 manpce is det

Starts the XPCE manual tools by opening a small window.

   77manpce :-
   78    in_pce_thread(send(@manual, expose)).

 manpce(+Spec) is det

Start the XPCE manual tools, opening the manual page for Spec. Spec is translated into an XPCE object using pce_to_method/2. Examples:

?- manpce(window).
?- manpce(point->x).

   93    in_pce_thread(manpce_(Spec)).
