-# Description: Print icons in front of list of directories/files
-
-# Dependencies: awk
-
-# Usage
-#    1. Set colors and/or icons to your liking
-#    2. Pipe any directory listing to iconlookup and it will output prepended icons
-#    3. preview-tui uses the script to prepend icon to directory listings
-#    4. Aditionally you can consider adding it to your PATH and/or FZF_DEFAULT_COMMAND to
-#       make it work with various fzf plugins (make sure you also add --ansi to your FZF_DEFAULT_OPTS)
-
-# Shell: POSIX compliant
