libmad-ocaml-dev 0.5.2-3 (ppc64el binary) in ubuntu mantic

 This OCaml library interfaces the MAD C library to decode MPEG files.
 The MAD library currently only supports the MPEG 1 standard, but fully
 implements all three audio layers (Layer I, Layer II, and Layer III, the
 latter often colloquially known as MP3.)
 .
 MAD has the following special features:
   - 100% fixed-point (integer) computation
   - completely new implementation based on the ISO/IEC 11172-3 standard
   - distributed under the terms of the GNU General Public License (GPL)
 .
 This package contains all the development stuff you need to use ocaml-mad
 in your programs.
