Exploratory tests

The vcs-command package introduces an executable, ocaml-vcs, designed to bring the core functionalities of ocaml-vcs directly to your command line.

It's a practical tool for conducting exploratory testing within your repositories, and reproducing bugs or issues externally, for a smoother debugging process. As a live code sample, it also demonstrates the use of the library.

Whether you're testing new features, diagnosing problems, or seeking to understand the library's application, ocaml-vcs can be a useful resource.

Below is a quick overview of the commands available in ocaml-vcs:
