i believe activestate also maintains a javascript client [1]. i'm not sure
how closely that tracks the cloud controller api and if it has other non-cf
foundation extensions that map only to activestate stackato functionality.
we can add this detail to a docs page on docs.cloudfoundry.org and note
which ones are in the cf foundation and which ones are public, but not
foundation projects.
