#6316: optional doctest failure -- surf tests fail since surf isn't included in
sage anymore
-------------------------------+--------------------------------------------
 Reporter:  was                |       Owner:  tbd       
     Type:  defect             |      Status:  new       
 Priority:  major              |   Milestone:  sage-4.0.3
Component:  optional packages  |    Keywords:            
 Reviewer:                     |      Author:            
   Merged:                     |  
-------------------------------+--------------------------------------------
 I think these tests should be removed.  surf isn't in sage, and it isn't
 even an official "optional spkg". It used to be included as a binary.  It
 is mostly pointless now that we have implicit 3d plotting.
