Module Name:\r
\r
  efildrimage.c\r
\r
Abstract:\r
\r
  Creates and EFILDR image.\r
  This tool combines several PE Image files together using following format denoted as EBNF:\r
  FILE := EFILDR_HEADER\r
          EFILDR_IMAGE +\r
          <PeImageFileContent> +\r
  The order of EFILDR_IMAGE is same as the order of placing PeImageFileContent.\r
