+     "This is a package supporting cluster analysis for cognitive diagnosis
+based on the Asymptotic Classification Theory (Chiu, Douglas & Li, 2009;
+@url{doi:10.1007/s11336-009-9125-0}).  Given the sample statistic of
+sum-scores, cluster analysis techniques can be used to classify examinees into
+latent classes based on their attribute patterns.  In addition to the
+algorithms used to classify data, three labeling approaches are proposed to
+label clusters so that examinees' attribute profiles can be obtained.")
