title: Rails assets:precompile only one asset?
body: <p>Currently we have a Rails application but I have one question regarding the assets precompilation.</p>
  
  <p>Each time that I edit one file (stylesheet or javascript file), we have to run:<br>
  <code>bundle exec rake assets:precompile</code><br>
  ...and then upload everything again, even those files that didn't changed at all.</p>
  
  <p>Is there a way to compile only the edited files and the manifest.yml file?</p>
  
  <p>Thanks in advance.</p>
