# Convenience script for regenerating all autogeneratable files that are
# omitted from the version control repository. In particular, this script
# also regenerates all aclocal.m4, config.h.in, Makefile.in, configure files
# with new versions of autoconf or automake.
#
# This script requires autoconf-2.63 and automake-1.11 in the PATH.
# It also requires either
#   - the GNULIB_TOOL environment variable pointing to the gnulib-tool script
#     in a gnulib checkout, or
#   - the git program in the PATH and an internet connection.
# It also requires
#   - the gperf program.
