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