ATtiny84 I2C Master Library

I'm having trouble finding a library that will allow me to use an ATtiny84 as an I2C master.

There's a library here for the ATtiny85 here:
http://playground.arduino.cc/Code/USIi2c

And it branches off to another library to use an 84 as an I2C slave here:

But I haven't found a way to use it as a master. Can someone point me in the right direction? This subject is very new to me.

For what it's worth, I've already updated to the core found here:
http://code.google.com/p/arduino-tiny/

Here is an example sketch using the above library and an I2C RTC.

Thanks Jack, my code is compiling now. This gives me something to work with. 8)

By chance, is there something similar for SPI?

Good deal!
