# the task juggler is a very powerful project management tool that lets the user specify a task juggler project in a simple text format by listing all tasks and their dependencies. This text file is processed by TaskJuggler which produces various reports in html and xml format. The juggler does not only honor the task interdependencies, but also takes resource constraints into account. The user can create task lists, resource usage tables, status reports, project calendars, and project accounting statements by using the program's filtering and reporting algorithms. The program includes tools producing GANTT and Pert charts
