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