+# Usage:
+#
+#       From the shell:
+#
+#               ./square
+#               cat file | ./square
+#               echo "123" | ./square
+#
+#       Within calc:
+#
+#               > read square
+#
+#  With input from a terminal, there is no prompt but each non-empty
+#  line of input is evaluated as a calc expression and if it can be
+#  calculated, the square of the value of that expression is displayed.
+#  Execution stops when an empty line is input.
+#
+#  From the shell:
+#
+#       ./square
+#
+#  The following shows lines of input followed by output:
+#
+#       1234
+#               1522756
+#       ln(2)
+#               ~.48045301391820142467
