# ECJ as a bootstrap compiler is a drop-in replacement for Sun's javac. It offers no more
# and no less features.
#
# Since the VM running the compiler has no effect on the produced bytecode this recipe
# uses the jar created by ecj-initial and creates a start script that runs it with a different
# VM.
