Actually, it was tex.scan, which is a simple ruby command scanning
the string given by the variable tex. I think Kevin by accident
mistyped it. (You can see the revision diff).

What a difference a dot makes, eh?

I like the command too, though I don't really use it much at this
point, (need to open the actual help file most of the times). I wrote
the command originally, and looking at the revision history of the
command would show that it was tex.scan. Does it work as expected if
you make that change? If so, I don't really see the advantage of

I think that's a bit unclear at the moment. Hadley Wickham, I think
did the original import. Then Allan did some cleanup work on it. Then
it stayed dormant for quite some time, until I started using R and
started adding stuff to the bundle. Lately Kevin Ballard was using R
and did some great work on the bundle. And now Hans has sent a lot of
suggestions and improvements to the commands. So in some sense there
is no official maintainer, though I would consider myself one of the
maintainers, unfortunately overwhelmed at the moment with lots of
other work, both textmate and real. If tex.scan instead of texscan
works for you, then we can perhaps leave this command as is for now
(well, with tex.scan instead of texscan).
