I'm trying to use a BaselineOf approach for development, and wanted to know if I got something wrong.

1. Development must be done on the baseline?
2. Configurations must reference a specific point (commit,tag,branch) of the baseline?
3. My dependencies to other projects must be Baselines or Configurations? Why?

BaselineOf: https://github.com/dalehenrich/metacello-work/blob/master/docs/GettingStartedWithGitHub.md

Thanks in advance, Juli��n
