# 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 ':'.

$PRGNAM: $PRGNAM (The Emacs Multimedia System)
$PRGNAM: 
$PRGNAM: EMMS is the Emacs Multimedia System. It tries to be a clean and small
$PRGNAM: application to play multimedia files from Emacs using external players.
$PRGNAM: Many of it's ideas are derived from MpthreePlayer , but it tries to be
$PRGNAM: more general and cleaner.
$PRGNAM: The fact that EMMS is based on external players makes it powerful,
$PRGNAM: because it supports all formats that those players support, with no
$PRGNAM: effort from your side.
