For both breve and push3, and potentially for other in-house projects, I 
think we'll need to come up with some convention for versioning things.
It's not uncommon that we make updates or bugfixes and need to install 
new builds on a daily basis.  At the same time, the new builds are 
potentially unstable or may behave differently, so we'll also want to keep 
official release copies around as well.

I've been doing this with various versions littered around /opt, but I 
figure it would be a good idea to have a more standard/documented 
approach.

Because breve relies on classfiles which change from release to release, 
it's not as simple as just having multiple breve binaries.  So with that 
in mind, I guess one suggestion would be /usr/local/breve/[version] where 
version is one of: current, development, or any other version/snapshot we 
want to keep.  Users could then set their paths and breve environments 
accordingly.

Does that work?
