  - verify result: structure, convexity, and point inclusion
    .    - concise list of all options
    -    - one-line description of all options

Output options (subset):
    s    - summary of results (default)
    i    - vertices incident to each facet
    n    - normals with offsets
    p    - vertex coordinates (if 'Qc', includes coplanar points)
           if 'v', Voronoi vertices
    Fp   - halfspace intersections
    Fx   - extreme points (convex hull vertices)
    FA   - compute total area and volu
