## Blackfire support
## ------------------
## First register the blackfire agent with:
#bin/root blackfire-agent --register --server-id={YOUR_SERVER_ID} --server-token={YOUR_SERVER_TOKEN}
## Then uncomment the below line (and leave uncommented) to start the agent automatically with bin/start:
#bin/root /etc/init.d/blackfire-agent start

bin/cache-clean --watch
