 ## NOTE:
-hunter uses [ranger's rifle](https://github.com/ranger/ranger/blob/master/ranger/ext/rifle.py) to open files if rifle is in your $PATH. If it can't find rifle it uses xdg-open. It also uses ranger's scope.sh to generate previews for non-text files. A slightly modified version is included in the "extra" directory. Put it in your $PATH somewhere if you want previews for non-text files.

Options can be set like this (default config):
