# A simple make file for Peasant Simulator
#
# This make file depends on two environment variables for locating the Closure
# installation. The first is ${CLOSURE_ROOT} which should point to the base of
# the closure library. The base of the closure library contains both a closure/
# and a third_party/ folder.
#
# The second required environment variable is ${CLOSURE_COMPILER} which points
# to a copy of Closure's compiler.jar file.
