+ * MPGLIB decoder for SDL_sound. This is a very lightweight MP3 decoder,
+ *  which is included with the SDL_sound source, so that it doesn't rely on
+ *  unnecessary external libraries.
+ *
+ * The SMPEG decoder plays back more forms of MPEGs, and may behave better or
+ *  worse under various conditions. mpglib is (apparently) more efficient than
+ *  SMPEG, and, again, doesn't need an external library. You should test both
+ *  decoders and use what you find works best for you.
+ *
+ * mpglib is part of mpg123, which can be found in its original form at:
+ *   http://www.mpg123.de/
+ *
+ * Please see the file COPYING in the source's root directory. The included
+ *  source code for mpglib falls under the LGPL, which is the same license as
+ *  SDL_sound (so you can consider it a single work).

+MP3 library
+-----------
+Version 0.2a
+
+This decoder is a 'light' version (thrown out all unnecessay parts)
+from the mpg123 package. I made this for a company.
+
+Currently only Layer3 is enabled to save some space. Layer1,2 isn't
+tested at all. The interface will not change significantly. 
+A backport to the mpg123 package is planed.
+
+compiled and tested only on Solaris 2.6
+main.c contains a simple demo application for library.
+
+COPYING: you may use this source under LGPL terms! 
+  (Yes, I switched to LGPL for the _mpglib_ part!)
+
+PLEASE NOTE: This software may contain patented algorithms (at least
+  patented in some countries). It may be not allowed to sell/use products
+  based on this source code in these countries. Check this out first!
+
+COPYRIGHT of MP3 music:
+  Please note, that the duplicating of copyrighted music without explicit
+  permission violates the rights of the owner.
+
+SENDING PATCHES:
+  The current version is under LGPL. Please consider this when sending patches or 
+  changes. I also want to have the freedom to sell the code to companies that
+  cannot or do not want to use the code under LGPL. So, if you send me 
+  significant patches, I need your explicit permission to do this. Of course, 
+  there will always be the LGPLed open source version of the 100% same code.
+  In the case you cannot accept this: the code is free, it's your freedom 
+  to distribute your changes again under LGPL. 
+
+FEEDBACK:
+  I'm interessted to here from you, when you use this package as part
+  of another project.
