Perl::Critic::Utils::McCabe - Functions that calculate the McCabe score of source code.
Provides approximations of McCabe scores. The McCabe score of a set of code describes the number of possible paths through it. The functions here approximate the McCabe score by summing the number of conditional statements and operators within a set of code. See http://www.sei.cmu.edu/str/descriptions/cyclomatic_body.html for some discussion about the McCabe number and other complexity metrics.
