To use the pretty graphs you have to first build/run the ltmtest from the root directory of the package. Todo this type make timing ; ltmtest in the root. It will run for a while [about ten minutes on most PCs] and produce a series of .log files in logs/. After doing that run "gnuplot graphs.dem" to make the PNGs. If you managed todo that all so far just open index.html to view them all :-) Have fun Tom
