#        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).

# 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.
