Is there a *reason* you need to know if you're using 1.8.2 instead of
1.8.1 or 1.8.3?  Generally speaking, you want these things to go by
feature not by release number.  For features which are either add-on
patches, or configured at build time, this is particularly important.
Also keep in mind the sun and macintosh versions are yet again different.

The other twist to be very careful of is that since this is client/server,
just because your *client* code is 1.8.2, doesn't mean the *server*
is 1.8.2.  The wire protocol does have a number, and there are provisions
in the protocol that are intended to hide some wire differences.
