Re: [Fab-user] functionality suggestions

[Jeff Forcier]

Hi Timothee,

I've just pushed an update (ee9de18) which addresses the sparsity of
intelligence in get()'s implementation. It now only adds the host
suffix if it would operate on >1 host, does both local and remote
tilde expansion, and will also do the right thing instead of
complaining (which was the Paramiko default) when given a local
directory name.

Best,
Jeff
