97 (recommended to use CC=\"gcc -Wall\" here)
98 --extract-description extract the description
99 --extract-filelist extract the list of files

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