The problem is that the way that I am calling the Mercurial functions 
now is a complete hack, arrived at mainly by guesswork -- I'm not 
calling the top-level classes, because I don't know how to make them do 
what I want - instead, I'm calling low-level subroutines directly. I'm 
bypassing a whole lot of Mercurial setup code, for example, because I 
have no idea how to make it work. I wasn't able to find any 
documentation for calling Mercurial functions, other than the source 
code comments.

Part of my reason for posting this thing, and the source code, was so 
that the folks who are developing the API could look at my code and see 
what kinds of functions a typical developer might need (all the calls to 
hg are concentrated in the last page of the file, so that should be 
easy.) And given that, perhaps the Mercurial folks could provide some 
sort of documented, externally accessible functions that I could call, 
instead of me poking around randomly in the hg module.

It really "feels" to me like the code that I've written to talk to hg is 
completely wrong, and I have no idea how to make it right.
