Oh...really? Oops. Didn't mean to step on toes. Clearly I didn't remember.

In any case, if you don't mind looking this over, I'd appreciate it. We can chat in person if necessary.

Looks pretty good to me. My one concern is whether there might still be vestigial code hanging out somewhere. Are you confident this is complete, or are there any more checks that can be done to give us that confidence?

I've done a search for graphviz and dot, and those come up empty. However, there are some stragglers for files with .gv extensions. Another change coming.
