Not a menu, I totally agree (A menu suggests additional functionality - like being able to actually DO something)
Not random, that is version numbers, driver details etc. The "half asked email addresses" (as you call them) are actually what look like source control repository locations (looks like subversion to me) the ####@ appears to be the revision in the repository... i.e. RevisionNumber@RepositoryLocation
Not much use without the repositories though, more of an interesting find like CJ said.
