[Fab-user] fabric to retrieve information from systems

[Geoff Crompton]

Is it possible for fabric tasks to retrieve information from systems, 
and record the information locally?

So given this simple task:

unames = dict()
def get_uname():
        uname_info = run('/bin/uname -a')
        unames[env.host] = uname_info

How do I make fabric run some python code at the end of it's execution 
to do json.dump(unames)?
