I’m not sure it’s worth adding another dependency just to output debug information. Couldn’t we just use process.platform?

[aladdin-add]

the package can output more readable info, e.g.

osName('win32', '6.3.9600');
//=> 'Windows 8.1'

I think either is fine. will remove the dependency if you prefer that way. :)

[nzakas]

As I said, I just don’t think this is important enough to add another dependency. Win32 or Win64 is plenty of info for our purposes.

[aladdin-add]

just rebased the latest master.

LGTM

I think we can already mark this as accepted, since it matches our new bug report template.

Can we use sinon here to prevent this change from leaking to other tests?

LGTM, thanks!
