# Display a list of authors and their occurrence in the bibfiles
#
# each output line is of the form:
#
# Surname,I N
#
# where I is their initial and N is the number of occurrences. This can be
# fed throug sort -n -r +1 to get a list of authors in descending order
# of occurrence. Figure out who is your favourite co-author!
