2006-01-03 V2.0.2 

           fix for tabs: don't attempt to export
	   dirtree.RuleSet, since it isn't serialisable

	   added 'doc' directory

2005-12-13 V2.0.1 

           fix for imports: used remote path,
           which was unusable on local O/S

2005-12-11 V2.0.0

           rule filtering for exports, too

2005-06-?? V1.0.0
