# Small note:  we should prob consider using a DRM only tarball, as it will ease
#              some of the overhead on older systems, and will enable us to
#              update DRM if there are fixes not already in XFree86 tarballs ...

# These sources come from one of four places:
#
#   http://www.xfree86.org/~alanh/ -- DRM snapshots, outdated 
#   http://people.debian.org/~daenzer/ -- full tree, often patched but
#	somewhat outdated
#   http://dri.sourceforge.net/snapshots/ -- daily CVS snapshots, lacking
#	gamma and sis
#   http://dri.sourceforge.net CVS -- full tree
#   http://cvs.sourceforge.net/cvstarballs/dri-cvsroot.tar.gz -- backup
#
# We throw all necessary files into one folder and turn that into our tarball.
