A hastily thrown together sort of revival of the old Ork speak translator that once lived at http://hiddenway.tripod.com/waaagh/,
which is now a dead site, but is archived on the Wayback Machine at https://web.archive.org/web/20130218135549/http://hiddenway.tripod.com/waaagh/
(you can download the Perl module for the translator there, I did not make it). That site used to have a translator like this one but later on the site wasn't able to keep it and so only hosted the module for others to use.
