CI MVC and SVN

[eluser]searain[/eluser]
When we use SVN on CI project.

Which folder is used to be put in SVN control?

For the project I am doing now, I think I could put "application" folder in SVN. The other folders at the same or upper level of "application" don't have to be put in SVN.

What do you do when use SVN on CI?

Thanks!
