sloc is a simple, do-one-thing-well program to calculate code statistics: the
number of lines in a project, and how much of that is code versus comment.

sloc cannot understand gitignore or hgignore, nor can it distinguish between
"real" source and auto-generated files, so for best results, run it on a fresh
repository with no compilation done.
You can generate JSON output with the -json flag, if that's easy to parse in
the programming/scripting language of your choice.
Install sloc with:
$ go get git.bytbox.net/sloc.git/sloc
For graphing amount of code over time (as revealed by a git or mercurial
repository), a reposloc perl script is provided. This is not installable via
the go tool. Consult the man page for usage information.
