> Initial release adds the ability to START and STOP backends (or any

> with "startsecs" parameter, then supervisord (and ngx_supervisord) will wait

> This simple feature, combined with load-aware load balancers (like Grzegorz
> Nosek's nginx-upstream-fair) can offer very powerful features (starting
> first backend when the first request arrives, starting/stopping backends on
> demand, depending on the load, etc, etc). Patch for nginx-upstream-fair is
> included in the release and it shows how easy all of this can be achieved.
> Current version allows only one module to "register" its monitors with
> ngx_supervisord, but as soon as there will be need for more (read: other
> modules will start using ngx_supervisord), this will be changed without any
> changes in the API.
> If something is unclear, just ask.
> This module was fully funded by megiteam.pl
