I want to have a second set for <%category%> when it builds the categories.

where or what file is <%category%> assigned from ?

So that I can have <%categorycars%> build for the categories and I would place <%if categorycars%><%categorycars%><%endif%> in the cars category I can asign a category template categorycars.html

So when it builds I want to try and have it build in an alphabetical order going across the top of a page like how dmoz has done it in some of there categories.
