29 # -f --force bootstrap even when sources are not from git
30 # --skip-po skip downloading pofiles
31 # -v --version print version information
32 # -h,-? --help print short or long help message
34 # You can also set the following variables to help $progname
35 # locate the right tools:
36 # AUTOPOINT, AUTORECONF, AWK, CONFIG_SHELL, GNULIB_SRCDIR, LIBTOOLIZE,
39 # This script bootstraps a git or CVS checkout of GNU M4 by correctly calling
40 # out to parts of the GNU Build Platform. Currently this requires GNU
41 # Gettext 0.16 or better, the latest git Autoconf 2.63b-41 or better,
42 # GNU M4 1.4.5 or better, Automake 1.10b or better, Libtool 2.2 or better,
43 # and the latest git or CVS checkout of Gnulib.
44 # Libtool must be installed; either with the same --prefix as
45 # automake, or made accessible to aclocal's search path via
46 # $AUTOMAKE_prefix/share/aclocal/dirlist.
