"This is a new beast and off-limits to all but
developers. This is a parallel Mesa repository for developing
Nouveau Gallium3D support, i.e. what you all are eagerly waiting
for: 3D acceleration. The "master" branch has long been untouched,
but like in the upstream, there are the branches "gallium-0.1" and
"gallium-0.2". In the upstream, i.e. the main Mesa repository, the
"gallium-0.2" branch is used to prepare Gallium3D for merging it
into "master" branch. Cleanups and possibly some interface changes
are done there before the merge. Meanwhile, "gallium-0.1" is the
branch where to develop drivers, and it is kept more
stable."
