Hi,

I'm trying to package elm-test.  It depends on Commander.js, which is 
packaged as js-commander in gnu/packages/javascript.scm. In order for 
elm-test to find Commander.js, I modified js-commander to use 
node-build-system.  Should I also move it to gnu/packages/node-xyz.scm 
and/or rename it to node-commander?

I've attached the current patch.

Matt
