+# Extra RecipeInfo will be all defined in this file. Currently,
+# Only Hob (Image Creator) Requests some extra fields. So
+# HobRecipeInfo is defined. It's named HobRecipeInfo because it
+# is introduced by 'hob'. Users could also introduce other
+# RecipeInfo or simply use those already defined RecipeInfo.
+# In the following patch, this newly defined new extra RecipeInfo
+# will be dynamically loaded and used for loading/saving the extra
+# cache fields
