I had seen that line but didn't take sufficient notice of it. Of course the fact that the plugin comes with *no documentation whatsoever* (not so much as a README file) means that its effect is a matter of guesswork. It's fairly obvious what ".gov" means in the above example, but what does "facebook" mean? Is this a substring match? Against the whole domain or against each component? Is there an #include directive as well? Inquiring minds want to know. poc -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
