88 package from the current gnulib
89 --update update the current package, restore files omitted
91 --create-testdir create a scratch package with the given modules

93 one by one and all together
94 --test test the combination of the given modules
95 (recommended to use CC=\"gcc -Wall\" here)
96 --megatest test the given modules one by one and all together
97 (recommended to use CC=\"gcc -Wall\" here)
98 --extract-description extract the description
99 --extract-filelist extract the list of files
100 --extract-dependencies extract the dependencies
101 --extract-autoconf-snippet extract the snippet for configure.ac
102 --extract-automake-snippet extract the snippet for lib/Makefile.am
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 --libtool Use libtool rules.
138 --no-libtool Don't use libtool rules.
139 --macro-prefix=PREFIX Specify the prefix of the macros 'gl_EARLY' and
140 'gl_INIT'. Default is 'gl'.
141 --no-changelog don't update or create ChangeLog files
143 Options for --import and --update:
144 --dry-run For --import, only print what would have been done.
145 -s, --symbolic, --symlink Make symbolic links instead of copying files.
