; NSIS2 Script for GTK2-Runtime
; by Alexander Shaduri <ashaduri 'at' gmail.com>.
; modified by Tom Schoonjans <Tom.Schoonjans 'at' gmail.com>
; Compatible with NSIS Unicode 2.45.
; Public Domain

; The naming convention is:
; Product: GTK2-Runtime;
; Directory and package names: gtk2-runtime.
; The reason for this is that when gtk3 comes out, it
; should be installable side by side with this package.
