[Coin-ipopt] Is there any free AMPL parser can work with IPOPT ?

[Hoxide Ma]

I'm newbie to IPOPT. IPOPT is great. It can work with
AMPL  as a solver. I had try it with AMPL Student
Version , but,Is there any free AMPL parser? 

GNU MathProg Language maybe a "can work" Parser , but
just for linear programming. 

If there is no such parser, why not write a free one?

Another question is , is there any document described
the NL(nonlinear) format used in AMPL?
