      nsxiv is a fork of now unmaintained sxiv with the purpose of being a
      drop-in replacement of sxiv, maintaining it and adding simple, sensible
      features, like:

      - Basic image operations, e.g. zooming, panning, rotating
      - Customizable key and mouse button mappings (in config.h)
      - Script-ability via key-handler
      - Thumbnail mode: grid of selectable previews of all images
      - Ability to cache thumbnails for fast re-loading
      - Basic support for animated/multi-frame images (GIF/WebP)
      - Display image information in status bar
      - Display image name/path in X title
