fs-backwards-stream

exact same api as fs.createReadStream except reads chunks backwards. similar to fs-reverse except doesnt parse lines.

Stream data from start to end. if start is less than end they are switched rather then just not being useful.

var backwardsStream = require('fs-backwards-stream')

var s = backwardsStream(filename)

s.on('data',function(buf){
  console.log(buf.toString());
})
