Reference Guide for Bonescript?

Is there a reference or guide to describe the features and function in Bonescript like Serial.read or the I2C functions? I searched and found a few examples but but nothing explaining the syntax and available features or how to use them. I have been taking examples trying them out and seeing how they work with some success but it seems like if I had a reference guide or book that describes the functions and options for each function and how to use them it might be easier to figure out how to do things.

Have you checked out http://www.amazon.com/Programming-BeagleBone-Black-JavaScript-BoneScript/dp/0071832122 ?

Yes I bought that book from Amazon and it has helped, it has working examples and a description of the specific code that is in the book but not a general description of the functions or other functions not used in the code examples.
