The bryght repository seems to be down.
So here are the urls to the drpkg and relations svn repositories maintained at MEC by me. I will be syncing them to bryght regularly.
To checkout the relations code do:
svn co svn://mec0026.engi.cf.ac.uk/relations
To checkout the drpkg code do:
svn co svn://mec0026.engi.cf.ac.uk/drpkg
Update: It is back up, but I'll keep both in sync.
Update: repaired the typo
