Http://zh.wikipedia.org/wiki/Sourceforge SourceForge is a collaborative software development management system. SourceForge is a proprietary software sold by va software. It integrates many open-source applications (such as PostgreSQL, SVN, and CVS) and provides a full set of lifecycle services for software development.
Sourceforge.net, also known as sf.net, is a centralized place for developers of open-source software to conduct development and management. It is also the world's largest open-source software development platform and warehouse. Sourceforge.net is a host provided by va software and runs SourceForge software. A large number of open-source projects have been settled here (June 2005 projects and 125,090 registered users have been reached in 1,352,225), including mediawiki used by Wikipedia, but it also contains many projects that stop development and one-person development.
