   4 #               for recreating `configure' from `configure.in'
   5 #
   6 # options:
   7 #       -s srcdir       directory where `configure' resides (defaults to `.')
   8 #       -d outdir       directory where the files should be written (defaults
   9 #                       to "$srcdir")
  10 #       -v              verbose
  11 #       -n              nocreate - don't create the output files
