117 --extract-license report the license terms of the source files
119 --extract-maintainer report the maintainer(s) inside gnulib
120 --extract-tests-module report the unit test module, if it exists
123 --dir=DIRECTORY Specify the target directory.
124 For --import, this specifies where your
125 configure.ac can be found. Defaults to current
127 --local-dir=DIRECTORY Specify a local override directory where to look
128 up files before looking in gnulib's directory.
130 Options for --import:
131 --lib=LIBRARY Specify the library name. Defaults to 'libgnu'.
132 --source-base=DIRECTORY
133 Directory relative to --dir where source code is
134 placed (default \"lib\").
135 --m4-base=DIRECTORY Directory relative to --dir where *.m4 macros are
136 placed (default \"m4\").
137 --doc-base=DIRECTORY Directory relative to --dir where doc files are
138 placed (default \"doc\").

140 Directory relative to --dir where unit tests are
141 placed (default \"tests\").
142 --aux-dir=DIRECTORY Directory relative to --dir where auxiliary build
143 tools are placed (default \"build-aux\").
144 --with-tests Include unit tests for the included modules.
145 --avoid=MODULE Avoid including the given MODULE. Useful if you
146 have code that provides equivalent functionality.
147 This option can be repeated.
148 --lgpl Abort if modules aren't available under the LGPL.
149 Also modify license template from GPL to LGPL.
150 --makefile-name=NAME Name of makefile in automake syntax in the
151 source-base and tests-base directories
152 (default \"Makefile.am\").
153 --libtool Use libtool rules.
154 --no-libtool Don't use libtool rules.
155 --macro-prefix=PREFIX Specify the prefix of the macros 'gl_EARLY' and
156 'gl_INIT'. Default is 'gl'.
157 --no-changelog don't update or create ChangeLog files
159 Options for --import and --update:
160 --dry-run For --import, only print what would have been done.
161 -s, --symbolic, --symlink Make symbolic links instead of copying files.
163 Report bugs to <bug-gnulib@gnu.org>."
