In order to experiment with Git based repositories, I have loaded the
Tonel package from the github repositories of Jakob Reschke.

	Installer ensureRecentMetacello.
	(Smalltalk classNamed: #Metacello) new
	   repository: 'github://j4yk/tonel:squeak';
	   baseline: 'Tonel';
	   load.

This brings in the FS-AnsiStreams package, which uses traits.

Having traits in Squeak allows me to load this package.
