WOW. That's awesome. I didn't know about that.

Last thing...instead of havign to load an specific version of CMake by
hand....why not integrate such package under ConfigurationOfCog ?   if you
don't want  to put it in the default group, no problem, but at lesat you can
define a new group like 'VMakerWithCmake' so that we can do:



((Smalltalk at: #ConfigurationOfCog) project
    version: '1.5') load: 'VMakerWithCmake'.

and that's all :)

Another idea is to put in the #description of each version of
ConfigurationOfCog, which is the expected version of git to work. I used to
do this wtih SVN and ConfogurationOfVMMaker.
this way we can map from the other side ;)
even more...in the description you can directlty put which sohuld be the git
command.

cheers
