That sounds great.

It would be nicest is you could indeed make a program (preferably C 
or Perl) to transform the force field files into gromacs format. In the 
not so distant future I will start to transform all these kind of data 
files into XML, but then I will have to convert the old files 
automatically as well. It would be nice if we had some kind of CNS input 
reader that we could hook into this conversion tool, such that we can 
convert future CNS and or AMber force fields into gromacs without 
intermediate steps.

Groeten, David.
