+ This driver uses the EFI_FIRMWARE_VOLUME2_PROTOCOL to expose files in firmware
+ volumes via the the EFI_SIMPLE_FILESYSTEM_PROTOCOL and EFI_FILE_PROTOCOL.
+
+ It will expose a single directory, containing one file for each file in the firmware
+ volume. If a file has a UI section, its contents will be used as a filename.
+ Otherwise, a string representation of the GUID will be used.
+ Files of an executable type (That is PEIM, DRIVER, COMBINED_PEIM_DRIVER and APPLICATION)
+ will have ".efi" added to their filename.
+
+ Its primary intended use is to be able to start EFI applications embedded in FVs
+ from the UEFI shell. It is entirely read-only.
