Hi Stuart,

First of all the docs have not yet been updated for the latest github
code and my apologies for this. I've been insanely busy with another
project the last couple months and am just now getting back to sanity.

In any event it appears you're using the latest github code and you've
discovered you need the ClusterManager which is correct. However, your
usage is slightly off (although it works). Doing this completely
manually would involve:

from starcluster import config
from starcluster import cluster
cfg = config.StarClusterConfig()
cm = cluster.ClusterManager(cfg)
cm.run_plugin('automount', 'smallcluster')

BTW if you use "starcluster shell" with the github code you
automatically have a ClusterManager object available to you as the "cm"
variable:

$ starcluster shell
StarCluster - (http://web.mit.edu/starcluster) (v. 0.9999)

Hope that helps,
