/** An OptionEntry defines a single option. To have an effect, it must be added to an OptionGroup with
 * OptionGroup::add_entry().
 *
 * The long name of an option can be used to specify it in a commandline as --long_name.
 * Every option must have a long name. To resolve conflicts if multiple option groups contain the same long name, it is also
 * possible to specify the option as --groupname-long_name.
 *
 * If an option has a short name, it can be specified as -short_name in a commandline.
 *
 * The description for the option is shown in the --help  output.
 *
 * The arg_descripton is the placeholder to use for the extra argument parsed by the option in --help  output.

   *  @var Flags NONE

   * 
   *  @var Flags HIDDEN
   * The option doesn't appear in `--help` output.
   * 
   *  @var Flags IN_MAIN
   * The option appears in the main section of the
   * `--help` output, even if it is defined in a group.
   * 
   *  @var Flags REVERSE
   * For options of the G_OPTION_ARG_NONE kind, this
   * flag indicates that the sense of the option is reversed. i.e. <tt>false</tt> will
   * be stored into the argument rather than <tt>true</tt>.
   * 
   *  @var Flags 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). @newin{2,8}
   * 
   *  @var Flags 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. @newin{2,8}
   * 
   *  @var Flags OPTIONAL_ARG
   * For options of the G_OPTION_ARG_CALLBACK 
   * kind, this flag indicates that the argument supply is optional.
   * If no argument is given then data of OptionParseFunc will be
   * set to <tt>nullptr</tt>. @newin{2,8}
   * 
   *  @var Flags NOALIAS
   * This flag turns off the automatic conflict
   * resolution which prefixes long option names with `groupname-` if 
   * there is a conflict. This option should only be used in situations
   * where aliasing is necessary to model some legacy commandline interface.
   * It is not safe to use this option, unless all option groups are under
   * your direct control. @newin{2,8}
