# This makefile is much simpler now that it can use the smart javac wrapper
# for dependency tracking between java packages and incremental compiles.
# It could be even more simple if we added support for incremental jar updates
# directly from the smart javac wrapper.

# Cleaning/copying properties here is not a good solution. The properties
# should be cleaned/copied by a annotation processor in sjavac.

# When you read this source. Remember that $(sort ...) has the side effect
# of removing duplicates. It is actually this side effect that is
# desired whenever sort is used below!
