16			`/// \par Overview`
17			`/// This library provides a very simple bit-banged I2C serial interface.`
18			`/// The library supports MASTER mode send and receive of single or multiple`
19			`/// bytes. Thanks to the standardization of the I2C protocol and register`
20			`/// access, the send and receive commands are everything you need to talk to`
21			`/// thousands of different I2C devices including: EEPROMS, Flash memory,`
22			`/// MP3 players, A/D and D/A converters, electronic potentiometers, etc.`
23			`///`
24			`/// Although some AVR processors have built-in hardware to help create an I2C`
25			`/// interface, this library does not require or use that hardware.`
26			`///`
27			`/// For general information about I2C, see the i2c library.`
