This is a mpega.library clone using the very excellent libmad for
decoding, it looks and behaves just like the original, but with several
benefits offered by libmad...

Why should I use this instead of the original mpega.library I hear you
say? Well, here's a list of reasons:

- Supports 8kHz streams (the original decodes these wrong).

- Supports FreeFormat (upto a whopping 640kbps) streams.

- Supports ReplayGain (stored in LAMEtags).

- Very high quality decoding (better than the FPU version of the original).

- Very low CPU usage (integer original is still faster on 68k though).

- mpega.library is no longer updated (and I haven't been able to get in
touch with Stephane Tavenard for ~2 years (and counting))...

If this doesn't convince you, well, tough, don't use it then! ;)

Changes in this (7th) release:

- Added some more compiler options to squeeze out more speed.
- Fixed cases where buffersize would be wrong for apps that try to reset it to
another value through the hook (this is not recommended however, as I try to
force a recommended minimum (and absolute minimum is 2880 bytes (not counting
freeformat which can be upto 5760 bytes per frame (perhaps even more))))...
- Now preserves A4, might fix some apps.
- Reenabled -fschedule-insns2 for PPC since new asm doesn't trigger bug, gained
whopping 15% speed (with new asm)... ;)
- More compatibility tweaks, hopefully SongPlayer is less fuzzy about files now.
- Updated to libmad 0.15.1 with new IMDCT for Layer3,
should increase speed *and* accuracy! ;)
- Added support for LAMEtag, using ReplayGain info when decoding.

This archive contains 4 different binaries:

mpega.library.040 - 68k version, just rename it to mpega.library.
mpega.library.pup - "fat" PowerUP binary, rename it to mpega.library.
mpega.library.os4 - OS4 binary, rename it to mpega.library.
mpega.library.elf - MorphOS binary, rename it unless you dualboot on CS/BPPC!

You might notice that the following binary is no longer included
(but the sources still support it, if you manage to build it, please tell me):

mpega.library.wos - WarpOS binary, rename it to mpega.library.

..this is because I have been unable to contact the maintainer for quite a
while, and it seems that no-one else is able to produce a working binary,
accounting for the huge delay of this release, sorry... :P
(4 different people have tried, and all have failed .. StormC strikes again!)

If you are still unfortunate enough to be stuck with WarpOS, I suggest you just
use the PowerUP version with the latest ppclibemu, which should work fine.
