for what it's worth, i've never really understood the class hierarchy
in the svncpp stuff either. it all seemed pretty arbitrary and didn't
really follow any rhyme or reason as far as i could tell.

that looks pretty much like what i'd envisioned a c++ binding for svn
to look like.

*laugh* i've got similar stuff sitting in a local svn repository from
when i was playing with some c++ bindings for svn. mine never got
further than playing around though. it's definately the way i'd go
with it though.

thanks, i'll take a look at it tomorrow sometime, it sounds promising.
