+# This is a template for a script used for day-to-day size and 
+# performance monitoring of SQLite.  Typical usage:
+#
+#     sh run-speed-test.sh trunk  #  Baseline measurement of trunk
+#     sh run-speed-test.sh x1     # Measure some experimental change
+#     fossil test-diff --tk cout-trunk.txt cout-x1.txt   # View chanages
+#
+# There are multiple output files, all with a base name given by
+# the first argument:
+#
+#     summary-$BASE.txt           # Copy of standard output
+#     cout-$BASE.txt              # cachegrind output
+#     explain-$BASE.txt           # EXPLAIN listings (only with --explain)
+#
