       -E, --exec CODE
	      Provide a snippet of code to evaluate on the command line

EXAMPLES

       Make an API call against an arbitrary endpoint
	      knife exec -E 'api.get("nodes/fluke.localdomain/cookbooks")'
	      => list of cookbooks for the node fluke.localdomain

       Remove the role obsolete from all nodes
	      knife exec -E 'nodes.transform(:all){|n| n.run_list.delete("role[obsolete]")}'

       Generate the expanded run list for hosts in the webserver role
	      knife exec -E 'nodes.find(:roles => "webserver") {|n| n.expand!; n[:recipes]}'
