  Version      : 1.3
  Release Date : 30.03.1994


  Description
  ~~~~~~~~~~~
  ST.svobject is an external Library-Module for the superplay.library V1+.

  It supports reading of ST Modules (SoundTracker V2.4+, ProTracker V2.2a,
  NoiseTracker and compatible Modules).
  xpkmaster.library V2+ is needed to be installed to allow support of
  XPK-packed Modules.


  Remarks
  ~~~~~~~
   - As with other Players, the filename of the Module has to begin
     with "MOD."
   - Only XPK-Packers (PowerPacker, Imploder, xpk????) are supported.
     Any other packer will perhaps cause garbage sound, when it is
     "passed through" XPK-Library.

  Upto V1.2 the main Player Source-Code in Assembler was taken from
  the Public Domain Library "STReplay" by Oliver Wagner, which can be
  found on AmigaLib-Disk #258.
  Oliver said in the Docs to STReplay, that he did not obtain any rights
  to the Source, so I used it for my own purposes.
  Nevertheless I did not just "include" the Source, but made many - more
  or less useful and important - changes to it.

  Since V1.3 the new ProTracker V2.2a Player Routine is used.
  I got it from Gerd Frank (thanks Gerd !) and modified it for my own
  purposes : Some changes had to be made to assemble it with the SAS/C
  ASM V6.5 and to make it living in the multitasking better than before.
  Finally, I had to change and add some more code to create an interface
  to the C-SourceCode of the SPObject's main routines.

  Here's an excerpt from the SourceCode as far as concerning the original
  authors (no special copyright notice was found, so it is perhaps
  Public Domain) :

  * ProTracker2.2a replay routine by Crayon/Noxious. Improved and modified
  * by Teeme of Fist! Unlimited in 1992. Share and enjoy! :)
  * Rewritten for Devpac (slightly..) by CJ.


  History
  ~~~~~~~
  V1.3 (30.03.1994) :

   - replaced old ST Player Routine with new ProTracker V2.2a Player Routine
   - added ST-Module structure definition to Headerfile :
     now it is possible to read the file information without
     playing around with Hex-Offsets.
   - used new STHeader-Definition to print out more information
     about the Module, when calling SPL_FileInfoRequest() :

      - SongName
      - Module-Type : "M.K.", "FLT4", ...
      - Number of Instruments (determined by checking InstrLength)
      - Names of Instruments and hidden strings (even if more than
	the nominal number)
	This was a little bit tricky sometimes, but now it works with
	all modules without crashing the Amiga !
	Enjoy reading the "hidden messages" of ST-Files and find out
	the authors of previous "no name"-modules.
   - replaced SAS/C's sprintf()-routine with own, RawDoFmt()-based one.
     This saves about 1800 Bytes.
   - now using Utility-Library for integer operations (activated
     SAS/C's UTILLIB option) : this increases 68000-codesize a little
     bit, but increases speed on 68020+ systems
     (should also decrease codesize, but does not ...)


  V1.2 (25.02.1994) :

   - fixed small bug in memory management routines


  V1.1 (16.01.1994) :

   - first version
