[commits at source.squeak.org]

Karl Ramberg uploaded a new version of Collections to project Etoys:
http://source.squeak.org/etoys/Collections-kfr.8.mcz

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

Name: Collections-kfr.8
Author: kfr
Time: 4 March 2012, 2:25:22 pm
UUID: 495f8cf3-0787-9441-a5e0-040b750b52c8
Ancestors: Collections-bf.7

Change the bumper that is put out at the front of a .pr file so if it is encountered by an older version of etoys, instead of simply refusing to load, it now describes the problem to the user and gives the option of proceeding anyway. 

Note: also retains the older bumper guard against loading into even older systems. Pre-olpc-era projects can still not be loaded
