Chris Muller uploaded a new version of Installer-Core to project The Trunk:
http://source.squeak.org/trunk/Installer-Core-cmm.344.mcz

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

Name: Installer-Core-cmm.344
Author: cmm
Time: 5 March 2011, 2:04:43.252 pm
UUID: f838170c-ff2e-4991-a5cd-0a13f93107b0
Ancestors: Installer-Core-mtf.343

- Removed external call to #readableFileNames as part of the effort to allow MC to scale.  This means InstallerMonticello will no longer accept an external detect-block for package versions; just a Package names.
