-# Description: File previewer for kitty term using NNN_FIFO
-#
-# Dependencies:
-#   - kitty (https://sw.kovidgoyal.net/kitty/) with allow_remote_control on
-#   - file
-#   - exa (https://github.com/ogham/exa) (fallback: ls)
-#   - bat (https://github.com/sharkdp/bat) (fallback: cat)
-#   - mediainfo (fallback: file)
-#
-# Usage:
-#   This plugin only works in kitty (https://sw.kovidgoyal.net/kitty/),
-#   and with kitty's 'allow_remote_control' option turned on.
-#   You need to set a NNN_FIFO path and set a key for the plugin,
-#   then start `nnn`:
-#
-#     $ NNN_FIFO=/tmp/nnn.fifo nnn
-#
-#   Then in `nnn`, launch the `preview-kitty` plugin.
-#
-#   If you provide the same NNN_FIFO to all nnn instances, there will be a
-#   single common preview window. If you provide different FIFO path, they
-#   will be independent.
-#
-# Shell: POSIX compliant
-# Authors: Léo Villeveygoux
