As I understand it, some of them involve much brute force. Some of them
involve tying things to something topological like an anomaly. The
prettiest way, I think, due to Seiberg, is to take advantage of
holomorphy of the superpotential.

You can see it in http://www.arxiv.org/abs/hep-th/9408013. The review by Seiberg and Intriligator
http://www.arxiv.org/abs/hep-th/9509066 is also nice. Finally, for nonperturbative neatness in
SUSY gauge theories, I always recommend Argyres's notes:
