Scripts usability: --help option need not start Java
----------------------------------------------------

                 Key: AS7-2276
                 URL: https://issues.jboss.org/browse/AS7-2276
             Project: Application Server 7
          Issue Type: Bug
          Components: Scripts
    Affects Versions: 7.1.0.Alpha1
         Environment: all
            Reporter: Radoslav Husar
            Assignee: Brian Stansberry


It is not necessary to start a JVM to print out raw text on the console. This could be easily handled by the script and print the options in a clean and fast way.
