The /INC and /EXC options specify individual library (.LIB), object (.OBJ), and 
application source (.C, .CPP, or .CXX) files

So I would need to produce a call graph of the indiividual modules used in both 
lpx_integer and lpx_simplex calls. The other alternative is to use example 
problems that make the input and output parts of the profile less important.
