+MP3 library
+-----------
+Version 0.2
+
+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.
+
+comiled and tested only on Solaris 2.6
+main.c contains a simple demo application for library.
+
+COPYING: you may use this source under GPL terms!
+
+PLEASE NOTE: This software may contain patented alogrithm (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:
+ Maybe I change the copyright policy (ie some kind of more free BSD licencse).
+ Please consider this when sending patches/changes.
+ I also want to have the freedom to sell the code to companies that
+ can not use the code under GPL. So, if you send me significant patches,
+ I need your explicit permission to do this. Of course, there will also
+ be the GPLed open source version of the 100% same code.
+ For the case you cannot accept this: the code is GPL, it's your freedom
+ to distribute your changes again under GPL.
+
+FEEDBACK:
+ I'm interessted to here from you, when you use this package as part
+ of another project.
+
