longDescription = ''
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, and my essay Linux Kernel
2.6: It's Worth More! Others have measured Debian GNU/Linux and
the Perl CPAN library using this tool suite.
