+Console-based visual file manager.
+
+Ranger is a file manager with an ncurses frontend written in Python.
+It is designed to give you a broader overview of the file system by
+displaying previews and backviews, dividing the screen into columns.
+
+The keybindings are similar to those of other console programs like
+vim, mutt or ncmpcpp so the usage will be intuitive and efficient.
