//  3. Click on Add...
//  4. Type  MIDL.EXE  and click OK (or press ENTER)
//  5. Fill in definition of a new tool as follows:
//      Menu Text:      Compile &IDL file
//      Command:        MIDL.EXE
//      Arguments:      /ms_ext /char unsigned /c_ext $(FileName)$(FileExt)
//      Initial Dir:    $(FileDir)
//  6. Click on Close
//
//  Having done this, you can now use MSDEV to compile IDL files (such as
//  this one).  Just open the file and select Tools/Compile IDL file.
