Source Control

Hi,

What is the source control mechanism that can be used for sourcing Templates and Content Types etc…How can it be achieved?
What source control software can be used?

Please can someone throw light on this topic or guide me to some resources?

Thanks
Pallavi

Source control is a non-starter. How far you use CVS (or anything like it) for your own private reference purposes depends how much effort you are prepared to put in. See this thread.
