cvs usage question

[James Turner]

I just started using cvs to manage a new web project had a usage question 
I was wondering if anyone could help me with.  Once I run "cvs commit" in 
my local repos I would like the server to automatically run a 
"cvs update" on a checkout which is located on the same server as the cvs 
repos.  I was wondering if this was possible and how you might go out 
doing it.  Thanks.
