+# Components Section - list of the modules and components that will be processed by compilation\r
+#                      tools and the EDK II tools to generate PE32/PE32+/Coff image files.\r
+#\r
+# Note: The EDK II DSC file is not used to specify how compiled binary images get placed\r
+#       into firmware volume images. This section is just a list of modules to compile from\r
+#       source into UEFI-compliant binaries.\r
+#       It is the FDF file that contains information on combining binary files into firmware\r
+#       volume images, whose concept is beyond UEFI and is described in PI specification.\r
+#       Binary modules do not need to be listed in this section, as they should be\r
+#       specified in the FDF file. For example: Shell binary (Shell_Full.efi), FAT binary (Fat.efi),\r
+#       Logo (Logo.bmp), and etc.\r
+#       There may also be modules listed in this section that are not required in the FDF file,\r
+#       When a module listed here is excluded from FDF file, then UEFI-compliant binary will be\r
+#       generated for it, but the binary will not be put into any firmware volume.\r
