The "ocaml" command is used to start the OCaml interactive toplevel, also known as the OCaml interpreter. OCaml is a language in the ML family of programming languages, primarily used for functional programming.

When you run the "ocaml" command in your terminal or command prompt, it opens the OCaml toplevel where you can directly interact with the OCaml language and evaluate expressions. It provides a read-eval-print loop (REPL) environment, meaning it reads in OCaml expressions, evaluates them, and then prints the result.

This is useful for experimenting with OCaml code, testing small code snippets, and quickly evaluating expressions. It also provides a way to learn OCaml interactively, allowing you to explore the language's features and functionality.
