  23 # Usage: $progname [options]
  24
  25 # -f      --force            bootstrap even when sources are not from git
  26 # -p ARG  --download-po=ARG  whether to download pofiles [yes]
  27 # -v      --version          print version information
  28 # -h,-?   --help             print short or long help message
  29
  30 # For --download-po, ARG can also be `no' to skip pofile downloads,
  31 # `only' to just update pofiles, or a set of locales to add or update.
  32
  33 # You can also set the following variables to help $progname
  34 # locate the right tools:
  35 #   AUTOPOINT, AUTORECONF, AWK, GNULIB_TOOL, M4, RM, SED, WGET

  37 # This script bootstraps a git or CVS checkout of GNU M4 by correctly calling
  38 # out to parts of the GNU Build Platform.  Currently this requires GNU
  39 # Gettext 0.16 or better, Autoconf 2.60 or better, GNU M4 1.4.x or
  40 # better, a git snapshot of Automake 1.10a or better, a CVS snapshot
  41 # of Libtool 2.1a or better, and the latest git or CVS checkout of Gnulib.
  42 # Libtool must be installed; either with the same --prefix as
  43 # automake, or made accessible to aclocal's search path via
  44 # $AUTOMAKE_prefix/share/aclocal/dirlist.
