 pengine_rpc(+URL, +Query) is nondet
 pengine_rpc(+URL, +Query, +Options) is nondet
Semantically equivalent to the sequence below, except that the query is executed in (and in the Prolog context of) the pengine server referred to by URL, rather than locally.
  copy_term_nat(Query, Copy),  % attributes are not copied to the server
  call(Copy),			 % executed on server at URL
  Query = Copy.

Valid options are:

chunk(+Integer)
Can be used to reduce the number of network roundtrips being made. See pengine_ask/3.
timeout(+Time)
Wait at most Time seconds for the next event from the server. The default is defined by the setting pengines:time_limit.

Remaining options (except the server option) are passed to pengine_create/1.
