Ok. I don't understand what you are suggesting. What I am trying to do
is have the layout customize itself based on the project to which it
is assigned. To do this the layout object needs to have access to the
project or the project needs to be able to decorate the layout when it
is assigned.
It may be simpler to describe it in a patch (that is untested and
really just to illustrate an idea)
diff --git a/lib/buildr/core/project.rb b/lib/buildr/core/project.rb
