+-- statusd for MPD (Music Player Daemon) using a single persistent connection
+--
+-- bugs/requests/comments: Leandro Lucarella <llucax@gmail.com>
+--
+-- Based on statusd_exec.lua from Antti Vähäkotamäki (the async code) and
+-- statusd_mpd.lua from delirium@hackish.org (the mpd glue code).
+--
+-- Usage is self documented in the default settings section. It provides the
+-- same functionality from statusd_mpd.luam from delirium@hackish.org but it
+-- uses a single persistent connection to MPD and does better usage from hints
+-- (the status is "hinted important" when mpd status or volume change (and
+-- optionally, up to important_time seconds from the begining of each song).
