• master: contains the mainline development code (usually stable)
• event-driver: [MERGED] contains the transition code to an event-driven paradigm. This will help us write maintainable code and develop autonomous code on top of a state machine. (unstable)
• gyro-autonomous: contains the transition code to an autonomous strategy where we use the gyro sensor.

• event-driver-a1: "Event Driver Alpha 1" - the first "working" revision of the event interface with only controller events. This is meant to be an initial demo and skeleton for 'pollEvent().' [unstable]
• event-driver-a2: "Event Driver Alpha 2" - just event-driver-a1 with bugfixes. The featureset is much more stable. No new features. [unstable]
• event-driver-a3: "Event Driver Alpha 3" - final engine and tankdrive code before merge into master [stable]
• legacy-final: "Final Legacy Tag" - the point right before a massive recoding started
