    longDescription = ''
      TaskJuggler is a modern and powerful, Open Source project management
      tool. Its new approach to project planing and tracking is more
      flexible and superior to the commonly used Gantt chart editing
      tools. It has already been successfully used in many projects and
      scales easily to projects with hundreds of resources and thousands of
      tasks.
