  // Step #3 ... Use mscorpe.dll APIs
  pfnCreateICeeFileGen(...);    // Get a ICeeFileGen
  
  CreateCeeFile(...);           // Get a HCEEFILE (called for every output file needed)
  SetOutputFileName(...);       // Set the name for the output file
  pEmit = IMetaDataEmit object; // Get a metadata emitter
  GetSectionBlock(...);, AddSectionReloc(...); ... // Get blocks, write non-metadata information, and add necessary relocation
  EmitMetaDataEx(pEmit);        // Write out the metadata
  GenerateCeeFile(...);         // Write out the file. Implicitly calls LinkCeeFile and FixupCeeFile
