Metric	Description
ca	Afferent coupling : Number of classes affected by this class
bugs	Number of estimated bugs by file (Halstead metric)
commw	Comment weight measure the ratio between logical code and comments
cc	Cyclomatic complexity number measures the number of linearly independent paths through a program's source code
