Using .npmrc for private npm packages

[thatgibbyguy]

My company utilizes a private module for its style guide. I can currently pull in as a git submodule but using it as an NPM module would be much preferred.

However, I do not see in your documentation a way to utilize .npmrc or where to specify what private registry to use for private NPM modules. Is this possible with meteorhacks/npm? Thanks for everything!
