+	DO NOT EDIT THIS FILE
+
+	this file is the same for every GUI toolkit plugin
+	when you are making a new GUI toolkit plugin for
+	a specific toolkit, you just need to define these
+	functions.
+
+	for example, in the "gocui" toolkit, the functions
+	below are what triggers the "gocui" GO package
+	to draw labels, buttons, windows, etc
+
+	If you are starting out trying to make a new GUI toolkit,
+	all you have to do is copy this file over. Then
+	work on making these functions. addWidget(), setText(), etc.
+
+	That's it!
