What is "fusionforge"

FusionForge is a free software application descendant of the forge (web-based project-management and collaboration software) originally created for running the SourceForge.net platform. FusionForge is licensed under the GNU General Public License, and is a fork/renaming of the code which was previously named GForge.

FusionForge provides project hosting, version control ( GNU arch, Bazaar, CVS, Darcs, Git, Mercurial and Subversion), bug-tracking, and messaging features which can be deployed to run a self-hosted forge.
