Hi Guillermo
I saw your commit and especially your comment
"saving locally first, then remotelly, doesn't simply copy the changes like Mercurial does..."
The way it works with Monticello, compared to Git/Mercurial (remember that Monticello was conceived before/in parallel with such systems...) - the save command in MC always creates a new version of your package in the repository you selected - saving a version on a remote repository also saves a local copy - if you want to save a version first locally, then want to copy it later to another repository, use the "copy" command from the MC browser
Alternatively, the Gofer API provides commands which are closes to Git/Mercurial workflows: push/fetch etc. See http://www.lukas-renggli.ch/blog/gofer
BTW, is the fix complete? Your package only provides a new method FamixReference>>identityInstanceVariables
