Trajectory http://apptrajectory.com/ is a project estimation and management tool for project managers, product managers, developers, and designers. It is heavily inspired by, but improves upon, Basecamp and Pivotal Tracker. Like Basecamp, it has a place to organize ideas and exchange free-form feedback; like Pivotal Tracker it has the concept of stories with points instead of time estimations, and it calculates time estimations based on past performance. It also weds the two concepts, connecting stories with ideas. This is a collection of tools and libraries for interacting with Trajectory. It provides the lsstory tool, a command-line app that can list stories, filtering by source idea, milestone, point, assignment, whether design or development is needed; it can filter on the state (unstarted, started, finished, done); it can filter on the iteration. It can also be used simply to tell you the next unstarted, unassigned development story to work on. To build more with this package, look into the Trajectory.API module.
