20			`/// \par Overview`
21			`/// This library provides high-level functions for accessing the Dallas`
22			`/// Semiconductor DS1631 I2C Temperature Sensor.`
23			`///`
24			`/// The basic specs of the DS1631 are:`
25			`/// - operating temperature range -55 to +125 degrees C`
26			`/// - high accuracy of +/-0.5C over 0 to +70 degrees C`
27			`/// - 8 to 12-bit signed output`
28			`/// - thermostat functionality`
