Comment #3 on issue 616 by tudor.gi...@gmail.com: cleaning package cycles http://code.google.com/p/moose-technology/issues/detail?id=616
The problem is that Chef should be an extension, but it is not possible with Pharo because we cannot add a Trait as an extension. So the result is that we merged Chef in Famix-Core, but we put it in a sub category.
However, this breaks the convention of one category per package. So, we should simply move the Traits to Famix-Core until we will get some better support for Trait extensions.
