+// Glide64 - Glide Plugin for Nintendo 64 emulators
+// Project started on December 29th, 2001
+//
+// Authors:
+// Dave2001, original author, founded the project in 2001, left it in 2002
+// Gugaman, joined the project in 2002, left it in 2002
+// Sergey 'Gonetz' Lipski, joined the project in 2002, main author since fall of 2002
+// Hiroshi 'KoolSmoky' Morii, joined the project in 2007
+//
+//****************************************************************
+//
+// To modify Glide64:
+// * Write your name and (optional)email, commented by your work, so I know who did it, and so that you can find which parts you modified when it comes time to send it to me.
+// * Do NOT send me the whole project or file that you modified.  Take out your modified code sections, and tell me where to put them.  If people sent the whole thing, I would have many different versions, but no idea how to combine them all.
