                       stdin.wkb)
  -b arg               source for B geometries (WKT, WKB, file, stdin,
                       stdin.wkb)
      --alimit arg     Limit number of A geometries read
  -c, --collect        Collect input into single geometry
  -e, --explode        Explode results into component geometries
  -f, --format arg     Output format (wkt, wkb or txt)
  -h, --help           Print help
  -p, --precision arg  Sets number of decimal places in output coordinates
  -r, --repeat arg     Repeat operation N times
  -t, --time           Print execution time
  -v, --verbose        Verbose output

Notes:
- to use negative numeric op arguments use '--' before the op name
- Negative numeric op arguments can be specified with leading N:  e.g. N-0.1
