Is there a way to make a button that opens a text file?

[Gianluco]

I'm trying to make a button that makes the game open a text file with all the credits for the mod, so the user doesn't have to go to the mod's folder to open it, is there a way to do it? Maybe with MENUDEF?

This is a copy of my MENUDEF from Dissension.
Feel free to copy and edit as you require.

		StaticPatch 32, 24, "DISSHD"
		Position 97, 72
