 It is an error to specify a BOARD_SEPOLICY_DIRS that has no entries when
 specifying BOARD_SEPOLICY_REPLACE.
 
-Example Usage:
+BOARD_SEPOLICY_IGNORE is a list of paths (directory + filename) of
+files that are not to be included in the resulting policy. This list
+is passed to filter-out to remove any paths you may want to ignore. This
+is useful if you have numerous config directories that contain a file
+and you want to NOT include a particular file in your resulting
+policy file, either by UNION or REPLACE.
+Eg.) Suppose the follwoing:
+     BOARD_SEPOLICY_DIRS := X Y
+     BOARD_SEPOLICY_REPLACE := A
+     BOARD_SEPOLICY_IGNORE := X/A
+
+     Directories X and Y contain A.
+
+     The resulting policy is created by using Y/A only, thus X/A was
+     ignored.
