=head1 NAME

File::Find::Rule::MMagic - rule to match on mime types

=head1 SYNOPSIS

 use File::Find::Rule::MMagic;
 my @images = find( file => magic => 'image/*', in => '.' );

=head1 DESCRIPTION

File::Find::Rule::MMagic interfaces File::MMagic to File::Find::Rule
enabling you to find files based upon their mime type.  Text::Glob
is used so that the patter may be a simple globbing pattern.

=head2 ->magic( @patterns )

Match only things with the mime types specified by @patterns.  The
specification can be a glob pattern, as provided by L<Text::Glob>.
