title: Can I get pip to delete scripts that I installed but no longer want?
body: <p>Say I have the following project:</p>
  
  <pre><code>confectionary/
      __init__.py
      confections.py
  scripts/
      crunchy_frog.py
      anthrax_ripple.py
      spring_surprise.py
  </code></pre>
  
  <p>And it has been installed by my users, so they can simply type</p>
  
  <pre><code>$ spring_surprise.py
  </code></pre>
  
  <p>and have stainless steel bolts spring out of their computer, piercing both cheeks.</p>
  
  <p>However, Constable Parrot has convinced me to move into more <em>conventional</em> areas of confectionary, so I will no longer offer such sweetmeats. I have changed my scripts to look like this:</p>
  
  <pre><code>scripts/
     praline.py
     lime_coconut.py
  </code></pre>
  
  <p>Yet, when I install this newer version, the old scripts stay around.</p>
  
  <p>Is it possible to specify somehow in my setup.py that I no longer want these old scripts when my application is upgraded?</p>
