Declarative Command-line Parsing for OCaml

Cmdlang is a library for creating command-line parsers in OCaml. Implemented as an OCaml EDSL, its declarative specification language lives at the intersection of other well-established similar libraries.

Cmdlang doesn't include an execution engine. Instead, Cmdlang parsers are automatically translated to cmdliner, core.command, or climate commands for execution.

Our goal is to provide an approachable, flexible, and user-friendly interface while allowing users to choose the backend runtime that best suits their needs.
