+/**
+ * CloseGuard is a mechanism for flagging implicit finalizer cleanup of
+ * resources that should have been cleaned up by explicit close
+ * methods (aka "explicit termination methods" in Effective Java).
+ * <p>
+ * A simple example: <pre>   {@code
+ *   class Foo {
+ *
+ *       private final CloseGuard guard = CloseGuard.get();
+ *
+ *       ...
+ *
+ *       public Foo() {
+ *           ...;
+ *           guard.open("cleanup");
+ *       }
+ *
+ *       public void cleanup() {
+ *          guard.close();
+ *          ...;
+ *          if (Build.VERSION.SDK_INT >= 28) {
+ *              Reference.reachabilityFence(this);
+ *          }
+ *          // For full correctness in the absence of a close() call, other methods may also need
+ *          // reachabilityFence() calls.
+ *       }
+ *
+ *       protected void finalize() throws Throwable {
+ *           try {
+ *               // Note that guard could be null if the constructor threw.
+ *               if (guard != null) {
+ *                   guard.warnIfOpen();
+ *               }
+ *               cleanup();
+ *           } finally {
+ *               super.finalize();
+ *           }
+ *       }
+ *   }
+ * }</pre>
+ *
+ * In usage where the resource to be explicitly cleaned up is
+ * allocated after object construction, CloseGuard protection can
+ * be deferred. For example: <pre>   {@code
+ *   class Bar {
+ *
+ *       private final CloseGuard guard = CloseGuard.get();
+ *
+ *       ...
+ *
+ *       public Bar() {
+ *           ...;
+ *       }
+ *
+ *       public void connect() {
+ *          ...;
+ *          guard.open("cleanup");
+ *       }
+ *
+ *       public void cleanup() {
+ *          guard.close();
+ *          ...;
+ *          if (Build.VERSION.SDK_INT >= 28) {
+ *              Reference.reachabilityFence(this);
+ *          }
+ *          // For full correctness in the absence of a close() call, other methods may also need
+ *          // reachabilityFence() calls.
+ *       }
+ *
+ *       protected void finalize() throws Throwable {
+ *           try {
+ *               // Note that guard could be null if the constructor threw.
+ *               if (guard != null) {
+ *                   guard.warnIfOpen();

+ *               super.finalize();
+ *           }
+ *       }
+ *   }
+ * }</pre>
+ *
+ * When used in a constructor, calls to {@code open} should occur at
+ * the end of the constructor since an exception that would cause
+ * abrupt termination of the constructor will mean that the user will
+ * not have a reference to the object to cleanup explicitly. When used
+ * in a method, the call to {@code open} should occur just after

-# 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

-# If you need to re-do something that's already mentioned, just copy
