=head1 NAME

Blosxom plugin: strip_script_tags

=head1 DESCRIPTION

Designed to remove script tags and their contents from posts so that they can be used in syndication feeds without raising an error at feedvalidator.org.

By default, this plugin will be triggered if the flavour being generated is 'rss', but this can be configured.

If you are doing anything else to the HTML in the post bodies (such as escaping it) be sure to run this plugin first.
