 Audio file converter.
-
-This script automate conversion between different type of audio formats.
-Conversion can be performed from the following formats:
-
-    - FLAC
-    - MP3
-    - MP4
-    - WAVE
-    - WavePack
-    - Musepack
-    - Ogg Vorbis
-
-Currently supported encoders:
-
-    - Ogg Vorbis
-    - MP3 (lame)
-
-There is an option to set the quality for the encoders - for Ogg files there
-would be used an `-q' option for `oggenc` command, and for the mp3 format,
-`-V` option would be used for `lame` command. Consult corresponding man pages
-for details.
-
-Aim for this script is to produce high quality ogg files out of (preferably)
-lossless formats like FLAC/WAVE/WavePack or small-sized mp3 files out of
-anything. Of course there is no constraints on what source files would be and
-what output format will be, so there is a possibility to create ogg form low
-quality mp3 files, nevertheless it doesn't make any sense :)
