23 # This is a simple-minded script to compare the functions and instructions
24 # listed for two different models in one or more .igen files.
26 # It was intended to be useful to help factor models into common subsets.
30 # * igen include directives are not processed!
32 # * functions and instructions with multiple definitions (e.g., based
33 # on model names) are treated as being different. In other words,
34 # if two models have different functions named 'foo', this
35 # script will say that one has one of the function definitions, and
36 # the other has the other.
