Node.js IPC tutoruals
There are several cluster/IPC libraries for node.js like multi node or node cluster. I'd like to figure out how they work, but there is lack of good tutorials/docs/manuals about IPC in node.js. Without them it is kind of hard to read all this barely commented and documented source code for a new person in node.js like me. Can someone provide some links to tutorials or docs if there any of them exists?

Thanks in advance for your answers.
