"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.
"Bosdonnat began tracking line contributions in the middle of
September 2010 with the original 14 contributions being made by
Oracle. Oracle actually contributes code to OpenOffice.org, and
then LibreOffice merges those changes, thus resulting in Oracle's
contributions to the new fork. These 112 contributions have
continued throughout development, but are dwarfed by the
contributions of new developers."
