   4 # and setup. It defines a target called startup that when run will init
   5 # the build directory, generate configure from configure.in, create aclocal
   6 # and has rules to run config.status should one of the .in files change.

   9 #  BUILD - The build director
  10 #  CONVERTED - List of files output by configure $(BUILD) is prepended
  11 #              The caller must provide depends for these files
  12 # It would be a fairly good idea to run this after a cvs checkout.
