// Template IDL file for the Bho DLL. This template is a complete IDL file in
// all but one respect; it has one replaceable entry for the CLSID for
// BhoEntrypointClass. This template is processed by generate_oneclick_idl.py,
// which generates a GUID using UUIDGEN.EXE, and writes out a complete IDL
// file with the new CLSID.
//
// Background Information:
// We generate new CLSIDs for each fresh build of Omaha. This allows us to "hot
// swap" the BHO, and we don't face the issue of IE using the older version of
// the BHO unless it is restarted.

import "oaidl.idl";
import "ocidl.idl";

// MK keeps rebuilding unless there is an interface in the IDL file. Adding in a
// dummy interface.
