Can you rephrase Rods? I don't understand its equivalence in French.

I have created a new Monticello project called LearningArtifacts to host 
   Smalltalk written and Etoys scriptable artifacts. I have pushed an 
optimized version of the FractionBox morph. I will push more artifacts 
from iStoa and other from coming ideas.

To load the Artifact in Etoys-dev, add in the Etoys Monticello(MC) 
browser a HTTP Repository (+Repository), then in the dialog titled 'Http 
repository' paste:

MCHttpRepository
	location: 'http://www.squeaksource.com/LearningArtifacts'
	user: 'etoys'
	password: 'etoys'

You get a new package LearningArtifacts in the left pane of the MC 
browser, select this package, then click the Open button to load a version.
