/* This is the interface to the embeddable prompt service; the service
   that implements nsIPrompt. Its interface is designed to be just
   nsIPrompt, each method modified to take a parent window parameter.
   See nsIPrompt for all documentation and ancillary documentation.

   Accesskeys can be attached to buttons and checkboxes by inserting
   an & before the accesskey character. For a real &, use && instead.

   One note: in all cases, the parent window parameter can be null.
   However, these windows are all intended to have parents. So when
   no parent is specified, the implementation should try hard to find
   a suitable foster parent. */
