Sysadmin

Important Notes:

• ALL of the admin (not the cluster, just 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

• Chatting on IRC
