On page http://www.kde.org/applications/development/kdevelop/ I followed the link "KDevelop Handbook" to http://docs.kde.org/development/en/extragear-kdevelop/kdevelop/index.html, which claimed "The file /development/en/extragear-kdevelop/kdevelop/index.html could not be found." and told me to tell you, so I am. Thanks for your time.
