# About:
# DIYfetch it the shell script template for writing fetch tool
# utilizing `gum join` command (https://github.com/charmbracelet/gum#join).
#
# This script is written in POSIX-shell for portability
# feel free to switch it to any scripting language that you prefer.
#
# Note:
# When copy ANSI string from random script make sure to replace "\033" and "\e" to ""
# or wrap it in `$(printf '%b' "<ansi_string>")`.
