# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|'
# on the right side marks the last column you can put a character in.  You must
# make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':' except on otherwise blank lines.

libmad: libmad (high-quality MPEG audio library)
libmad:
libmad: MAD (libmad) is a high-quality MPEG audio decoder.  It currently
libmad: supports MPEG-1 and the MPEG-2 extension to Lower Sampling
libmad: Frequencies, as well as the so-called MPEG 2.5 format.  All three
libmad: audio layers (Layer I, Layer II, and Layer III a.k.a. MP3) are
libmad: fully implemented.  Because MAD provides full 24-bit PCM output,
libmad: applications using MAD are able to produce high quality audio.
libmad: MAD is distributed under the terms of the GPL.

libmad: MAD (libmad) was written by Robert Leslie.
