Understanding the /x/net/context module

I'm using and reading through the etcd code, and in particular this module:

https://godoc.org/golang.org/x/net/context

comes up a lot. I don't quite understand what it's used for, and if someone could explain this a bit better and/or point me to some good resources on the topic I'd appreciate it.

Thanks and happy new year.

http://blog.golang.org/context would be a good place to start. It's linked from the context package docs.

I don't know how I missed that, thanks! I'll take a read.
