Profiling with Valgrind

Rather than using gprof to profile programming code Valgrind appears to be a more fully featured alternative, it's available here:

http://valgrind.org/

You couple the output from Valgrind with VGprof to produce gprof formatted data, VGprof is available here:

Then take the gprof formatted output and create easy to read HTML reports using PyProfGen, available here:
