0.3.2 (to be announced) "probabilistic parity"
----------------------------------------------
+ - new ls option: -lc (list chunk table)
+ - new executable: para_afh, the stand-alone audio file handler tool

---------------------------------------
0.3.1 (2008-02-23) "liquid interaction"
---------------------------------------
be used as a stand-alone command line tool for audio decoding and
volume normalization.

+para_afh
+--------
+
+A small stand-alone program that prints tech info about the given
+audio file to stdout. It can be instructed to print a "chunk table",
+an array of offsets within the audio file. This allows third-party
+streaming software that is unaware of the particular audio format
+to send complete frames in real time. Currently, mp3, ogg vorbis and
+aac are supported.
