"""This program displays the group data (as calculated by ``groups.about``) for
a group generated from a list of permutations specified on the command line.
Each permutation must be written as a sequence of cycles separated by ``/``,
where each cycle is a sequence of positive integers separated by ``,``. For
example, the command:
symdata.py 1,2/3,4 3,4,5
displays the data for the group generated by ``(1 2)(3 4)`` and ``(3 4
5)``."""
