-A filter program that converts from stdin and writes to stdout. It
-is completely independent from the rest of paraslash, so it might be
-useful also for different purposes.
+A filter program that converts from stdin and writes to stdout.
+
+para_filter combines several decoders (mp3, oggvorbis, aac, wma),
+a volume normalizer and a cpuple of other filters. New filters can
+be added easily. It is possible to "chain" any number of filters,
+like UNIX pipes.
+
+para_filter does not depend on other parts of paraslash, so it can
+be used as a stand-alone command line tool for audio decoding and
+volume normalization.

+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 or to write the content of
+the audio file in complete chunks 'just in time'.
