from streams session

• end-of-stream - specify a callback to be called when a stream ends (which is surpsingly hard to get right)
• duplexify - compose a Duplex stream from a Readable and a Writable stream
• pump - pipe streams together and close all of them if one of them closes
• pumpify - combine an array of streams into a single duplex stream using pump and duplexify
• through2 - tools for making Transform streams
• from2 - tools for making Readable streams
