Program exits.
Support for B0_std.Os.Exit exits which are more evolved than those provided by cmdliner.
val ok : B0_std.Os.Exit.tok is the zero exit code.
val no_such_name : B0_std.Os.Exit.tno_such_name (122) indicates a named entity was not found.
val some_error : B0_std.Os.Exit.tsome_error (123) indicates an indiscriminate error reported on stdout.
val infos : Cmdliner.Cmd.Exit.info listinfos has the infos of Cmdliner.Term.default_exits, no_such_name, some_error and those above.
val of_eval_result :
?term_error:B0_std.Os.Exit.t ->
(B0_std.Os.Exit.t Cmdliner.Cmd.eval_ok, Cmdliner.Cmd.eval_error) result ->
B0_std.Os.Exit.tof_eval_result ~term_error r is:

This uses B0_std.Os.Exit.exit and in case of Error _ logs it and exits with exec_error which if given an exit code is then guaranteed to exit.
