Source code quality metrics and complexity are measured from the written source code yielding actual measures of your team's performance. Source code metric differentials can be determined between baselines using RSM code differential work files. Source code metrics (SLOC, KSLOC, LLOC) from this tool can provide line of code derived function point metrics.
RSM has been adopted as a corporate standard metrics tool for many Fortune 100 software companies for compliance to ISO9001, CMMI and AS9100. RSM is the best software source code metrics tool for the money to be found anywhere, all at a very cost sensitive price.

I used RSM from M Squared Technologies (www.msquaredtechnologies.com/index.htm) for gathering the numbers here. It's an inexpensive tool that acquires lots of useful metrics from source files. An evaluation version limited to 20 files is free. It's fast (except on insanely huge code basis like Linux) and easy to use with practically no learning curve. Highly recommended.
RSM is featured in the new Book "Corporate Software Project Management" by Guy W. Lecky-Thompson. Read about how our tool is used in the corporate setting to yield software quality and source code metrics bringing statistical process control to your project.
