This is Tigger.

Roadmap: Pivotal tracker integration coming soon!

Installation: Navigate to the directory you downloaded tigger to. Type "make" You're ready to roar.

Usage: (In a project dir that uses Git)
tigger // this will print out usage

tigger init //this initializes relevant tigger files

tigger new "Complete this task"

tigger tasks //will print out all the current tasks

git commit -am "Complete this task" //Tigger will automagically know that you have completed a task

Monitor tasks with color:

watch --color -n 60 -- tigger -c tasks

This will refresh every 60 seconds in color your list of tasks.
