  Neros publishes no client library on npm, PyPI, Maven Central, NuGet, pkg.go.dev,
  RubyGems, Packagist or crates.io (all probed, no first-party package found). Its
  first-party libraries are distributed as source from the Neros-Technologies GitHub
  organization and consumed either as drop-in C source, a static library built by a
  Makefile, or a Bazel module.
