I think it varies by who wrote them.

I believe that one used to define more, but I trimmed it. Didn't rename it
because my attempts to do so count as a delete and a create, and thus blank
the svn history for the file. Dunno why.

I didn't do it. :)
An attempt to avoid namespace pollution, I suppose. On the part of one of the
committers.

Not really.

That's sneaky.

This we have a convention for. The things that start with x are "exit or do
blah", so you never have to test for errors when you call one. It either
succeeds or exits the program with an error message.

Actually, the best way to learn TFS is to document TFS. We could use a
libbb.html somewhere...
