Yea, that's a good point. Scripts come in different flavours: Installer, 
Metacello, MC configurations.

With a variable for FooFooFoo, a list of the projects at 
MetacelloRepository could be loaded with this:

Installer ss
        project: 'MetacelloRepository';
        install: 'FooFooFoo'.
((Smalltalk at: #FooFooFoo) project version: #stable) load.

Executable with a button push from the SM GUI. Perhaps that's a good place to start with SqS.

Thanks,
Chris
