[commits at source.squeak.org]

Eliot Miranda uploaded a new version of VMMaker to project VM Maker:
http://source.squeak.org/VMMaker/VMMaker.oscog-eem.244.mcz

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

Name: VMMaker.oscog-eem.244
Author: eem

UUID: c9625bb4-bc55-4b75-942c-084c12ea9648
Ancestors: VMMaker.oscog-eem.243

Restore Cogit wanting COGMTVM to be determined on
command line.  Probably broke in VMMaker.oscog-eem.218
