The Spanners demo project is now available on GitHub: https://github.com/hotblac/spanners. Feel free to fork!
I wanted to migrate the Spanners demo from SVN to Git, partly so I could take advantage of GitHub to host it (yes, I know I could host a SVN project on GitHub but where’s the fun in that?). I also wanted to start using a Distributed Source Control Management (DSCM) system and Git is certainly the most popular of these. Even though I’m (currently) the sole contributor to the Spanners demo project, it’s useful to understand how a DSCM system differs from a ‘traditional’ centralized server based SCM such as SVN and CVS.
