// This program converts an input file of written assignment scores from a
// boolean (0/1) form to a numerical form.  A 0 means someone did not do the
// written assignment, a 1 means they did.  Students get 3 points for each
// written assignment they complete with a maximum of 20 points.  The input
// file consists of input lines each of which have one student's written
// assignment in the 0/1 form.  The output file lists the corresponding points.
// The output is also echoed to System.out.
