Planner is the GNOME project management tool.
Its goal is to be an easy-to-use no-nonsense cross-platform project management application.
Planner is a GTK+ application written in C and licensed under the GPLv2 or any later version. It can store its data in either xml files or in a postgresql database. Projects can also be printed to PDF or exported to HTML for easy viewing from any web browser.
Planner was originally created by Richard Hult and Mikael Hallendal at Imendio. Thanks, guys, for your excellent work and continuing guidance as we work to improve on what you started.
