Relevant bits of opam:

https://github.com/ocaml/opam/blob/c4961baf23e681c74b381a5f9c2cfd7362740e68/src/client/opamCommands.ml#L4386-L4390

Cmd.info docs: https://erratique.ch/software/cmdliner/doc/Cmdliner/Cmd/index.html#val-info

Still not entirely clear how they automatically get the version number without hardcoding it in.
