Jubjub is a decision tree based framework for automating *NIX administrative processes and reacting to events. Working well with a network monitor such as Nagios, you can expose, document, and add notifications to scripts in one step.
Gluon is a simple decision-tree daemon that executes external programs (scripts) to determine the path-flow within the decision-tree. It essentially operates as a basic IF-THEN-ELSE expert system that can be used to monitor and take action.
