title: How to get access to long_description in setup after installation using pip?
body: <p>In the Python packaging <a href="https://github.com/pypa/sampleproject" rel="nofollow noreferrer">sampleproject</a> there is a long description for the module, given in <code>setup.py</code> using:</p>
  
  <pre><code># Get the long description from the README file
  with open(path.join(here, 'README.rst'), encoding='utf-8') as f:
      long_description = f.read()
  ...
  setup(
  ...
      # This is an optional longer description of your project that represents
      # the body of text which users will see when they visit PyPI.
      #
      # Often, this is the same as your README, so you can just read it in from
      # that file directly (as we have already done above)
      #
      # This field corresponds to the "Description" metadata field:
      # https://packaging.python.org/specifications/core-metadata/#description-optional
      long_description=long_description,  # Optional
  </code></pre>
  
  <p>How can the user get access to this descprtion, maybe in different format, after the module is installed with <code>pip install sampleproject</code>?</p>
