-# If you don't need to do a full clean build but would like to touch
-# a file or delete some intermediate files, add a clean step to the end
-# of the list.  These steps will only be run once, if they haven't been
-# run before.
-#
-# E.g.:
-#     $(call add-clean-step, touch -c external/sqlite/sqlite3.h)
-#     $(call add-clean-step, rm -rf $(PRODUCT_OUT)/obj/STATIC_LIBRARIES/libz_intermediates)
-#
-# Always use "touch -c" and "rm -f" or "rm -rf" to gracefully deal with
-# files that are missing or have been moved.
-#
-# Use $(PRODUCT_OUT) to get to the "out/target/product/blah/" directory.
-# Use $(OUT_DIR) to refer to the "out" directory.
-#
-# If you need to re-do something that's already mentioned, just copy
-# the command and add it to the bottom of the list.  E.g., if a change
-# that you made last week required touching a file and a change you
-# made today requires touching the same file, just copy the old
-# touch step and add it to the end of the list.
-#
-# ************************************************
-# NEWER CLEAN STEPS MUST BE AT THE END OF THE LIST
-# ************************************************
-
-# For example:
-#$(call add-clean-step, rm -rf $(OUT_DIR)/target/common/obj/APPS/AndroidTests_intermediates)
-#$(call add-clean-step, rm -rf $(OUT_DIR)/target/common/obj/JAVA_LIBRARIES/core_intermediates)
-#$(call add-clean-step, find $(OUT_DIR) -type f -name "IGTalkSession*" -print0 | xargs -0 rm -f)
