  Cross Platform Interface Description Language (XPIDL) is the interface definition language developed by Mozilla.org to specify XPCOM interfaces.
  
  It is similar to the Object Management Group's CORBA IDL.
  
  Mozilla provides a utility xpidl that converts the IDL files into XPCOM Type Library (.xpt) files.
