# Description: Use named bookmarks using symlinks
#
# Dependencies: fzf
#
# Usage:
#   1. Create a $BOOKMARKS_DIR directory
#      By default, $BOOKMARKS_DIR is set to: ${XDG_CACHE_HOME:-$HOME/.cache}/nnn/bookmarks
#
#   2. Create symlinks to directories
#     `cd $BOOKMARKS_DIR`
#     `ln -s /path/to/useful/directory    bookmark_name`
#     `ln -s $XDG_CONFIG_HOME/nnn/plugins nnn_plugins"
#     `ln -s /path/to/documents           docs`
#     `ln -s /path/to/media               media`
#     `ln -s /path/to/movies              movies`
#
# Bonus tip: Add `$BOOKMARKS_DIR` to your `$CDPATH`
#
# TODO:
#   1. Remove `fzf` dependency
