check if a node tarball exists on the official website
Check to see if a .tar.gz of the node source you want exists on the official website.
Supports looking for versions 0.5.1 and up.
npm install checknode
var checknode = require'checknode'checknode'0.8.4'if !errres === 200 && console.log'version exists'res === 404 && console.log'version does not exist'
checknode uses isaacs' node-semver module to clean version input, so you can get a little crazy with version formatting if you really want.
=v.8.10 will both work because isaacs' module is really good like that.
