Mesa, DRI framework questions..

[Mohan Parthasarathy]

Ah! I took the Mesa tree from mesa3d.org. It looks like i should be taking
it from anongit.freedesktop.org/git/mesa/mesa
(it is mentioned in the Modulardevelopersguide). So, i don't have to go to
mesa3d.org if i am working with the latest xserver ?
