| # PulseAudio memory usage plotting script | |
| # | |
| # Before invocation, generate necessary data by running the | |
| # 'benchmark_memory_usage.sh' bash script. Afterwards, you can plot | |
| # such data by running: | |
| # | |
| # gnuplot plot_memory_usage.gp | |
| # | |
| # Note! To avoid scaling issues, memory is plotted in a "double y axis" | |
| # form, with VM usage on the left, and dirty RSS memory usage on the | |
| # right. The scales are different. | |

| # Print our user messages to the stdout | |
