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\
