Read-only Access
Read-only repository access is provided through git://roundup.git.sourceforge.net/gitroot/roundup/roundup
git clone git://roundup.git.sourceforge.net/gitroot/roundup/roundup roundup
Read-write Access
The read/write access uses your SourceForge.net ssh password or ssh key to authorize your access. (See SF’s site documentation on git authorisation)
git clone ssh://<username>@roundup.git.sourceforge.net/gitroot/roundup/roundup roundup
Of course a roundup developer must have granted you write access first - ask for it on the roundup-devel list.
