DESCRIPTION

EARLY VERSION, ONLY A FEW FUNCTIONS HAVE BEEN BENCHMARKED.

Packaging a benchmark script as a Bencher scenario makes it convenient to include/exclude/add participants/datasets (either via CLI or Perl code), send the result to a central repository, among others . See Bencher and bencher (CLI) for more details.
