#
# While updating versions of QEMU to 1.0 I got fed up with the
# quilt workflow and just put up a git tree that contains all
# the commits on top of a stable tarball.
#
# When updating this package, just either update the git tree
# below (use rebase!) or change the tree path and use your own
#
# That way we can easily rebase against the next stable release
# when it comes.
