title: How to save a custom categorized corpus in NLTK
body: <p>How can one 'save' a new corpus to NLTK corpora data?</p>
  
  <p>In my case, after I created a new custom categorized corpus in NLTK just like in this page said: <a href="https://stackoverflow.com/questions/10463898/creating-a-custom-categorized-corpus-in-nltk-and-python">Creating a custom categorized corpus in NLTK and Python</a></p>
  
  <p>I want to use it just like an already-installed corpora in NLTK (say movie_reviews). How can I do this? In other words, how can the new corpus I have read (say movie_reviews_0) can be called like this:</p>
  
  <pre><code>&gt;&gt;&gt; import nltk
  &gt;&gt;&gt; from nltk.corpus import movie_reviews_0
  </code></pre>
