The prepare callback gets the entire entry list.  So when the certain 
conditions that you want met are met, you make the change to the 
template_name variable in the entry in the entry list.

For example, if I want the first entry that is going to be shown to use 
a template story_big_size that I wrote that's just like my story 
template, but the font size is bigger so that the entry is more 
prominent at the top of the page, I'd do something like this:

    def cb_prepare(args):
        # only thing in the args dict is the request object
        request = args["request"]

        # the entry list is in the data section
        data = request.get_data()

        entrylist = data["entry_list"]

        if len(entrylist) > 0:
            first_entry = entrylist[0]
            first_entry["template_name"] = "story_big_size"


Say I only wanted to do this if PyBlosxom is rendering a category index 
and not a specific entry.  I'd do something like this:

    def cb_prepare(args):
        # only thing in the args dict is the request object
        request = args["request"]

        # the entry list is in the data section
        data = request.get_data()

        entrylist = data["entry_list"]

        if data["bl_type"] = "dir" and len(entrylist) > 0:
            first_entry = entrylist[0]
            first_entry["template_name"] = "story_big_size"

Does that make sense?  This kicks off after PyBlosxom has figured out 
what it's rendering, but before it actually gets rendered.
