A new rpm appeared in the Fedora development tree yesterday which has to be the largest I've ever seen posted:
openoffice.org-i18n-1.1.2-2.i386.rpm 124807302 July 31, 2004 09:54:00
This is 2/3 larger than the 1.1.1-6 version in FC3t1. If it's not a debug version, it must contain something really huge, like support for every possible character in the UTF-8 specification.
