+# 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.
