 /**
  * @class KIO::AuthInfo authinfo.h <KIO/AuthInfo>
  *
  * This class is intended to make it easier to prompt for, cache
  * and retrieve authorization information.
  *
  * When using this class to cache, retrieve or prompt authentication
  * information, you only need to set the necessary attributes. For
  * example, to check whether a password is already cached, the only
  * required information is the URL of the resource and optionally
  * whether or not a path match should be performed.  Similarly, to
  * prompt for password you only need to optionally set the prompt,
  * username (if already supplied), comment and commentLabel fields.
  *
  * <em>SPECIAL NOTE:</em> If you extend this class to add additional
  * parameters do not forget to overload the stream insertion and
  * extraction operators ("<<" and ">>") so that the added data can
  * be correctly serialized.
  *
  * @short A two way messaging class for passing authentication information.
