CEE/Lumberjack log formatter for Ruby/Rails

Both rsyslog and syslog-ng support CEE in their latest versions. This allows you to format your Ruby/Rails logs in that format.

The envisioned use is to output your logs in CEE format to STDOUT and have your running environment pipe them to a logger command.

What is CEE/Lumberjack?

CEE is short for Common Event Expression. It is a structured format for logs. Lumberjack is a project to implement and standardize around CEE.
