 # include files and libraries are.  The caller may set variable JAVA_HOME
 # to specify a Java installation prefix explicitly.

+# Specify one or more of the following components as you call this find module. See example below.

+# ::
+#
+#   Runtime     = User just want to execute some Java byte-compiled
+#   Development = Development tools (java, javac, javah and javadoc), includes Runtime component
+#   IdlJ        = idl compiler for Java
+#   JarSigner   = signer tool for jar
