title: Add auto-incremented build number into Meteor app?
body: <p>How do I add an auto-incremented build number into an about screen?</p>
  
  <p>By that I mean I want part of my version number auto-generated e.g. v2.2.0018 where "v2.2" is manually decided and "0018" is based on the number of check-ins in github, or other metric. I'm not fussed if it's specifically check-ins or whatever, just important that I can uniquely identify that build for support and issue reproduction purposes. And strongly prefer to have a simple incremental integer rather than a hash.</p>
  
  <p>I'm using Meteor + Webstorm + Github + Heroku. I'm building web + ios + android apps off the same codebase.</p>
  
  <p>Thanks.</p>
