program Clean;

 { 
  The program registers as a explorer extension. 
  Use rightclick on a Delphiproject directory and choose Clean Delphi files. 
  Place the executable somewhere in program files and run once. 

  Dieses Program registriert sich beim Ausfuhren als 
  Explorer-Erweiterung. 
  Mit einem Rechtsklick auf ein Delphi Verzeichnis und 
  einem Klick auf "Clean Delphi files" werden die Verzeichnisse "aufgeraumt".
