Currently this is not an option right now due to time constraints and
my limited Python knowledge.

So, I change the custom hook based on example above.

- Copy the script `mattermost.py` to build master directory
- Change master.cfg to,

```
from mattermost import MattermostCommandHandler

c['www'] = {
        ...
	,	"change_hook_dialects":{
			"base": {
				"mattermost": MattermostCommandHandler
			}
		}
	}
```

- Restart the buildmaster service
- Test executing command from Mattermost

Output from buildmaster,

  2017-11-03 04:20:09+0000 [_GenericHTTPChannelProtocol,0,172.32.1.208] The dialect specified, 'mattermost', wasn't whitelisted in change_hook
  2017-11-03 04:20:09+0000 [_GenericHTTPChannelProtocol,0,172.32.1.208] Note: if dialect is 'base' then it's possible your URL is malformed and we didn't regex it properly

Does the "base" config above translated to "/custom_hook/mattermost"?

And then I try load custom hook with following config,

```
c['www'] = {
        ...
	,	"change_hook_dialects":{
			"base": {
				"mattermost": MattermostCommandHandler
			}
                ,       "mattermost": True
		}
	}
```

The buildmaster output,

  2017-11-03 04:25:17+0000 [_GenericHTTPChannelProtocol,0,172.32.1.208] The dialect specified, 'mattermost', is not registered as a buildbot.webhook plugin

Thanks in advance for your help.
