Count lines of code in a project with CLOC

cloc counts blank lines, comment lines, and physical lines of source code in many programming languages. It is written entirely in Perl with no dependencies outside the standard distribution of Perl v5.6 and higher (code from some external modules is embedded within cloc) and so is quite portable.

Works great for comparing two projects. Recently I went through a code refactor on a project and I needed to give some information back to the client. CLOC made it simple to give a report as to the before and after counts. The before was approx 240K lines of code and the after was about 81K with zero changes to functionality.
