// The package managers the benchmark installs with, and the command each is
// measured running. Nothing here says what a column is called or what colour
// it is drawn in: this repository publishes numbers, and how they are
// presented belongs to whoever presents them.
//
// Nor does anything here say which of them a reader is shown. Every manager
// listed is measured and reported in `benchmarks.json`; pnpm.io draws npm and
// the pnpm columns from it, and the rest are measured for our own comparisons.
