Andreas Raab uploaded a new version of MonticelloConfigurations to project The Trunk:
http://source.squeak.org/trunk/MonticelloConfigurations-ar.78.mcz

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

Name: MonticelloConfigurations-ar.78
Author: ar
Time: 24 August 2010, 8:07:55.2 pm
UUID: fa7c9f6e-3a07-4140-9fbc-629e26b229c5
Ancestors: MonticelloConfigurations-dtl.77

Add a preference governing whether to automatically load missing (unloaded) packages. By default the setting is true to be able to introduce new required packages in the trunk. Users who want to update in images with some packages unloaded can change the setting but do so at their own risk. You have been warned :-)

  MCMcmUpdater provides utility methods for updating Monticello packages from Monticello configurations.
  
  When Monticello configurations are stored in a repository, MCMcmUpdater acts as an update stream. It first ensures that each configuration map has been loaded in sequence, then updates the last configuration map to the most recent version for each specified package, and finally loads these versions to produce a fully updated configuration. !
