Re: [Fab-user] fab "let" command

[Christian Vest Hansen]

Poof! I just ran into this one.

Consider this a vote to get `let` back at some point.

Until then, this (probably way simplified and naïve) implementation in
my fabfile covers my needs:

def let(**kvargs):
  "Define the provided arbitrary key-value arguments as attributes in env."
  env.update(kvargs)
