title: Copy an entire folder in a setup.py file
body: <p>I have a python application (mainly done using pyqt). I am using py2exe to create the executable, my setup.py looks like this</p>
  
  <pre><code>from distutils.core import setup import py2exe import os 
  includes=["sqlite3","sip","PyQt4","PyQt4.QtGui","PyQt4.QtCore"]
  excludes=[] 
  packages=[] 
  dll_excludes=['libgdk-win32-1.0-0.dll', 'libgobject-2.0-0.dll', 'tcl84.dll', 'tk84.dll']
  
  setup(
  
        options={"py2exe": {"compressed": 2,
                            "optimize": 2,
                            "includes": includes,
                            "excludes": excludes,
                            "packages": packages,
                            "dll_excludes": dll_excludes,
                            "bundle_files": 2,
                            "dist_dir": "dist",
                            "xref": False,
                            "skip_archive": False,
                            "ascii": False,
                            "custom_boot_script": '',
                            }
                 },
        windows=['myapplication.py'],
        data_files = [('', [r'c:\configuration.ini',
                            r'c:readme.txt'
                            ])]
  
        )
  </code></pre>
  
  <p>Now the data_files entry allows me to copy a few files to the 'dist' folder, however I would also like to copy my documentation folder, the documentation folder includes a whole bunch of files, html,images,pdfs, about 2MB of documentation stored in a my_app\docs folder. I am not sure how to do this. Can anyone suggest how?</p>
