56 gnulib-tool --extract-include-directive module
57 gnulib-tool --extract-license module
58 gnulib-tool --extract-maintainer module
59 gnulib-tool --extract-tests-module module
62 --list print the available module names
63 --import import the given modules into the current package
64 --create-testdir create a scratch package with the given modules
65 --create-megatestdir create a mega scratch package with the given modules
66 one by one and all together
67 --test test the combination of the given modules
68 (recommended to use CC=\"gcc -Wall\" here)
69 --megatest test the given modules one by one and all together
70 (recommended to use CC=\"gcc -Wall\" here)
71 --extract-description extract the description
72 --extract-filelist extract the list of files
73 --extract-dependencies extract the dependencies
74 --extract-autoconf-snippet extract the snippet for configure.ac
75 --extract-automake-snippet extract the snippet for lib/Makefile.am
76 --extract-include-directive extract the #include directive
77 --extract-license report the license terms of the source files
79 --extract-maintainer report the maintainer(s) inside gnulib
80 --extract-tests-module report the unit test module, if it exists
83 --dir=DIRECTORY specify the target directory
84 For --import, this specifies where your
85 configure.ac can be found. Defaults to current
87 --lib=LIBRARY Specify the library name. Defaults to 'libgnu'.
88 --source-base=DIRECTORY
89 Directory relative --dir where source code is
90 placed (default \"lib\"), for --import.
91 --m4-base=DIRECTORY Directory relative --dir where *.m4 macros are
92 placed (default \"m4\"), for --import.
93 --tests-base=DIRECTORY
94 Directory relative --dir where unit tests are
95 placed (default \"tests\"), for --import.
96 --aux-dir=DIRECTORY Directory relative --dir where auxiliary build
97 tools are placed (default \"build-aux\").
98 --with-tests Include unit tests for the included modules.
99 --avoid=MODULE Avoid including the given MODULE. Useful if you
100 have code that provides equivalent functionality.
101 This option can be repeated.
102 --lgpl Abort if modules aren't available under the LGPL.
103 Also modify license template from GPL to LGPL.
104 --libtool Use libtool rules, for --import.
105 --macro-prefix=PREFIX Specify the prefix of the macros 'gl_EARLY' and
106 'gl_INIT'. Default is 'gl'.
107 --no-changelog don't update or create ChangeLog files
108 --dry-run For --import, only print what would have been done.
109 -s, --symbolic, --symlink Make symbolic links instead of copying files.
