How to install metrics

The metrics software package was born in 2010 out of my frustration about available Open Source metrics packages. There are plenty of them so it is not a problem to find one. But each and every of them has a different focus. Most metrics packages have restrictions towards available metrics and supported languages. Some prominent samples are (CCCC, SLOCCount, PyMetrics, Eclipse-Metrics, Ohcount).
One more thing on metrics. Compared to PyMetrics I changed the SLOC metric a lot. PyMetrics was criticised in the past for its SLOC metric. I simplified to something that I understand as the common denominator for the metric packages mentioned above. This metric counts the lines but excludes empty lines and comments. This is sometimes referred to as the source lines of code (SLOC). In literature this is often also referred as physical lines of code.
Another thing I wanted to mention is that I borrowed the sample programming language files for the test cases from Ohcount and Firefox.
I currently have spent about two weeks working on the metrics package and I already tested it a lot. I compared the metrics results against results extracted from other metrics packages, against values I counted manually, and results from a commercial package (I Understand that I can not revile its name here because its results have been very inaccurate). From the comparison I have the impression that the results of the metrics package are pretty accurate. Nevertheless I will keep the package in alpha state so nobody will jump on it blindly. Please provide feedback if it worked for you. If something does not work as you expected please let me know. In this case it would be brilliant if you could provide a free code sample and the appropriate values in order to reproduce the problem. Please get in touch if you feel that some important feature/metric is missing, too.
