`--benchmark_min_time` command line option undocumented #1878

The documentation mentions it once but I couldn't find comprehensive documentation for it. As far as I can tell, this option can be used for two things

  1. Set the min duration of a repetition with --benchmark_min_time=<value> or --benchmark_min_time=<value>s.
  2. Set the desired number of iterations per repetition with --benchmark_min_time=<value>x (for benchmarks not registered with a fixed number of iterations).

This seems like it relates to https://github.com/google/benchmark/issues/746

Are both of these bits of behaviour officially supported? If yes, it would be helpful to document them.

if they're in the code, they're supported. if we're missing some documentation, i'm happy to take PRs improving the docs.
