               be added into the IDE by adding AddInIDEU.pas into a
               package that is installed into Delphi, or into an 
               application by adding the AddInU.pas unit into a uses 
               clause and calling the StartObjectBrowser procedure

RegTweak.dpr - This app can be used to set undocumented registry 
               settings in the Windows registry. It has an 
               associated INI file that defines the settings to update

               Delphi. It customises a number of minor aspects of 
               the IDE (like the colour of tooltips, and the task bar 
               button caption)
