 OVERVIEW: In this library, new methods for factorization on polynomials
-  are implemented for two algebras over a field K. Recall, that
-  the first Weyl algebra over K is generated by x,d obeying the relation d*x=x*d+1.@*
-  The first shift algebra over K is generated by x,s obeying the relation s*x=x*s+s.
+  are implemented for two algebras, both generated by two generators (Weyl and 
+  shift algebras) over a field K. Recall, that   the first Weyl algebra over K 
+  is generated by x,d obeying the relation d*x=x*d+1.
+@* The first shift algebra over K is generated by x,s obeying the relation s*x=x*s+s.
+@* More detailled description of the algorithms can be found at @url{http://www.math.rwth-aachen.de/\~Albert.Heinle}.
+
+Guide: We are interested in computing a tree of factorizations, that is at the moment
+a list of all found factorizations is returned. It may contain factorizations, which 
+are further reducible.
