Sprockets::Manifest#clean

Cleanup old assets in the compile directory. By default it will
keep the latest version, 2 backups and any created within the past hour.

Examples

  To force only 1 backup to be kept, set count=1 and age=0.

  To only keep files created within the last 10 minutes, set count=0 and
  age=600.
