#
# This example shows an example of reasoning about a role's parameters.  There
# are 4 principals StateU, Bob, Maryann, and Joe.  StateU wants to establish a
# set of founding alumni based on the year of graduation.  On graduation each
# alum has previously been issued a credential parameterized with their major
# and graduation year.  StateU sets up a policy that says that a principal is a
# founding alum if they graduated in 1960, 1961, or 1963 no matter what major
# the principal had.  One assumes there was some kind of NCAA suspension in
# 1962.  This policy is expressed in Credential 1.
#
# Credentials 2, 3, and 4 each assign a diploma credential to Bob (a 1961
# mathematics degree), Joe (a 1955 zoology degree) and Maryann (a 1962
# psychology degree).
#
# The query.py file asks if each of these principals are favored
# alums, and only Bob is.
