+## @file
+# A hook-in library for:
+# - MdeModulePkg/Universal/Variable/Pei/VariablePei.inf
+# - MdeModulePkg/Universal/Variable/RuntimeDxe/VariableRuntimeDxe.inf
+# - MdeModulePkg/Universal/Variable/RuntimeDxe/VariableSmm.inf
+#
+# Plugging this library instance into one of the above modules makes that
+# variable service backend wait for another platform module to dynamically
+# initialize or verify EFI_FIRMWARE_VOLUME_HEADER and VARIABLE_STORE_HEADER in
+# the non-volatile variable store FVB device. The initialization / verification
+# is signaled by installing gEdkiiNvVarStoreFormattedGuid into the
+# phase-matching PPI or protocol database, with a NULL interface. (Note that
+# installing gEdkiiNvVarStoreFormattedGuid into either the DXE or the MM
+# protocol database will unblock VariableSmm -- refer to EFI_SECTION_MM_DEPEX
+# in the PI spec.)
