=head1 VERSION

version 2.003

=head1 SYNOPSIS

    my $item = Audio::MPD::Common::Item->new( %params );

=head1 DESCRIPTION

L<Audio::MPD::Common::Item> is a virtual class representing a generic
item of mpd's collection. It can be either a song, a directory or a playlist.

Depending on the params given to C<new>, it will create and return an
L<Audio::MPD::Common::Item::Song>, an L<Audio::MPD::Common::Item::Directory>
or an L<Audio::MPD::Common::Playlist> object. Currently, the
discrimination is done on the existence of the C<file> key of C<%params>.

=head1 METHODS

=head2 my $item = Audio::MPD::Common::Item->new( %params );

Create and return either an L<Audio::MPD::Common::Item::Song>, an
L<Audio::MPD::Common::Item::Directory> or an L<Audio::MPD::Common::Playlist>
object, depending on the existence of a key C<file>, C<directory> or
C<playlist> (respectively).
