DESCRIPTION

       The GNU portability library is a macro system  and  C  declarations  and  definitions  for
       commonly-used  API  elements  and  abstracted  system behaviors. It can be used to improve
       portability and other functionality in your programs.

OPTIONS

       Operation modes:

       --list print the available module names.

       --import
              import the given modules into the current package; if  no  modules  are  specified,
              update the current package from the current gnulib.

       --update
              update the current package, restore files omitted from CVS.

       --create-testdir
              create a scratch package with the given modules.

       --create-megatestdir
              create a mega scratch package with the given modules one by one and all together.

       --test test the combination of the given modules (recommended to use CC="gcc -Wall" here).

       --megatest
              test  the  given  modules  one  by one and all together (recommended to use CC="gcc
              -Wall" here).

       --extract-description
              extract the description.

       --extract-filelist
              extract the list of files.

       --extract-dependencies
              extract the dependencies.

       --extract-autoconf-snippet
              extract the snippet for configure.ac.

       --extract-automake-snippet
              extract the snippet for lib/Makefile.am.

       --extract-include-directive
              extract the #include directive.

       --extract-license
              report the license terms of the source files under lib/.

       --extract-maintainer
              report the maintainer(s) inside gnulib.

       --extract-tests-module
              report the unit test module, if it exists.

       Options:

       --dir=DIRECTORY
              specify the target directory. For --import, this specifies where your  configure.ac
              can be found. Defaults to current directory.

       --lib=LIBRARY
              Specify the library name. Defaults to 'libgnu'.

       --source-base=DIRECTORY
              Directory relative --dir where source code is placed (default "lib"), for --import.

       --m4-base=DIRECTORY
              Directory relative --dir where *.m4 macros are placed (default "m4"), for --import.

       --tests-base=DIRECTORY
              Directory  relative  --dir  where  unit  tests  are  placed  (default "tests"), for
              --import.

       --aux-dir=DIRECTORY
              Directory relative --dir where auxiliary build tools are  placed  (default  "build-
              aux").

       --with-tests
              Include unit tests for the included modules.

       --avoid=MODULE
              Avoid  including the given MODULE. Useful if you have code that provides equivalent
              functionality. This option can be repeated.

       --lgpl Abort if modules aren't available under the LGPL. Also modify license template from
              GPL to LGPL.

       --libtool
              Use libtool rules, for --import.

       --macro-prefix=PREFIX
              Specify the prefix of the macros 'gl_EARLY' and 'gl_INIT'. Default is 'gl'.

       --no-changelog
              don't update or create ChangeLog files.

       --dry-run
              For --import, only print what would have been done.

       -s, --symbolic, --symlink
              Make symbolic links instead of copying files.

       -h, --help
              Show summary of options.
