Yes ... and the question for the project spec is whether or not you want 
to reference a local git clone or the github project ... I recommend 
that any project that you are using should be cloned locally so that you 
can insulate yourself from network outages as well as make it very easy 
to make changes, fix bugs and share those changes with the community if 
you have a local clone ...

You _can_ create a configuration-based project spec if you want ...

I'm not quite sure that I know what you are asking here. What does your 
existing configuration look like?

There are ways to reference a github project without using a baseline, 
but you have multiple options. It looks like the msgpack project has a 
configuration, so there are a couple of  options:

1. clone the msgpack project to GsDevKit where the GemStone-specific 
mods can be made on a gs_master branch, which would include adding a 
baseline for GemStone only
2. clone the msgpack project to GsDevKit and add a platform-specific 
packages to isolate the GemStone-specific mods from the squeak/pharo 
mods and update the configuration ... optionally add a baseline as well 
... with this option we could submit a pull request to Mushashi's repo 
with your changes.

After looking at Mushashi's repo, I see that he is using the FileTree 
implementation .... Cypress is an umbrella term for the family of 
disk-based formats for storing Smalltalk source. fileTree is a specific 
implementation of the Cypress format for Pharo, Squeak and GemStone. 
There are other implementations floating around with different names ...

When we pick the final msgpack option we define (an publish) a project 
spec for msgpack.
