Better to follow the POSIX guidelines for command line arguments using some kind of getopt implementation.

It does not matter, i'll be glad to any implementation.

https://github.com/visionmedia/commander.js - good module.

I do not mind of the implementing this https://github.com/visionmedia/commander.js or https://github.com/davepacheco/node-getopt or something similar (but something slight and with a minimum count of dependencies). You are free to PR. Also @kobezzza you are free to add something like 'beforeCompiling' and 'afterCompiling' callbacks.
