+Timings
+
+=head1 WHAT IT IS
+
+Extract move effect timings from a verbose trace log of the
+presentation engine. Generated is a gnuplot data file, which can be
+displayed issuing a 'gnuplot <filename>' or at a gnuplot prompt, via
+'load <filename>'.
+
+To generate such a verbose log file, rebuild module canvas and module
+slideshow with VERBOSE=t defined in the environment, and debug=t at
+the build tool command line. Then run the presentation, and redirect
+stdout to your log file.
+
+Call me like this: timings.pl < trace-file > gnuplot-target
+
+The whole point in doing this is to detect jerks in shape movements,
+which manifest themselves clearly in the graphed gnuplot output. Note
+that there's some heuristic to recognize when one effect ends and
+another has started: If the time difference between two subsequent
+page flipping times is more than one second, a new effect is assumed
+and a new gnuplot data record is generated.
