# Arg 1: Output target name with .jar suffix, like jars/jarfile.jar.

# Arg 2: Java sources list.  We use VPATH and $^ so sources can be

#        relative to $(srcdir) or $(CURDIR).

# Arg 3: List of extra jars to link against.  We do not use VPATH so

#        jars must be relative to $(CURDIR).

# Arg 4: Additional JAVAC_FLAGS.

# Note: Proguard fails when stale .class files corresponding to

# removed inner classes are present in the object directory.  These

# stale class files get packaged into the .jar file, which then gets

# processed by Proguard.  To work around this, we always delete any

# existing jarfile-classes directory and start fresh.
