Besides what exists in the old /usr/pub/eqnchar are there any other known libraries of EQN symbols. Does anybody else have their own special library? I use (in my own .eqnrc) define nomem ' \(nm ' and define INF ' { size +4 fat inf } ' The former because there is/was some issue about an undefined troff symbol and the latter because I find EQN's predefined 'inf' a bit thin.
