DESCRIPTION
Net::MPD is designed as a lightweight replacment for Audio::MPD which
depends on Moose and is no longer maintained.
METHODS
connect [$address]
Connect to the MPD running at the given address. Address takes the form
of password@host:port. Both the password and port are optional. If no
password is given, none will be used. If no port is given, the default
(6600) will be used. If no host is given, localhost will be used.
Return a Net::MPD object on success and croaks on failure.
version
Return the API version of the connected MPD server.
update_status
Issue a status command to MPD and stores the results in the local
object. The results are also returned as a hashref.
MPD ATTRIBUTES
Most of the "status" attributes have been written as combined
getter/setter methods. Calling the "update_status" method will update
these values. Only the items marked with an asterisk are writable.

TODO
Command Lists
MPD supports sending batches of commands but that is not yet available
with this API.
Asynchronous IO
Event-based handling of the idle command would make this module more
robust.
BUGS
Idle connections
MPD will close the connection if left idle for too long. This module
will reconnect if it senses that this has occurred, but the first call
after a disconnect will fail and have to be retried. Calling the ping
command periodically will keep the connection open if you do not have
any real commands to issue. Calling the idle command will block until
something interesting happens.
