517        Furthermore, different versions of postgis place the file in
518        slightly different locations or may even use different names.  For
519        instance:

525    
526        To support both versions, we look in both places and return the
527        first one found (looking under contrib first).  
528    
529        Debian (umcoming Etch) can do several version of postgresql
530        and thus has changed the paths. We try one location
531        in datadir2 only for Debian Etch postgresql-8.1.
532    
533        If the file is not found the return value is None.
