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.
