mprev - reverse the mpd playlist

=head1 SYNOPSIS

mprev [host]

=head1 DESCRIPTION

B<mprev> reverses mpd's playlist. That's all. The currently playing
song doesn't change. The song you heard last will be the next song to
play.

If the hostname is omitted, the MPD_HOST environment variable will be used.
