Build

• Static analysis via HHVM• Actually was implemented, but hphpa changed a lot (now it’s

https://github.com/sebastianbergmann/hhvm-wrapper)

Deployment

• Cronjob / CLI script handling• Web server (Apache, nginx) config manipulations• Ext- and lib- dependency verification via Composer• Custom script execution during deployment

What is not implemented yet
