+# [default: anything on the cmd line this script doesn't recognise ]
+# the first opt not starting w/ "-" is taken to be an input
+# file and (if it exists) is grepped for "what's going on here"
+# comments (^--!!!).
+# * a file to feed to stdin ( -i<file> ) [default: /dev/null ]
+# * a "time" command to use (-t <cmd>).
+#
+# * alternatively, a "-script <script>" argument says: run the
+# named Bourne-shell script to do the test. It's passed the
+# pgm-to-run as the one-and-only arg.
+#
+# Run the program with those options and that input, and check:
+# if we get...
+#
+# * an expected exit status ( -x <val> ) [ default 0 ]
+# * expected output on stdout ( -o1 <file> ) [ default /dev/null ]
+# ( we'll accept one of several...)
+# * expected output on stderr ( -o2 <file> ) [ default /dev/null ]
+# ( we'll accept one of several...)

+# (if the expected-output files' names end in .Z, then
+# they are uncompressed before doing the comparison)
