# The converter does not currently handle patch conflicts very well.
# When they occur, it reverts *all* changes and moves forward,
# letting the conflict resolving patch fix collisions.
# Unfortunately, non-conflicting changes, like the addition of the
# "c" file in p1.1 patch are reverted too.
# Just to say that manifest not listing "c" here is a bug.
