I seem to recall seeing '!' prior to darcs 2.0.  But, surprises like this
are never fun.

Darcs offers XML output for many (most?) commands.  But, I assume you're
mentioning it because the command you want to use doesn't provide xml?  I
never can remember where darcs supports XML and where it doesn't.

But, more than just XML, you could link against the darcs source these days.
 I assume TortoiseDarcs is in C or C++.  All someone needs to do is make an
FFI wrapper around the Haskell code to expose it to C, then you can just
call libHSdarcs as if it were part of Tortoise.  Okay, there are a few other
details, but that's the gist of it.

Which route would you prefer?  Calling libdarcs or reading xml?

Cheers,
Jason
