Perl interface to the ALSA library

 MIDI::ALSA offers a Perl interface to the ALSA library.
 It also offers some functions to translate events from and to the event
 format used in the MIDI-Perl module (packaged as libmidi-perl).
 .
 Nothing is exported by default, but all the functions and constants can be
 exported, e.g.:
 .
  use MIDI::ALSA(client, connectfrom, connectto, id, input, output);
  use MIDI::ALSA(':CONSTS');
