+To make a basic load plot:
+
+* Generate the LOG (may set log4j.logger.swift=INFO for this one)
+  (assuming the log is titled swift-run.log)
+* Make the execute transitions file:
+  make LOG=swift-run.log execute.transitions
+  These transitions are relative to the Unix epoch
+* Make the start time file (this contains the earliest timestamp)
+  make LOG=swift-run.log start-time.tmp
+* Normalize the transition times
+  ./normalise-event-start-time < execute.transitions > execute.norm
+* Build up a load data file:
+  ./accumulate-load.pl < execute.norm > load.data
+* Plot with the JFreeChart-based plotter:
+  lines.zsh load.cfg load.eps load.data
