| # 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. |

| # Usage: ./autogen.sh [--skip-gnulib] |

| # Options: |
| # --skip-gnulib Avoid fetching files from Gnulib. |
| # This option is useful |

| # with modifications), or |
| # - as a speedup, if the set of gnulib modules did not |
