+#     sh speed-check.sh trunk  #  Baseline measurement of trunk
+#     sh speed-check.sh x1     # Measure some experimental change
+#     fossil xdiff --tk jout-trunk.txt jout-x1.txt   # View chanages
+#
+# There are multiple output files, all with a base name given by
+# the first argument:
+#
+#     summary-$BASE.txt           # Copy of standard output
+#     jout-$BASE.txt              # cachegrind output
