autopull.sh

#!/bin/sh
# Convenience script for fetching auxiliary files that are omitted from
# the version control repository of this package.
#
# This script requires either
#   - the GNULIB_SRCDIR environment variable pointing to a gnulib checkout, or
#   - a preceding invocation of './gitsub.sh pull'.
