Get summary of generated rules after return from supgem():

rules(sumfile ="rules.sum")

Optional argument:

   sumfile = "name" of file containing rule summary printout.
      Must be the same as specified (or not) in call to supgem().

Example:

   summary <- rules()

Remarks:

   This procedure returns the summary as a vector of type character, one
   element for each output line. To see the summary in a more readable
   format, use rules() in conjunction with the function see().
