SLOCCount

SLOCCount: "This is the home page of 'SLOCCount', a set of tools for counting physical Source Lines of Code (SLOC) in a large number of languages of a potentially large set of programs. This suite of tools was used in my papers More than a Gigabuck: Estimating GNU/Linux's Size and Estimating Linux's Size to measure the SLOC of entire GNU/Linux distributions. Others have measured Debian GNU/Linux using this tool suite. SLOCCount runs on GNU/Linux, FreeBSD, Apple Mac OS X, Windows, and hopefully on other systems too. To run on Windows, you have to install Cygwin first to create a Unix-like environment for SLOCCount (Cygwin users: be sure to use ``Unix'' newlines, not ``DOS'' newlines, when you install Cygwin)."
