Hi All,

I'm having some trouble debugging my plugin inside the StarCluster
development shell.

I've created a plugin called like so:

    class NfsShares (ClusterSetup):
         Automatically mounts external NFS shares on StarCluster nodes
         def __init__(self, head_ip):
     "AutoMount.__init__ Running AutoMount plugin.")

.. and placed it in the ~/.starcluster/plugins directory and filled in
the config file as described in the documentation here:

I started a cluster okay with:

starcluster start smallcluster

But when I come to test my plugin inside the development shell according
to the following instructions:

   3. Launch the development shell and test your plugin on your small
      test cluster

$ starcluster shell
[~]|1> cluster.run_plugin('myplugin', 'testcluster', cfg)

... I run this command inside the shell:

cluster.run_plugin('automount', 'smallcluster', cfg)

... and get this error message:

AttributeError: 'module' object has no attribute 'run_plugin'

So I tried the cluster.Cluster object since it has the 'run_plugin' method:

cluster.Cluster.run_plugin(cluster.Cluster, 'automount', 'smallcluster',

... but I get this error message:

     TypeError: unbound method run_plugin() must be called with Cluster
instance as first argument (got type instance instead)

Am I going about this the right way?
