Red Piranha

(If you already do this, just say so.) I would love to install this,
despite the relatively-large disk space penalty of its dependencies
(tomcat, etc. -- everything except Java itself) ... but nearly all the
files I would want it to index are either locked up in compressed tarballs
(or other archives), or compressed themselves. Indexing within tarballs
would move this from a wishlist if-it-would-only-just to firmly into the
install-ASAP category.
