There is a way to install a fully-functional, latest-greatest, LibreOffice on our Slackware 15.0 computers and use it. The best part is that it's not difficult to do...at least, not now that you have this handy-dandy HOW-TO document to follow.
Cedric Bosdonnat has been tracking contributions to LibreOffice since its announced fork from OpenOffice.org. He uses Git Data Miner to gleen results from the main branch of LibreOffice Git repositories. Git Data Miner is more commonly known as the tool used by Jonathan Corbet in his periodic kernel code reports.
