A new version of System was added to project The Inbox:
http://source.squeak.org/inbox/System-fbs.532.mcz

==================== Summary ====================

Name: System-fbs.532
Author: fbs
Time: 18 May 2013, 10:58:59.877 pm
UUID: 2455a403-4129-451e-ae74-472a347a791e
Ancestors: System-fbs.531

Remove ScrapsBook classvar from Utilities. Instead, lazily instantiate a ScrapBook instance, and delegate trash behaviour to it.
