=item B<Subclass Archive::Any::Plugin>

 use base 'Archive::Any::Plugin';

=item B<can_handle>

This returns an array of mime types that the plugin can handle.

 sub can_handle {
    return(
           'application/x-tar',
           'application/x-gtar',
           'application/x-gzip',
          );
 }

=item B<files>

Return a list of items inside the archive.

 sub files {
    my( $self, $file ) = @_;
    my $t = Archive::Tar->new( $file );
    return $t->list_files;
 }

=item B<extract>

This method should extract the contents of $file to the current directory.  L<Archive::Any::Plugin> handles negotiating directories for you.

 sub extract {
    my ( $self, $file ) = @_;
 
    my $t = Archive::Tar->new( $file );
    return $t->extract;
 }
