Wraps the previous stable version of npm as an executable npm-prev.
Allows you to use previous stable npm alongside whatever other version of npm you currently have installed.
npm install -g npm-prev
Remember to run this semi-regularly to get the latest version of npm v3.
Make sure you understand what's changing in npm v3 by reading the excellent Release Notes.
The npm-prev executable behaves exactly like npm:
> npm-prev -v
2.14.5
> npm-prev install
> npm-prev search
# etc
