Removes old versions of compiled assets.

2 previous versions as well as any digest created

## Options
* `-o, --output` - indicates the path to your compiled
assets directory. Defaults to `priv/static`
* `--age` - specifies a maximum age (in seconds) for assets.
Files older than age that are not in the last `--keep` versions
will be removed. Defaults to 3600 (1 hour)
* `--keep` - specifies how many previous versions of assets to keep.
Defaults to 2 previous versions
* `--all` - specifies that all compiled assets (including the manifest)
will be removed. Note this overrides the age and keep switches.
