Using the miracle of cvs2svn, I have migrated the Arabica source from the Sourceforge CVS server to my Subversion server chugging away under my desk. I've only used Subversion seriously for a little while, but I have to say I rather like it. The CVS repository on SourceForge will remain available, but new development will now be committed to Subversion.
Anonymous access to the repository is available from
svn co svn://jezuk.dnsalias.net:/jezuk/arabica/trunk/
and the repository can be browsed at http://jezuk.dnsalias.net:/viewvc/.
