user_eg3 -- demonstrate calling rbox and qhull from C++.\n\
\n\
user_eg3 is statically linked to reentrant qhull.  If user_eg3\n\
fails immediately, it is probably linked to the non-reentrant qhull.\n\
Try 'user_eg3 rbox qhull \"T1\"'\n\
\n\
  eg-100                       Run the example in qh-code.htm\n\
  rbox \"200 D4\" ...            Generate points from rbox\n\
  qhull \"d p\" ...              Run qhull and produce output\n\
  qhull-cout \"o\" ...           Run qhull and produce output to cout\n\
  qhull \"T1\" ...               Run qhull with level-1 trace to cerr\n\
  facets                       Print facets when done\n\
\n\
For example\n\
  user_eg3 rbox qhull\n\
  user_eg3 rbox qhull d\n\
  user_eg3 rbox \"10 D2\"  \"2 D2\" qhull  \"s p\" facets\n\
