## help

```
usage:
  -a  --autism
        sensitivity to outliers
        range: (0,256);     default: 32
  -N  --neighbors
        points to use when sampling
        range: (0,1024);    default: 29
  -r  --radius
        square neighborhood, always odd
        range: (0,32);      default: [n/a]
  -R  --circle-radius
        circle neighborhood radius
        range: (1,128);     default: [n/a]
  -M  --tries
        random points added to candidates
        range: (0,65536);   default: 192
  -p  --polish
        extra iterations
        range: (0,9);       default: 0
  -m  --magic
        magic constant, affects iterations
        range: (0,255);     default: 192
  -s  --scale
        output size multiplier; negative values set width and height
        range: (-8192,32);  default: 1
  -S  --seed
        initial RNG value
        range: (0,);        default: 0 [time(0)]
  {files...}
        image files to open, resynthesize, and save as {filename}.resynth.png
        required            default: [none]
```

apologies for the `radius`, `circle-radius`, and `polish` parameters.
they should be properly described or removed.
