Split (matcher)

Break up a stream and reassemble it so that each line is a chunk. matcher may be a String, or a RegExp

Example, read every line in a file ...

  fs.createReadStream(file)
    .pipe(split())
    .on('data', function (line) {
      //each chunk now is a seperate line!
    })

split takes the same arguments as string.split except it defaults to '\n' instead of ',', and the optional limit paremeter is ignored. String#split
