   2 # Convenience script for regenerating all autogeneratable files that are
   3 # omitted from the version control repository. In particular, this script
   4 # also regenerates all aclocal.m4, config.h.in, Makefile.in, configure files
   5 # with new versions of autoconf or automake.
   6 #
   7 # This script requires autoconf-2.63..2.68 and automake-1.11 in the PATH.
   8 # If the option --skip-gnulib is not given, it also requires either
   9 #   - the GNULIB_TOOL environment variable pointing to the gnulib-tool script
  10 #     in a gnulib checkout, or
  11 #   - an internet connection.
