Maybe they should be moved to a separate directory (src)?

I seem to remember discussing this once before but I'm not sure why we
didn't include them.  If we do include them, I would want only one
version, so we would replace the scripts with the compiled code.  I
think some people objected to having them be compiled programs instead
of scripts because it made it harder to modify them or see exactly
what they are doing (for example, find how the environment variables
are used).

In any case, I think this is a change that can wait until after 3.0.
