/* Mod-Player v1.00 [13-May-1995] for Directory Opus 5.
   By Leo Davidson ("Nudel", P0T-NOoDLE/Gods'Gift Utilities)

   This version is for use with DeliTracker by Peter Kunath & Frank Riffel
   (Delirium Softdesign), but should be easy to adapt to any other player
   with an ARexx port, such as MultiPlayer, EagleTracker, DMP, etc.
   (In fact, a MultiPlayer version should come with this script!).

   If you include the path of a module on the command line, using {f}, only
   this mod will be played. If you omit the {f}, the program will play each
   selected file in the first SOURCE lister, giving you a requester to go to
   the next file or stop playing.

   If the player's ARexx port is not found, the program will be run for
   you (you should edit the path below). This means the script may fail if
   you disable the player's ARexx port, or give an incorrect command line
   to it.
   If the player's ARexx port takes over a minute to appear, an error
   requester will appear on the DOpus screen and the script will quit.
   REMEMBER to add the "RUN" command to the player command line if it does
   not automatically detach from the shell (DeliTracker doesn't)!

   If the player was running to start with, or the user selects
   "Leave Playing", the module will continue playing when the script finishes.
   Otherwise, the player will be quit.
