[Couenne] Any program (other than AMPL) to write NL files?

[sguazt]

Hi,

I know this is an already asked question (the last one I found is
http://list.coin-or.org/pipermail/couenne/2011-March/000175.html).
But maybe something new has been released meanwhile.

So, does anyone know a free program for linux for writing NL files?

I've used to use the AMPL student version, but now I have to solve
some problem which is bigger than the student-version limit.

Thank you very much for any help.

Best,

-- Marco
