# 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..2.71 and automake-1.11..1.16 in the PATH.
# It also requires
# - the gperf program.

# Prerequisite (if not used from a released tarball): either

#
# Usage: ./autogen.sh [--skip-gnulib]
#
# Options:
# --skip-gnulib Avoid fetching files from Gnulib.
# This option is useful
# - when you are working from a released tarball (possibly
# with modifications), or
# - as a speedup, if the set of gnulib modules did not
# change since the last time you ran this script.
