#   Use rofi to pick emoji because that's what this
#   century is about apparently...
#
#   Requirements:
#     rofi, xsel, xdotool, curl, xmllint
#
#   Usage:
#     1. Download all emoji
#        $ rofi-emoji --download
#
#     2. Run it!
#        $ rofi-emoji
#
#   Notes:
#     * You'll need a emoji font like "Noto Emoji" or "EmojiOne".
#     * Confirming an item will automatically paste it WITHOUT
#       writing it to your clipboard.
#     * Ctrl+C will copy it to your clipboard WITHOUT pasting it.
#

# Where to save the emojis file.
