command-line tool should know what version it is about caliper HOT 11 CLOSED

Does this seem important?

it's an interesting idea in case we know some particular version(s) give bad 
results.

personally, i'd be more interested in it automatically recognizing i was out of 
date and suggesting i upgrade. but i'm probably thinking about it wrong; a real 
user should be using your .deb package repository and not have to think about 
such things. i get what i deserve for building from source.

I'd like to see the Subversion revision number in the version string.

That's a little less trivial and foolproof than it sounds (plus there's the 
fact we use perforce, not subversion, for the internal mirror of caliper).  I'm 
sure it can be hacked together but another alternative is to just use whatever 
is supplied to ant -Dversion=xxx.

I don't care if we even just hardcode the version as a constant and update it 
by hand for each release branch or tag... just have to do _something_.

It would presumably become an attribute of the "Environment."

Let's just stick with the hashing bytecode thing instead.
