[Sussex] Reinventing the wheel

[John Crowhurst]

Hello,

I wonder if you could help by pointing me in the right direction.

I have a customer that wants to implement version control on his website 
so that when users upload files and folders they are copied elsewhere 
into another folder and compared to see if they have changed, and the 
changed files get tagged with a number for version control.

I'm sure there is a much better way to do this, such as checking in the 
files to CVS or similar.

Can anyone advise?

Best,

John
