EQN symbol libraries

[Damian McGuckin]

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.

Thanks - Damian
