   Can we get any hints on how to do this?  I am getting better at CRM's 
   syntax but this seems a little too much.  How does one get CRM to decide 
   between the best match amoung several css files?

Well, in the CLASSIFY statement, you can have any number (as long
as it's less than 127) .css files:

   CLASSIFY [:mytext:] (file1.css file2.css file3.css ...) (:stats:)...

Then, get the result by using MATCHs to take apart the :stats:
variable; the second line says:

	Best match to file #somenumber (somefilename.css), weight...

So, just grab the filename (with a MATCH statement- don't forget
to put escaping backslashes in front of the literal parens):

     MATCH [:stats:] ( :: :best_file_name: ) /\(([^\)]+)\)/

and now :best_file_name: is the name of the .css file that matched best.


   Also, I have been monkeying around and was wondering if someone could 
   explain the differences between microgroom and the Arne optimization.

Microgrooming is a way to handle overflowing .css files.  It selectively
(and randomly!) deletes old, mostly-insignificant data to make room for
new, more significant data.

Arne optimization uses the fact that if "foo" is not in the database, then
"foo bar" can't be there either- and skips all of the tests associated with
looking for "foo bar" automagically.  Of course, you can't do this if
microgrooming has thrown away the "foo".

That's why you should either use microgrooming or Arne optimization, 
but never both - and you should stay consistent in which you 
choose to use.
