We've discussed removing a lot of those tools, too. Not breaking
backwards compatibility is probably the only reason they're still there.

In the case at hand, I seem to recall from upthread that we expect
this'd be obsolete in a release or two. If that's true then I think
a para or two of documentation is a better idea than a tool we'll be
essentially condemned to keep maintaining forever.

Perhaps we could whip up such a .BAT file and put it in the docs?
