+#    Description:
+#      This file contains make rules for compiling Java code and building jars.
+#
+
+#
+#    Java Rules Usage
+#    ================
+#
+#    Projects wishing to build Java code should include this file at the *end*
+#    of their Makefile.am files. Additionally, projects must declare a set of
+#    automake local dependencies to cause Java code to be compile for standard
+#    targets. E.g.:
+#
+#        include $(abs_top_srcdir)/scripts/make/java.mk
+#
+#        all-local: all-JARS
+#        install-data-local: install-data-JARS
+#        uninstall-local: uninstall-JARS
+#        mostlyclean-local: mostlyclean-local-JARS
+#
+#    Jars to be built must be declared in the JARS variable *before* java.mk is
+#    included, e.g.:
+#
+#        JARS                        = \
+#            SetupPayloadParser.jar    \
+#            $(NULL)
+#
+#    The building of individual jars is controlled by variables that begin
+#    with the name of the jar file.  E.g. SetupPayloadParser_jar_JFLAGS.  These
+#    variable are:
+#
+#    <name>_JAVA_SRCS -- The list of java source files to be compile and
+#        included in the jar. The file paths are relative to the "src"
+#        subdirectory, which by default is located in the same directory as the
+#        Makefile.am.  E.g.:
+#
+#        SetupPayloadParser_jar_JAVA_SRCS                = \
+#            chip/setuppayload/SetupPayloadParser.java     \
+#            chip/setuppayload/SetupPayload.java           \
+#            $(NULL)
+#
+#    <name>_JFLAGS -- Flags to be passed to the Java compiler.
+#
+#    <name>_JAVA_MAIN_CLASS -- Specifies the application entry point class
+#        for the jar.  Must be a fully qualified class name.
+#
+#    <name>_JAVA_CLASSPATHS -- Additional class paths and/or jars to be passed
+#        to the Java compiler.  Multiple entries must be separated by colons.
+#
+#    <name>_JAVA_EXTRA_SRC_DIRS -- Additional directories containing Java source
+#        files that are used to satisfy references during compilation, but are
+#        not included in the compile output.  Multiple entries must be separated
+#        by colons.
+#
+#    <name>_JAVA_NATIVE_LIB -- The name of a native library to be included in a
+#        platform-specific native subdirectory with the jar file.  The name given
+#        must be both a make target, on which the jar will depend, and the name
+#        of a shared-library file located in the .libs subdirectory of the module's
+#        build directory.  This should typically be the name of a libtool .la file
+#        which is built by other rules in the module's Makefile.am.
+#
+#    <name>_JAVA_STRIP_NATIVE_LIB -- Set to "true" to cause the native library to
+#        be stripped before being included in the jar file.
+#
+#    <name>_JAVA_SRC_DIR -- The directory containing the Java source files.
+#        Defaults to the global value $(JAVA_SRC_DIR), which in turn defaults to
+#        the module's "src" directory, i.e. $(srcdir)/src.
+#
+#    <name>_JAVA_BIN_DIR -- The directory into which the compile Java class files.
+#        should be placed. Defaults to the global value $(JAVA_BIN_DIR), which in
+#        turn defaults to the "bin" subdirectory in the module's build directory,
+#        i.e. $(builddir)/bin.
+#
+#    <name>_JAVA_INSTALL_DIR -- The directory into which the generated jar file is
+#        installed.  Defaults to the global value $(JAVA_INSTALL_DIR), which in turn
+#        defaults to $(datadir)/java.
+#
+#    <name>_MAVEN_PROJECT_FILE -- The name of a Maven project file (pom) to be
+#        included in the jar file.  The pom file will be scanned for groupId and
+#        artifactId fields, which will be used to form the path of the pom file
+#        within the jar file; i.e. META-INF/maven/<groupId>/<artifactId>/pom.xml.
