      3 # This script is a quick hack to generate the various floppies in the
      4 # 'installation/floppies' directory. This script cannot be run in the
      5 # build environment, it is provided as a howto.
      6 # When msdos support is added to makefs, it makes sense to provide a
      7 # decent script that can be integrated into the build environment.
