52°North uses Subversion to manage source code. Instructions regarding Subversion use can be found at http://svnbook.red-bean.com/
All 52°North repositories have read access.The following is a link to the online source repository.
Download code via anonymous access
The source code can be checked out anonymously from SVN at the repository base URL:
Developer access for committing code
If you are interested in committing code to one of the 52°North repositories, you must receive write access from the respective community leader/code manager:
Once you have write access, you are ready to submit code. Committers must checkout the Subversion repository via HTTPS. Please use one of the URLs from above to get to the right community branch.
For those users stuck behind a corporate firewall which blocks http access to the Subversion repository, you can try to access it via the developer connection (see above).
The Subversion client can go through a proxy, if you configure it to do so. First, edit your "servers" configuration file to indicate which proxy to use. The files location depends on your operating system. On Linux or Unix it is located in the directory "~/.subversion". On Windows it is in "%APPDATA%\Subversion". (Try "echo %APPDATA%", note this is a hidden directory.)
There are comments in the file explaining what to do. If you don't have that file, get the latest Subversion client and run any command; this will cause the configuration directory and template files to be created.
Example : Edit the 'servers' file and add something like :
http-proxy-host = your.proxy.name
http-proxy-port = 3128
