pmccabe processes the named files, or standard input if none
are named, calculating statistics including McCabe cyclomatic
complexity for each function found. The files are expected to
be either C (ANSI or K&R) or C++.
pmccabe ignores all cpp preprocessor directives - calculating
the complexity of the appearance of the code rather than the
complexity after the preprocessor mangles the code. This is
especially important since simple things like getchar(3)
expand into macros which increase complexity.
