NAME
       Perl::Critic::Utils::McCabe - Functions that calculate the McCabe score of source code.

DESCRIPTION
       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://en.wikipedia.org/wiki/Cyclomatic_complexity> for some discussion about the McCabe
       number and other complexity metrics.

INTERFACE SUPPORT
       This is considered to be a public module.  Any changes to its interface will go through a
       deprecation cycle.

IMPORTABLE SUBS
       "calculate_mccabe_of_sub( $sub )"
	   Calculates an approximation of the McCabe number of the code in a PPI::Statement::Sub.

       "calculate_mccabe_of_main( $doc )"
	   Calculates an approximation of the McCabe number of all the code in a
	   PPI::Statement::Document that is not contained in a subroutine.
