-    The main function <code>archetypes</code> implements a framework
-    for archetypal analysis supporting arbitary problem solving
-    mechanisms for the different conceputal parts of the algorithm. 
+    The <a href="http://www.merriam-webster.com/dictionary/archetype">Merriam-Webster
+    Online Dictionary</a> defines an archetyp as the original pattern
+    or model of which all things of the same type are representations
+    or copies. Then, the aim of the archetypal analysis is to find the
+    "pure types", the archetypes, within a set defined in a specific
+    context. The concept of archetypes is used in many different
+    areas, the set can be defined in terms of literature, philosophy,
+    psychology and also statistics. Here, the concrete problem is to
+    find a few, not necessaily observed, points (archetypes) in a set
+    of multivariate observations such that all the data can be well
+    represented as convex mixtures of the archetypes.
