#   CLEAN:=.properties means copy and clean all properties file to the corresponding package in BIN.
#   CLEAN_FILES:=myapp/foo/setting.txt means clean this file over to the package myapp/foo
#   SRCZIP:=Create a src.zip based on the found sources and copied files.

#   DISABLE_SJAVAC:=Explicitly disable the use of sjavac for this compilation unit.

#        when the API changes. Implicitly used in sjavac.
