[Glass] Is there a way of specifying alternate repos in Baselines/Configurations

[Dale Henrichs via Glass]

Jupiter,

Since we're in diametrically opposed time zones here are links to the 
draft of the tODE 0.1.0 release notes[1] and the section on project 
entries[2] ... feedback on the process and documentation are welcome.

We can set up a skype session if that would be more efficient ...

Dale
