char qh_promptb[]

Initial value:

"\
    Qf   - partition point to furthest outside facet\n\
    Qg   - only build good facets (needs 'QGn', 'QVn', or 'PdD')\n\
    Qm   - only process points that would increase max_outside\n\
    Qr   - process random outside points instead of furthest ones\n\
    Qs   - search all points for the initial simplex\n\
    Qu   - for 'd' or 'v', compute upper hull without point at-infinity\n\
              returns furthest-site Delaunay triangulation\n\
    Qv   - test vertex neighbors for convexity\n\
    Qx   - exact pre-merges (skips coplanar and angle-coplanar facets)\n\
    Qz   - add point-at-infinity to Delaunay triangulation\n\
    QGn  - good facet if visible from point n, -n for not visible\n\
    QVn  - good facet if it includes point n, -n if not\n\
    Q0   - turn off default premerge with 'C-0'/'Qx'\n\
    Q1     - sort merges by type instead of angle\n\
    Q2   - merge all non-convex at once instead of independent sets\n\
    Q3   - do not merge redundant vertices\n\
    Q4   - avoid old->new merges\n\
    Q5   - do not correct outer planes at end of qhull\n\
    Q6   - do not pre-merge concave or coplanar facets\n\
    Q7   - depth-first processing instead of breadth-first\n\
    Q8   - do not process near-inside points\n\
    Q9   - process furthest of furthest points\n\
    Q10  - no special processing for narrow distributions\n\
    Q11  - copy normals and recompute centrums for tricoplanar facets\n\
