Description: lightweight ncurses audio player
 C* Music Player is a modular and very configurable ncurses-based audio player.
 It has some interesting features like configurable colorscheme, mp3 and ogg
 streaming, it can be controlled with an UNIX socket, filters, album/artists
 sorting and a vi-like configuration interface.
 .
 It currently supports different input formats:
  - Ogg Vorbis
  - MP3 (with libmad)
  - FLAC
  - Wav
  - Modules (with libmodplug)
  - Musepack
  - AAC
  - Windows Media Audio
