access multiple buffers with Buffer interface - Node.js module
bl is a storage object for collections of Node.js Buffers, exposing them with the main Buffer readable API. Also works as a duplex stream so you can collect buffers from a stream that emits them and emit buffers to a stream that consumes them.
Node.js is an event-based server-side JavaScript engine.
