Setting config values based on the current category

I wanted to have different directories (i.e., categories) show a different 
text banner (like where $blog_description appears) but otherwise keep the 
theme the same between them.  I figured I would write a simple plugin that 
stored a dictionary mapping from directory name to long description 
string.

I did that, and then I realized I needed to figure out the current URL 
requested.  *That*'s where I got stuck.  What's the right way to do that?

I am using the cb_prepare() callback, which gives me an args that 
according to 
http://pyblosxom.sourceforge.net/1.4/manual/dev_architecture.html#cb-prepare 
is only guaranteed to have a request object.  That's another thing - where 
is the request object documented? 
http://pyblosxom.sourceforge.net/1.4/api/Pyblosxom.pyblosxom.Request-class.html 
documents it in some fashion but doesn't really list all the attributes it 
should have, I think.  I don't think I should be looking at the HTTP 
dictionary's contents for this; I would guess there's some more pyblosxomy 
place to look.  I figure cb_prepare() is early enough so that I can insert 
values into the configuration dictionary and create variables for use in 
the flavour.

Thanks!  I'm still fairly green as far as customizing pyblosxom despite my 
on-and-off activity on this list.
