
-# Small fixes (like spaces vs. \s in regex)
-# -- Tim Jansen <tim@tjansen.de>
-
-# 25/07/2012 - Added support for HTML5
-# -- Dan Luedtke <mail@danrl.de>

-#
-# This will read a 'c' file and scan for embedded comments in the
-# style of gnome comments (+minor extensions - see below).
-#
-
-# Note: This only supports 'c'.
-
-# usage:
-# kernel-doc [ -docbook | -html | -html5 | -text | -man | -list ]
-# [ -no-doc-sections ]
-# [ -function funcname [ -function funcname ...] ]
-# c file(s)s > outputfile
-# or
-# [ -nofunction funcname [ -function funcname ...] ]
-# c file(s)s > outputfile
-#
-# Set output format using one of -docbook -html -html5 -text or -man.
-# Default is man.
-# The -list format is for internal use by docproc.
-#
-# -no-doc-sections
-# Do not output DOC: sections
-#
-# -function funcname
-# If set, then only generate documentation for the given function(s) or
-# DOC: section titles. All other functions and DOC: sections are ignored.
-#
-# -nofunction funcname
-# If set, then only generate documentation for the other function(s)/DOC:
-# sections. Cannot be used together with -function (yes, that's a bug --
-# perl hackers can fix it 8))
-#
-# c files - list of 'c' files to process
-#
-# All output goes to stdout, with errors to stderr.
-
-#
-# format of comments.
-# In the following table, (...)? signifies optional structure.
-# (...)* signifies 0 or more structure elements
-# /**
-# * function_name(:)? (- short description)?
-# (* @parameterx: (description of parameter x)?)*
-# (* a blank line)?
-# * (Description:)? (Description of function)?
-# * (section header: (section description)? )*
-# (*)?*/
-#
-# So .. the trivial example would be:
-#
-# /**
-# * my_function
-# */
-#
-# If the Description: header tag is omitted, then there must be a blank line
-# after the last parameter specification.
-# e.g.
-# /**
-# * my_function - does my stuff
-# * @my_arg: its mine damnit
-# *
-# * Does my stuff explained.
-# */
-#
-# or, could also use:
-# /**
-# * my_function - does my stuff
-# * @my_arg: its mine damnit
-# * Description: Does my stuff explained.
-# */
-# etc.
-#
-# Besides functions you can also write documentation for structs, unions,
-# enums and typedefs. Instead of the function name you must write the name
-# of the declaration; the struct/union/enum/typedef must always precede
-# the name. Nesting of declarations is not supported.
-# Use the argument mechanism to document members or constants.
-# e.g.
-# /**
-# * struct my_struct - short description
-# * @a: first member
-# * @b: second member
-# *
-# * Longer description
-# */
-# struct my_struct {
-# int a;
-# int b;
-# /* private: */
-# int c;
-# };
-#
-# All descriptions can be multiline, except the short function description.
-#
-# You can also add additional sections. When documenting kernel functions you
-# should document the "Context:" of the function, e.g. whether the functions
-# can be called form interrupts. Unlike other sections you can end it with an
-# empty line.
-# Example-sections should contain the string EXAMPLE so that they are marked
-# appropriately in DocBook.
-#
-# Example:
-# /**
-# * user_function - function that can only be called in user context
-# * @a: some argument
-# * Context: !in_interrupt()
-# *
-# * Some description
-# * Example:
-# * user_function(22);
-# */
-# ...
-#
-#
-# All descriptive text is further processed, scanning for the following special
-# patterns, which are highlighted appropriately.
-#
-# 'funcname()' - function
-# '$ENVVAR' - environmental variable
-# '&struct_name' - name of a structure (up to two words including 'struct')
-# '@parameter' - name of a parameter
-# '%CONST' - name of a constant.
