#   EXCLUDE_FILES:=List of files in SRCS that should be excluded

#   EXTRA_FILES:=List of files in SRCS that should be included regardless of suffix match.

#   JAR:=Jar file to create

#   MANIFEST:=Optional manifest file template.

#   JARMAIN:=Optional main class to add to manifest

#   JARINDEX:=true means generate the index in the jar file.

#   SKIP_METAINF:=Set to prevent contents of an META-INF directory to be automatically

#       added to the archive.

#   EXTRA_MANIFEST_ATTR:=Extra attribute to add to manifest.

#   CHECK_COMPRESS_JAR Check the COMPRESS_JAR variable

#   JAR_CMD:=Optionally override the jar command to use when creating the archive.
