+
+These run "forever" on my machine and I don't feel like debugging

+  <longdescription lang="en">
+    This package provides various algorithms for computations with
+    polycyclic groups defined by polycyclic presentations. The features
+    of this package include,
+
+      * creating a polycyclic group from a polycyclic presentation
+        arithmetic in a polycyclic group
+
+      * computation with subgroups and factor groups of a polycyclic
+        group
+
+      * computation of standard subgroup series such as the derived
+        series, the lower central series
+
+      * computation of the first and second cohomology
+
+      * computation of group extensions
+
+      * computation of normalizers and centralizers
+
+      * solutions to the conjugacy problems for elements and subgroups
+
+      * computation of torsion and various finite subgroups
+
+      * computation of various subgroups of finite index
+
+      * computation of the Schur multiplicator, the non-abelian exterior
+        square and the non-abelian tenor square
