def clean(keep_up_to: 2, age_in_seconds: 3600)

To only keep files created within the last 10 minutes: clean(0, 600)
To force only 1 backup to be kept: clean(1, 0)
Examples:

NOTE: By default keeps the last version, or 2 if created in the past hour.

age_in_seconds - Amount of time to look back in order to preserve them.
keep_up_to - Max amount of backups to preserve.

Public: Cleanup old assets in the output directory.
