Hmm, yeah. In any case, while looking at this stuff I realized that I
should
take my own suggestion about using SCRIPT_NAME + PATH_INFO in the url
base
block of code. My current method only works for repositories hosted at a
web
server's root...which happens to be what I'm doing (no surprise there),
but is likely not the case for everyone.
