Creating web user control and using it in two different websites

Question

Hi,
I am creating a web user control for my website. I have created it and also using it.
Now, what I want to do is using this same web user control in another website. for this i have to manualy copy the files and have to make necessary changes to these files.
So my question is: Is there any way to create a DLL with this web user control as in case of winforms so that we can use web user control in as many as application
thanks
