--extract-maintainer report the maintainer(s) inside gnulib
--extract-tests-module report the unit test module, if it exists
-Options:
+General options:
+ --dir=DIRECTORY Specify the target directory.
+ For --import, this specifies where your
+ configure.ac can be found. Defaults to current
+ directory.
+ --local-dir=DIRECTORY Specify a local override directory where to look
+ up files before looking in gnulib's directory.
+
+Options for --import:
+ --lib=LIBRARY Specify the library name. Defaults to 'libgnu'.
+ --source-base=DIRECTORY
+ Directory relative to --dir where source code is
+ placed (default \"lib\").
+ --m4-base=DIRECTORY Directory relative to --dir where *.m4 macros are
+ placed (default \"m4\").
+ --doc-base=DIRECTORY Directory relative to --dir where doc files are
+ placed (default \"doc\").
+ --tests-base=DIRECTORY
+ Directory relative to --dir where unit tests are
+ placed (default \"tests\").
+ --aux-dir=DIRECTORY Directory relative to --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.
- --dry-run For --import, only print what would have been done.
--lgpl Abort if modules aren't available under the LGPL.
Also modify license template from GPL to LGPL.
- --lib=LIBRARY Specify the library name. Defaults to 'libgnu'.
- --libtool Use libtool rules, for --import.
- --macro-prefix=PREFIX Specify the prefix of the macros gl_EARLY and
- gl_INIT. Default is "gl".
+ --libtool Use libtool rules.
+ --no-libtool Don't use libtool rules.
+ --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
- -s, --symbolic, --symlink Make symbolic links instead of copying files.
- --with-tests Include unit tests for the included modules.
-Directory options:
- --dir=DIRECTORY specify the target directory
- For --import, this specifies where your
- configure.ac can be found. Defaults to current
- directory.
- --aux-dir=DIRECTORY Directory relative to --dir where auxiliary build
- tools are placed (default \"build-aux\").
- --doc-base=DIRECTORY Directory relative to --dir where doc files are
- placed (default \"doc\"), for --import.
- --m4-base=DIRECTORY Directory relative to --dir where *.m4 macros are
- placed (default \"m4\"), for --import.
- --source-base=DIRECTORY Directory relative to --dir where source code is
- placed (default \"lib\"), for --import.
- --tests-base=DIRECTORY Directory relative to --dir where unit tests are
- placed (default \"tests\"), for --import.
+Options for --import and --update:
+ --dry-run For --import, only print what would have been done.
+ -s, --symbolic, --symlink Make symbolic links instead of copying files.
