title: Bookdown stand alone gitbook with separate pages
body: <p>I'm not sure if bookdown supports what I'm looking for as I am unable to find out how to do it. I would like to create a gitbook format as a standalone html file, but I want each chapter/section to be it's own page rather than it creating one very long page.</p>
  
  <p>Take the following code:</p>
  
  <pre><code>---
  title: "A Book"
  author: "nook"
  documentclass: krantz
  output:
    bookdown::gitbook:
      split_by: none
      self_contained: true
      keep_md: true
  ---
  
  ```{r setup, include=FALSE}
  knitr::opts_chunk$set(echo = TRUE)
  ```
  
  # Hello World
  
  Hi.
  
  Bye.
  
  # Hello World 2
  
  Hi.
  
  Bye.
  </code></pre>
