Extracting list of constraints

Hi there, 

This might be a trivial question, but what's the easiest way of extracting a list of "active" constraints from a math program? Essentially I want the list of constraints names in the Math Program Inspector, exported into a text file. 

The reason behind this requirement is that I have two very similar LPs that I want to compare, to identify why they differ.

I've tried: the constraints listing file (too large / complex and some formatting differences make it difficult to DIFF), exporting AllConstraints. What other options are available?

Thanks!
