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