+CONFIGURE OPTIONS
+
+Regrettably, this section has not been written (yet). See
+"./configure --help" for current list of options. For general
+information about how to use "configure", please read:
+ doc/install/configure
+
+
+USING ENVIRONMENT VARIABLES
+
+The configure script will also use your environmental
+variables for determining compiler/linker options. This can
+be used to manual specify features and compilation options.
+
+NOTE: If you change environment setting, be sure to remove
+ any config.cache before running ./configure.
+
+Supported Environmental Variables
+ CC C compiler (cc, egcc)
+ CFLAGS C flags (-ansi)
+ CPPFLAGS cpp flags (-I/path/include -Ddef)
+ LDFLAGS ld flags (-L/usr/local/lib)
+ LIBS libraries (-llib)
+ PATH command path /usr/local/bin:/usr/bin:/bin
+
+* Including alternative compilers
+ Use the CC environment variable to tell configure to
+ use a specific compiler. For example, to use ecgs
+ instead of the compiler configure choose, use:
+
+ [env] CC=egcc ./configure
+
+ You can also use CC use specific flags with the
+ specified compiler. For example, to require strict
+ ANSI C using the GNU C Compiler, use:
+
+ [env] CC="gcc -ansi -pedantic" ./configure
+
+ (you can use CFLAGS to specify compiler flags)
+
+* Preprocessor Flags
+ You may specify additional preprocessor flags by setting
+ CPPFLAGS. For example, if you would like to use headers
+ installed in /usr/local/include, use:
+
+ [env] CPPFLAGS="-I/usr/local/include" ./configure
+
+ You can also use CPPFLAGS to specify preprocessor macros.
+
+ [env] CPPFLAGS="-D__SPECIAL_FLAG__" ./configure
+
+* Linker Flags
+ You may specify additional linker flags by setting LDFLAGS.
+ For example, if you would like to use libraries installed
+ in /usr/local/lib, use:
+
+ [env] LDFLAGS="-L/usr/local/lib" ./configure
+
+ You can also use CPPFLAGS to specify linker flags:
+
+ [env] LDFLAGS="-Bstatic" ./configure
+
+* Path
+ You may alter your path to affect configure ability to
+ find (or not find) commands. For example, to have configure
+ additionally look in /usr/css/bin for commands, use:
+
+ [env] PATH="/usr/css/bin:$PATH" ./configure
+
