Finally after 3 days, wget has now completely retrieved http://www.valadoc.org
Inside this 7zip archive is localized-link of valadoc and vala-draft, I also supplying HtmlHelpProject for compiling into chm format (requires HtmlHelpWorkshop). All you need is load the project file and click compile, valadoc.chm will be created after a while. Due to filesize (around 50MB) I was unable to upload it for now.
valadoc-051510 (valadoc.org as retrieved at May 15 2010, 453MB uncompressed; 52MB as CHM)
