Yes, that's probably the best way .. have one module that defines the
lens for such files (say 'single_entry.aug') and then one module for
each type of file you want to separate out; that module would look like

        module Cron_allow_deny
          autoload xfm
          
          let xfm = transform Single_entry.lns 
                       (incl "/etc/cron.allow") . (incl "/etc/cron.deny")
        
Alternatively, you can put everything in one module, and just use a
filter that matches all files of a certain type - though I think it's
cleaner to split along logical lines.
