Presence is a Python program that performs runtime environment information discovery.

Presence looks for configuration in /etc/datawire/presence.yml

Example:

---
lookup: net(eth0)
watson_plugins:
 - /etc/datawire/watson.yml

1. ec2
2. docker
3. custom (see: Custom Environment Plugin)

Environments can be unique and it is not possible for Presence to support every known configuration.

A custom presence plugin allows developers to implement custom network discovery logic.
