I agree, but I would not fight for this. I think there is a good argument 
*NOT* to add more if new builtin scripts are added later.

Currently the builtin script can be selected with "-b t" (t for tcpb-like), 
"-b s" (s for simple-update) and "-b se" (se for select-only).

I've reused their current names for the option selector, and it takes the 
first matching prefix.
