Have you written features? If you haven't, you should be - because that is the right way to deploy stuff to your sites.

But if you have written them, I bet you have seen yourself trying various elements in the elements.xml file(s), guessing, and heck even reverse engineering parts of sharepoint that ship with sharepoint.

Here is a quick trick.

You can export the entire list schema as CAML using the following -

http://yoursiteurl/_vti_bin/owssvr.dll?Cmd=ExportList&List=%7YourListGUID%7D

This is quite awesome, because it straight off gives you all the Fields, Views, and Content Types involved.

From here, you can copy paste stuff into your feature.

Nice huh?
