neo simple X image viewer

 nsxiv (the Neo Simple X Image Viewer) is a fork of the now-unmaintained
 sxiv project, with the purpose of being a drop-in replacement for sxiv,
 maintaining its interface, and adding simple, sensible features. nsxiv aims
 to be easy to modify and customise, and works nicely with tiling window
 managers.

 Features:
