If anyone is eager to play with this, I just have put a copy of
ports2bmake.tar.gz in ~sjg/ on freefall.

This contains a script that *should* convert ports to
bmake syntax, while adding a hack to allow older systems to still work.
It will generate a list of all the files it frobs so you can easily
revert them - eg. before updating the tree.

There's a README file in the tarball which hopefully explains all.

Any issues - pls let me know.
