    Usage: grails [mode] <command>

    Where mode is either dev (default), prod, or test and
    command is one of the following:

      deploy   - generates war and deploys to tomcats defined in Config.groovy.   MUST BE RUN in prod mode ONLY!
      list     - lists all the apps deployed in each tomcat defined in Config.groovy.
      undeploy - undeploys omar from eachof the tomcats defined in Config.groovy.

   Caveats:

    When re-deploying to a tomcat where omar already exists.   tomcat will have to be restarted due to JNI  class
    loading issues.  Looking into a better solution for this.


Also,   sped up the scripts execution as there is no need to actually start up the app for the script to run.  Only
read the necessary config files.
