+GrpConst is a GAP 4 package for constructing all groups of a given
+finite order (up to isomorphism).
+
+FrattiniExtensionMethod constructs all soluble groups of a given
+order.
+
+CyclicSplitExtensionMethod constructs all (necessarily soluble) groups
+whose given orders are of the form pn .q for different primes p and q
+and which have at least one normal Sylow subgroup.
+
+UpwardsExtensions takes as its input a permutation group G and
+positive integer s and returns a list of permutation groups, one for
+each extension of G by a soluble group of order a divisor of s.
+
+The programs in this package have been used to construct a large part
+of the Small Groups library.
