Description:

Content:

Enum values:

• HIDDEN - The option doesn't appear in `--help` output.
• IN_MAIN - The option appears in the main section of the `--help` output, even if it is defined in a group.
• REVERSE - For options of the g_option_arg_none kind, this flag indicates that the sense of the option is reversed.
• NO_ARG - For options of the g_option_arg_callback kind, this flag indicates that the callback does not take any argument (like a g_option_arg_none option).
• FILENAME - For options of the g_option_arg_callback kind, this flag indicates that the argument should be passed to the callback in the GLib filename encoding rather than UTF-8.
• OPTIONAL_ARG - For options of the g_option_arg_callback kind, this flag indicates that the argument supply is optional.
• NOALIAS - This flag turns off the automatic conflict resolution which prefixes long option names with `groupname-` if there is a conflict.
