-#!/bin/sh
-# xdg-terminal-exec is a proposed XDG extension, with example implementation:
-# - <https://github.com/Vladimir-csp/xdg-terminal-exec>
-#
-# its purpose is to allow any program which needs to launch a terminal to do so
-# in a manner which respects user preferences.
-# it aims to be `xdg-open`, but for opening a terminal.
-#
-# a notable user is glib/gio: <repo:gnome/glib:gio/gdesktopappinfo.c>
-# and by extension, Firefox
-#
-# it's not actually packaged for NixOS, nor Alpine, as of 2023/06/29.
-# this script is just a hackier version. it lets me insert my preferences
