  26 # Usage: $progname [options]
  27
  28 # -f      --force            bootstrap even when sources are not from CVS
  29 # -p ARG  --download-po=ARG  whether to download pofiles [yes]
  30 # -v      --version          print version information
  31 # -h,-?   --help             print short or long help message
  32
  33 # For --download-po, ARG can also be `no' to skip pofile downloads,
  34 # `only' to just update pofiles, or a set of locales to add or update.
  35
  36 # You can also set the following variables to help $progname
  37 # locate the right tools:
  38 #   AUTOPOINT, AUTORECONF, AWK, GNULIB_TOOL, M4, RM, SED, WGET
  39
  40 # This script bootstraps a CVS checkout of GNU M4 by correctly calling
  41 # out to parts of the GNU Build Platform.  Currently this requires GNU
  42 # Gettext 0.16 or better, Autoconf 2.60 or better, GNU M4 1.4.x or
  43 # better, a CVS snapshot of Automake 1.10a or better, a CVS snapshot
  44 # of Libtool 2.1a or better, and the latest CVS checkout of Gnulib.
  45 # Libtool must be installed; either with the same --prefix as
  46 # automake, or made accessible to aclocal's search path via
  47 # $AUTOMAKE_prefix/share/aclocal/dirlist.
