gostan, a Malaysian slang word, meaning "go astern" or go backward is a file reverse reader The idea was borrowed from the 'tac' unix command. In short, it sets the file read position to the end of file and start looking for line separator (\n), fill the characters to buffer and output it as the pipe writer. So you need to create an io.Pipe() first and read the data stream from io.PipeReader
