How to get list of plugin commands?

Hi, I am working in Python and I don’t see how to get a list of commands from a given plugin. How do I do that?

from Rhino import PlugIns
plugins = dict(PlugIns.PlugIn.GetInstalledPlugIns())
for guid, name in plugins.iteritems():
    print name
    plugin = PlugIns.PlugIn.Find(guid)
    if plugin:
        commands = plugin.GetCommands()
        for command in commands:
            print '\t'+command.EnglishName
