-// Arduino DS3232RTC Library
-// https://github.com/JChristensen/DS3232RTC
-// Copyright (C) 2018 by Jack Christensen and licensed under

-// Arduino library for the Maxim Integrated DS3232 and DS3231
-// Real-Time Clocks.
-// Requires PJRC's improved version of the Arduino Time Library,
-// https://playground.arduino.cc/Code/Time
-// https://github.com/PaulStoffregen/Time
-//
-// For AVR architecture, a DS3232RTC object named RTC is instantiated
-// by the library and I2C initialization occurs in the constructor;
-// this is for backwards compatibility.
-// For other architectures, the user needs to instantiate a DS3232RTC
-// object and optionally initialize the I2C bus by calling
-// DS3232RTC::begin(). The constructor has an optional bool parameter
-// to indicate whether I2C initialization should occur in the
-// constructor; this parameter defaults to true if not given.
-
-// define release-independent I2C functions
