This program reads memory usage information produces aggregated totals
according to the `--report-by` option:
* `--report-by section` (the default) aggregates memory usage by section.
* `--report-by region` aggregates memory usage by region. A region is a
  configuration-defined group of sections.

Use `--collect-method=help` to see available collection methods.
Use `--output-format=help` to see available output formats.
