56 This is the home page of "SLOCCount", a set of tools for
57 counting physical Source Lines of Code (SLOC) in a large number
58 of languages of a potentially large set of programs. This suite
59 of tools was used in my papers More than a Gigabuck: Estimating
60 GNU/Linux's Size and Estimating Linux's Size to measure the SLOC
61 of entire GNU/Linux distributions, and my essay Linux Kernel
62 2.6: It's Worth More! Others have measured Debian GNU/Linux and
63 the Perl CPAN library using this tool suite.
