* If composer tries to install into a non-empty folder, we risk to effectively erase an existing installation.

* sources, and git can not clone a repo into a non-empty folder.
*
* To prevent this, we adopt the following strategy:
* - install in a separate, temporary directory
* - then move over the installed files copying on top of the existing installation
