# 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..2.69 and automake-1.11..1.15 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.
