+# 2)  Sorting Test
+#
+#     Sort an input file that consists of lines like this
+#
+#         var1=23 other=14 ditto=23 fred=2
+#
+#     such that each output line is sorted WRT to the number.  Order
+#     of output lines does not change.  Resolve collisions using the
+#     variable name.   e.g.
+#
+#         fred=2 other=14 ditto=23 var1=23
+#
+#     Lines may be up to several kilobytes in length and contain
+#     zillions of variables.
+
+# This implementation:
+# - Reads stdin, writes stdout
+# - Uses any amount of whitespace to separate fields
+# - Allows signed numbers
+# - Treats illegally formatted fields as field=0
+# - Outputs the sorted fields with exactly one space between them
+# - Handles blank input lines correctly
