Benryves, I'd say that it seems he wants the academic exercise of making a linker, just as I did when I made one despite Brass's built-in one. To this day I maintain that I ran across some bug or other that provided additional motivation to make my own linker, and to this day I cannot remember nor did I write down what it was. Rascherite: I didn't comment the source much because the functionality is obvious to me, and I didn't intend it to be open-source, per se, even though most things in Python are "open source" by default.
