We've had a processing job crunching results for a couple months now that checks out a revision of our code, compiles it, and tests our geometry conversion.  Repeat that a hundred times and we have data spanning over a year of development that we'd like to see graphed.  The log files look like this:

Output was saved to conversion-16438-run.log from /home/sean/brlcad/NMG/r53000
Conversion testing complete.

Your task is to put that data into a spreadsheet or data file and create some graphs.  We're specifically interested in these graphs for all revisions:

• NMG failures
• BoT failures
• Success rate
• Conversion time (elapsed)

 The log files can be obtained from here:

• http://brlcad.org/tmp/NMG_conversion_logs.tar.gz

Submit the graphs and your datafile (or spreadsheet) along with any other details you'd like to provide (e.g., gnuplot commands you ran)
