You've reached the front page of my and Briand's CCI Tutorial from the WWW3 Conference in Darmstadt, April 1995. If this is where you really wanted to be, please feel free to continue.
However...if you want the latest tutorial on client interfaces, you should really be looking for our tutorial from WWW4 in Boston, December 1995. The URL for that tutorial is http://it.ncsa.uiuc.edu/~mag/work/CCI/BostonTutorial/.
