[sentinix-list] How do I update Snort & rulesets?

Hi again
Can anyone give some advice on how I can update my SNORT to the latest version and keep my rulesets up to date?  Snortcenter keeps the rules all bundled into the same file as the SNORT conf info, so it does not look like Oinkmaster or even manual file copying would work.  Surely it does not mean editing the conf file with the rules manually???

Thanks!
