122 --extract-license report the license terms of the source files
124 --extract-maintainer report the maintainer(s) inside gnulib
125 --extract-tests-module report the unit test module, if it exists
128 --dir=DIRECTORY Specify the target directory.
129 For --import, this specifies where your
130 configure.ac can be found. Defaults to current
132 --local-dir=DIRECTORY Specify a local override directory where to look
133 up files before looking in gnulib's directory.
135 Options for --import:
136 --lib=LIBRARY Specify the library name. Defaults to 'libgnu'.
137 --source-base=DIRECTORY
138 Directory relative to --dir where source code is
139 placed (default \"lib\").
140 --m4-base=DIRECTORY Directory relative to --dir where *.m4 macros are
141 placed (default \"m4\").
142 --doc-base=DIRECTORY Directory relative to --dir where doc files are
143 placed (default \"doc\").
144 --tests-base=DIRECTORY
145 Directory relative to --dir where unit tests are
146 placed (default \"tests\").
147 --aux-dir=DIRECTORY Directory relative to --dir where auxiliary build
148 tools are placed (default \"build-aux\").
149 --with-tests Include unit tests for the included modules.
150 --avoid=MODULE Avoid including the given MODULE. Useful if you
151 have code that provides equivalent functionality.
152 This option can be repeated.
153 --lgpl Abort if modules aren't available under the LGPL.
154 Also modify license template from GPL to LGPL.
155 --makefile-name=NAME Name of makefile in automake syntax in the
156 source-base and tests-base directories
157 (default \"Makefile.am\").
158 --libtool Use libtool rules.
159 --no-libtool Don't use libtool rules.
160 --macro-prefix=PREFIX Specify the prefix of the macros 'gl_EARLY' and
161 'gl_INIT'. Default is 'gl'.
162 --no-changelog don't update or create ChangeLog files
164 Options for --import and --update:
165 --dry-run For --import, only print what would have been done.
166 -s, --symbolic, --symlink Make symbolic links instead of copying files.
167 --local-symlink Make symbolic links instead of copying files, only
168 for files from the local override directory.
