Some SAGELY advice from a couple of *REALLY* senior Java Engineers I
know, these guys are not only Java people, both of them are VERY GOOD in
more languages you can count on your hands... even if you had an extra
finger on each hand. IMO, these two guys are in the top 0.1% of Software
Engineers in the World, perhaps even 0.01%. But enough on that and how I
came to that conclusion for now.

Here are the rules as far as getting java (mostly any version from 1.2
on) to load all the jars:

     1. If you want any "jar" to be actively used and picked up by java,
        explicitly include it on the classpath
     2. If you have problems with any other jar files, please see rule
        #1

So now you know why I put the shell script in there for all to see.
