=head1 NAME

WE_Frontend::Plugin::NullFilter - a sample custom filter

=head1 SYNOPSIS

    # In the calling script (normally already done by WebEditor::OldController)
    my $t = Template->new({PLUGIN_BASE => "WE_Frontend::Plugin"});

    # In the template
    [% USE NullFilter %]
    [% FILTER $NullFilter %]
    ...
    [% END %]
    [% variable | $NullFilter %]

=head1 DESCRIPTION

This filter does nothing, i.e. it copies the input unchanged to the
output. This module serves as a sample filter for own extensions.

=cut

sub filter {
    my($self, $text) = @_;
    # do something interesting with $text
    return $text;
}

1;

__END__
