  # inside gdb to use gdb commands if you need to debug.
  # If you want a LOT of debugging information (at the expense of
  # really slow code), try using -g3. That will even let you debug

  # This produces profiling output for gprof. If you want to use
  # the Solaris profiler, use -xprofile instead.

  # Optimization
