xNOTIFY  File|Directory  ON|OFF

  Will set up notification on a file or directory and will "happen"
  every time the given file/dir changes in some way (i.e. if it
  is written to or deleted or whatever).

  > xNOTIFY Ram:MyFile ON

  If the file/dir doesn't exist, you will get notified if and when
  it is created.

  As with other events, you can give it a  GADID  and 
   SETGAD  it ON|OFF at any time.

  You can also  UPDATE  it, giving a new file/dir name.
