========================================================================

     Autotools appears to have completed successfully. To continue,
     optionally create and cd to a build directory, then run:

             $ $top_srcdir/configure
             $ make

      The testsuite is generated with GNU AutoTest and requires
      GNU make. It is run as follows:

             $ gmake check
