The Redmine project management system includes Gantt
charts, a calendar, a roadmap, and other helpful features you can
use to keep track of what’s going on with your software development
projects. (You can use Redmine for any other kind of project you
care to manage, but it’s clearly aimed at software development.) It
includes bug-tracking and support ticketing, allowing you to track
feature, bug, and support requests along with project management
for your next software release. Redmine also provides news and
document management, a per-project wiki, and per-project forums.
Does all that sound intriguing?
