  Joe level format 1 to format 2 converter.
  -----------------------------------------

  Usage: convert <infile> [<outfile>]

  If outfile is not specified, the file is outputted to stdout.

  Converts a Joe level format 1 file to a format 2 file, which is more
compact and actually the internal level format of Joe.
  The format 2 is also slightly crypted, so it's ideal for distributing
your levels (nobody can cheat by editing your level).

  You can put comments after the 'End' line. Don't edit anything above this
line or the program will probably crash.

  Maybe in the future I'll make a multilevel format with a crypted password
system.
