title: Heroku: Compiled slug size is too large (max is 300MB)
body: <p>It's been a while since I last pushed my Rails 3.2.13 app to Heroku.  Now the push is failing because of this error:  "Compiled slug size: 1423.7MB is too large (max is 300MB)".</p>
  
  <p>The only solutions Ive found request me to reduce my slug size by reducing gems and such. There's not much I can do to reduce gems.  Why is Heroku limiting this push?  Is there a way around this?</p>
  
  <p>UPDATE: I checked the file size for each file in my app and found that my 'public' folder had over 1.4GBs of data which consisted (in the 'uploads' subfolder) of carrierwave file uploads stored to the app before started using plugged Amazon S3.  So I created a '.slugignore' file and added '/public/uploads'.  </p>
