105 --extract-include-directive extract the #include directive
106 --extract-license report the license terms of the source files
108 --extract-maintainer report the maintainer(s) inside gnulib
109 --extract-tests-module report the unit test module, if it exists
112 --dir=DIRECTORY Specify the target directory.
113 For --import, this specifies where your
114 configure.ac can be found. Defaults to current
116 --local-dir=DIRECTORY Specify a local override directory where to look
117 up files before looking in gnulib's directory.
119 Options for --import:
120 --lib=LIBRARY Specify the library name. Defaults to 'libgnu'.
121 --source-base=DIRECTORY
122 Directory relative to --dir where source code is
123 placed (default \"lib\").
124 --m4-base=DIRECTORY Directory relative to --dir where *.m4 macros are
125 placed (default \"m4\").
126 --doc-base=DIRECTORY Directory relative to --dir where doc files are
127 placed (default \"doc\").
128 --tests-base=DIRECTORY
129 Directory relative to --dir where unit tests are
130 placed (default \"tests\").
131 --aux-dir=DIRECTORY Directory relative to --dir where auxiliary build
132 tools are placed (default \"build-aux\").
133 --with-tests Include unit tests for the included modules.
134 --avoid=MODULE Avoid including the given MODULE. Useful if you
135 have code that provides equivalent functionality.
136 This option can be repeated.
137 --lgpl Abort if modules aren't available under the LGPL.
138 Also modify license template from GPL to LGPL.
139 --makefile-name=NAME Name of makefile in automake syntax in the
140 source-base and tests-base directories
141 (default \"Makefile.am\").
142 --libtool Use libtool rules.
143 --no-libtool Don't use libtool rules.
144 --macro-prefix=PREFIX Specify the prefix of the macros 'gl_EARLY' and
145 'gl_INIT'. Default is 'gl'.
146 --no-changelog don't update or create ChangeLog files
148 Options for --import and --update:
149 --dry-run For --import, only print what would have been done.
150 -s, --symbolic, --symlink Make symbolic links instead of copying files.
152 Report bugs to <bug-gnulib@gnu.org>."
