+# Daemonize kitty by launching one hidden instance that new invocations can use
+# to create new OS windows. This makes kitty startup a lot faster since all
+# windows can now share a single CPU process and GPU sprite cache. Additionally
+# allow remote_control over a socket, so that kitty-cwd works.

+# To launch new invocations using the daemon created by this script use:
