[OTish] Version Control?

[Richard Clarke]

Does anyone in the list use any kind of version control (e.g. CVS) for the perl/template codebase of their website?
Now that my code base is growing I feel the increasing need to provide better version/backup control than my current hourly crontab tar.
I don't however feel that the organizational logic of a websites code base fits well into the CVS paradigm. Am I being to short sighted in this assumption?
Does anyone have any recommended method? I don't use version numbers at all? Does anyone?

Richard.
