	  uuf, everytime <hyperg/utils/types.h> is included
	  (done any time RStrings are defined via str.h),
	  <InterViews/leave-scope> is included because of the
	  UGLY and UNNECCESSARY type boolean and constant nil
	  (it would be pretty and nice if they were part of C++,
	  but they are definitely NOT). {end of religious staff}
	  So, include files that include types.h (via str.h)
	  must not be the last ones if you access Interviews
	  functions (or <InterViews/enter-scope> is appended).

          camera --> Camera


Mon Jan 10 15:30:33 1994  Michael Pichler  (mpichler@fiicmsg01)
