How do i generate documentation for my Class Library?

Question

hi,
I have written some class libraries with XML inline documentations. In ealier version of VS such as 2002 / 2003 had CHM documentation generation tool. But afterwards i couldnt find any tools to generate documentation at the moment i use VS 2008 TS and Visual Web developer 2005 Express. I've checked the DVDs for documentation generation tools but i couldnt find any.... so how do i generation documentations for my libraries?
Are there any free tools if VS doesnt provide one?
TY
