It was one of the first ideas I was going to add to MC, even just to
have a simple text file explaining what is going on in a repo.
I put a lot of effort into MC to bring the forks together, and make it
maintained and able to move forward with one voice. That failed, so my
motivation for hacking MC anymore is pretty low.

My brain struggles with branches. Perhaps not having them is a good idea?

Its because the rules to load: a package can be blocks executing an
arbitrary script. In normal use the #defaultAction is to process the
given "declared" url to find the package to load.

(Package named: 'SomePackage) what explore.
This could be improved to ask Installer exactly what it will install,
(Package named: 'SomePackage) whatUsingDryRun explore.
Also with DeltaStreams integration with Installer, we might have the
ability to load into a "Delta/SystemEditor" rather than actually in to

Interesting point. I cant think of how to do that. Unless you use sake
to generate a script or a task data scructure, and then you manually
How about merging two dependency trees like so:
(Packages current named: 'Seaside) using: (Packages beta named: 'Pier)

Can never get enough Documentation!

Bob might be able to do something like that in the future. He is sitting
there monitoring a number of repositories, he could periodically process
contributions and derive dependencies because he has some knowledge of
the big picture.
