Fluent grid file format converters

I am performing calculations on data provided to me by Fluent 6. For that, I 
need to have some software which is capable of reading in the grid and data
files Fluent produces. While I can write my own code---the format is well
documented---I would like to know whether anyone else has already written 
a program/module (preferably in C) to do that. Any help would be much appre-
ciated.
