## Details

This copies the Juju agent software from the official agent binaries store 
(located at https://streams.canonical.com/juju) into the controller.
It is generally done when the controller is without Internet access.

Instead of the above site, a local directory can be specified as source.
The online store will, of course, need to be contacted at some point to get
the software.
