    - #### main

          public static void main(java.lang.String[] args)

      Main entry point.

      Process arguments as would a normal Java program. Also create a new Context and associate it with the current thread. Then set up the execution environment and begin to execute scripts.

    - #### exec

          public static int exec(java.lang.String[] origArgs)

      Execute the given arguments, but don't System.exit at the end.

    - #### getGlobal

          public static Global getGlobal()

    - #### processOptions

          public static java.lang.String[] processOptions(java.lang.String[] args)

      Parse arguments.

    - #### processSource

          public static void processSource(Context cx,
                                           java.lang.String filename)
                                    throws java.io.IOException

      Evaluate JavaScript source.
      Parameters:
