How to share functions between notebooks?

So I did this notebook, with a bunch of utility functions dealing with Rotation Vectors… (something like quaternions, but not)

I would like to then use these in other notebooks with a minimum of boilerplate… how do I export a set of functions and import them somewhere else?

An easy way to do that is to add this to the notebook and evaluate it once.

SetOptions[EvaluationNotebook[], AutoGeneratedPackage -> Automatic]

Set the cells of functions you want to export as Initialization cells. With that setup, whenever you save the notebook a corresponding .m file is created with the exported functions. To use them in a different notebook, use Get to load the .m file.
