I definitely wouldn't do this in C++. I would probably use Python plus
the roslib.package module.
Such a script is likely to be dangerous -- it requires the assumption
that "trunk" of all packages work together. At least for our code,
that assumption is always false.

It is possible, but IMHO, it's non-trival. There are two issues with
mapping it to the idea of roslocate:
* partial checkouts are only supported in git 1.7+
* the megamanifest code would have to be updated to determine the
correct git parameters for partial checkout
it's not hard, per se, but the git 1.7+ requirement, for example,
limits the audience/value of the command.
