Console File Manager with VI Key Bindings

 Ranger is a console file manager with VI key bindings. It provides a
 minimalistic and nice curses interface with a view on the directory hierarchy.
 It ships with "rifle", a file launcher that is good at automatically finding
 out which program to use for what file type.
