The type for exit code information.

exit_info ~docs ~doc min ~max describe the range of exit statuses from min to max (defaults to min). doc is the man page information for the statuses, defaults to "undocumented". docs is the title of the man page section in which the statuses will be listed, it defaults to Manpage.s_exit_status.

In doc the documentation markup language can be used with following variables:

• $(status), the value of min.
• $(status_max), the value of max.
• The variables mentioned in the Cmd.info

info_code i is the minimal code of i.

defaults are exit code information for ok, some_error cli_error and internal_error.
