+# 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)

+There are implementations of 5 classes in this file:
+LocTimer, LocTimerDelegate, LocTimerContainer, LocTimerPollTask, LocTimerWrapper
+
+LocTimer - client front end, interface for client to start / stop timers, also
+           to provide a callback.
+LocTimerDelegate - an internal timer entity, which also is a LocRankable obj.
+                   Its life cycle is different than that of LocTimer. It gets
+                   created when LocTimer::start() is called, and gets deleted
+                   when it expires or clients calls the hosting LocTimer obj's
+                   stop() method. When a LocTimerDelegate obj is ticking, it
+                   stays in the corresponding LocTimerContainer. When expired
+                   or stopped, the obj is removed from the container. Since it
+                   is also a LocRankable obj, and LocTimerContainer also is a
+                   heap, its ranks() implementation decides where it is placed
+                   in the heap.
+LocTimerContainer - core of the timer service. It is a container (derived from
+                    LocHeap) for LocTimerDelegate (implements LocRankable) objs.
+                    There are 2 of such containers, one for sw timers (or Linux
+                    timers) one for hw timers (or Linux alarms). It adds one of
+                    each (those that expire the soonest) to kernel via services
+                    provided by LocTimerPollTask. All the heap management on the
+                    LocTimerDelegate objs are done in the MsgTask context, such
+                    that synchronization is ensured.
+LocTimerPollTask - is a class that wraps timerfd and epoll POXIS APIs. It also
+                   both implements LocRunnalbe with epoll_wait() in the run()
+                   method. It is also a LocThread client, so as to loop the run
+                   method.
+LocTimerWrapper - a LocTimer client itself, to implement the existing C API with
+                  APIs, loc_timer_start() and loc_timer_stop().
