Long time `minimist` user here. Leanest and simplest of the pack at just 200 LOC with _no_ dependencies by the legendary substack.

Unfortunately the documentation is scarce, it has a growing number of unresolved issues → https://github.com/substack/minimist/issues/50.

Parsec is only 50 LOC and the API is simpler, and still no dependencies!
