How do you invoke this, anways?

Trying
calabash  -s p:load href=http://graph.facebook.com/me transparent-json=true
tells me
Undeclared option specified: transparent-json

Any chance of supporting text/javascript on this, too?
Facebook returns that by default unless I specificy an Accept header of
application/json.
