This is outdated. In January 2013 the BOINC project switched to the git-scm version control system. See SourceCodeGit for more information.

BOINC uses Subversion (aka "SVN") for source code version control. The main SVN repository is at https://boinc.berkeley.edu/svn/, which you can explore with a web browser. The latest development version of the code is in the trunk, while the most stable server code is in branches/server_stable.

You need an SVN client to check code out in bulk from the repository. On Linux the command line command is simply svn. On Windows TortoiseSVN provides a useful graphical interface. See http://subversion.tigris.org/ for detailed information about Subversion and information about other SVN clients.

• Detailed instructions on how to obtain the BOINC source code via SVN are on the SourceCode page

• More information about SVN can be found in the the Subversion Book.
