+/**
+ * The interface to rmic back end implementations.  Classes that
+ * implement this interface correspond to the various generation modes
+ * of rmic (JRMP, IIOP, IDL, etc.).
+ *
+ * A Generator instance corresponds to a particular rmic compilation
+ * batch, and its instance state represents the generator-specific
+ * command line options for that batch.  Main will instantiate a
+ * generator class when the command line arguments indicate selection
+ * of the corresponding generation mode.  Main will then invoke the
+ * "parseArgs" method to allow the generator to process any
+ * generator-specific command line options and set its instance state
+ * accordingly.
+ *
+ * WARNING: The contents of this source file are not part of any
+ * supported API.  Code that depends on them does so at its own risk:
+ * they are subject to change or removal without notice.
