 # This file loads certain extensions required by Padrino from ActiveSupport.
 #
-# Why use ActiveSupport and not our own library or extlib?
-#
-# 1) Rewriting custom method extensions required (i.e string inflectors) is not a good use of time.
-# 2) Loading custom method extensions or separate gems would conflict with AS when AR or MM has been loaded.
-# 3) Datamapper 1.0 supports ActiveSupport 3.0 and no longer requires extlib.
