Making a Python implementation would be a lot more work, and its speed
would be disappointing.  So let's forget about that.

Including ddepcheck.d with Aap sounds like a good solution.  Even better
would be if the D compiler would be able to do this by itself, like gcc
does.  But that's not in our hands.

Please look at the current version in CVS and suggest how ddepcheck.d
can be added and compiled when necessary.  I think it needs to go into
the "tools" directory.
