The program calculates for each class the following six metrics proposed by Chidamber and Kemerer.\r\n\r\n* WMC: Weighted methods per class\r\n* DIT: Depth of Inheritance Tree\r\n* NOC: Number of Children\r\n* CBO: Coupling between object classes\r\n* RFC: Response for a Class\r\n* LCOM: Lack of cohesion in methods\r\n\r\nIn addition it also calculates for each class\r\n\r\n* Ca: Afferent couplings\r\n* NPM: Number of public methods\r\n\r\nIf you use this tool in your research, please cite the following paper.\r\n\r\nDiomidis Spinellis.
