"baseline" and "version" are Metacello terms. A "baseline" specifies a 
set of packages and their dependencies. A "version" defines which version 
of those packages should be loaded. So this loads the latest version of 
all packages. So this script is the "head" on SqueakMap.

The latest version of the packages can be considered as stable, all tests 
pass. I can create a "version" with these and mark it as stable for 
Squeak 4.2. When this is done, a different script can be added for 4.2 on 
SqueakMap.
