That does clear quite a few things up. I will probably take the route of
just adding the directories that contain the tool executables to my path.
And I guess I'll just pay attention to which tools are Java based and copy
the executables under the jars directory. Thanks for looking on the wiki
too. If you find (or create) a suitable wiki page sometime soon would you
be so kind as to post a link to it here, for myself and posterity? That
would be great. Thanks for your help!
P.S. Sorry for the 'double post'. I don't use mailing lists often.
