autogen.sh

   1 #!/bin/sh
   2 # Convenience script for regenerating all autogeneratable files that are
   3 # omitted from the version control repository. In particular, this script
   4 # also regenerates all aclocal.m4, config.h.in, Makefile.in, configure files
   5 # with new versions of autoconf or automake.
   6 #
   7 # This script requires autoconf-2.63..2.71 and automake-1.11..1.16 in the PATH.
   8 # If not used from a released tarball, it also requires either
   9 #   - the GNULIB_SRCDIR environment variable pointing to a gnulib checkout, or
  10 #   - a preceding invocation of './gitsub.sh pull'.
  11 # It also requires
  12 #   - the gperf program.
