-/**
- * Generate the module config for the boot module with
- * a given set of roots (classes or methods) and exclude list.
- *
- * This tool does method-level dependency analysis starting
- * from the root set and follows references transitively as follows:
- * <ul>
- * <li>For a given class, it will parse the ClassFile to
- *     find its superclass and superinterfaces and also
- *     its static initializer &lt;clinit&gt;.</li>
- * <li>For each method, it will parse its Code attribute
- *     to look for a Methodref, Fieldref, and InterfaceMethodref.
- *     </li>
- * <li>For each Fieldref, it will include the type of
- *     the field in the dependency.</li>
- * <li>For each MethodRef, it will follow all references in
- *     that method.</li>
- * <li>For each InterfaceMethodref, it will follow all references in
- *     that method defined its implementation classes in
- *     the resulting dependency list.</li>
- * </ul>
- *
- * Limitation:
- * <ul>
- * <li>For each Methodref, it only parses the method of
- *     the specified type.  It doesn't analyze the class hierarchy
- *     and follow references of its subclasses since it ends up
- *     pulls in many unnecessary dependencies.  For now,
- *     the list of subclasses and methods need to be listed in
- *     the root set.</li>
- * </ul>
