Important Notes:

  • ALL of the admin CVS/SVN stuff has been centralized to trac.cs.earlham.edu/admin. You'll need to create a username/password for yourself by running (from quark):
htpasswd /usr/local/trac/adminontrac.htpasswd <username>
  • To check out the repository, run (from quark):
svn checkout file:///clients/users/svn/admin
