please show example of excluding node_modules

This is NPM this is Node.js, the docs say use a regex to exclude, but what kind of regex? A JS regex?

A nice example would be excluding node_modules when running sloc against an NPM project

I am guessing this is the one:

`sloc -e node_modules .`

but I cannot be certain - in fact I am fairly certain this is not working, my machine is getting hot!

Start with the project documentation describing the regex exclusion option, then run the proposed sloc command against an NPM project containing node_modules. Confirm the correct regex or command and update the documentation with an example that clearly excludes node_modules.
