Converting from v1.0 to v1.5 -

  If you were using version 1.0 of Laston, you must simply install the new
  configuration file format and you're all set.  Also, you can delete the
  LASTON.DAT file for it is no longer used.  Laston now uses two data files
  and to keep them in somewhat organized they are labeled with .001 and .002
  extensions.
