Useful GSP Tools

by Donny Thurston

Here I will provide some scripts that can be used in GSP as a shortcut for certain constructions. To use them, simply download the file and, when opened, access the tool in the script menu. If you place this file into your GSP tool folder, then it can be accessed in any GSP document.
