pkg/

A simple [supervisord](http://supervisord.org/) event listener to relay

process output to supervisor's stdout.

This is useful in situations where the output will be collected and set to

external logging framework, such as Heroku.

Just install via pip or add to your requirements.txt:

pip install supervisor-stdout

An example supervisord.conf:

[supervisord]

nodaemon = true

[program:web]

command = ...

stdout_events_enabled = true

stderr_events_enabled = true

[eventlistener:stdout]

command = supervisor_stdout

buffer_size = 100

events = PROCESS_LOG

result_handler = supervisor_stdout:event_handler
