=head1 DESCRIPTION

    $ mp3find [options] [directory] [<-field> <pattern> [<-field> <pattern> ...]]

The real guts of the operation are in L<MP3::Find>.

=head2 OPTIONS

=over

=item C<-i>

Case insensitive matching.

=item C<-w>

Match only whole words.

=item C<-sort>

Which ID3 fields to sort the results by; separate multiple fields
with commas. The default behavior just returns the filenames in the
order that L<File::Find> finds them.

=item C<-printf>

The output format for each file found. The available format codes are:

    %a - artist
    %t - title
    %b - album
    %n - track number
    %y - year
    %g - genre
    %% - literal '%'

Numeric modifiers may be used; they are interpreted like modifiers to
the C<%s> code in Perl's C<printf> function.

If no C<-printf> option is used, the full path to the file is printed
instead.

=item C<< <-field> <pattern> >>

The fields you are searching on. These are and-ed together. For the list
of recognized fields, see L<MP3::Find>.
