+Usage:
+For comparing files created my cairo-perf:
+
+	$argv0 old.perf new.perf
+
+For comparing (cached) performance of revisions:
+
+	$argv0 [OPTIONS] <revision> [-- cairo-perf options]
+	$argv0 [OPTIONS] <rev1> <rev2> [-- cairo-perf-options]
+
+If given a single revision, compares its results to that of its
+(first-parent) predecessor. Otherwise compares the two given revisions.
+The revisions can be any revision accepted by git. For example:
+
+	$argv0 HEAD		# Show impact of latest commit
+	$argv0 1.2.0 1.2.4	# Compare performance of 1.2.0 to 1.2.4
+
+Options:
+
+-f, --force
+	Forces cairo-perf-diff to re-run performance tests
+	even if cached performance data is available.
+
+-h, --html
+	With this option performance changes are summarized
+	as HTML table.
+
+Additional options can be passed the child cairo-perf process
+by separating them with a double hyphen (--). For example, to
+examine what the impact of the latest change is on the stroke
+test you might use:
+
+	$argv0 HEAD -- stroke
+
+The performance results are cached in .perf next to the .git directory.
+
+Set CAIRO_AUTOGEN_OPTIONS to pass options to autogen for both
+builds.
