title: why do I keep getting this message when installing saying EntryPoint must be in 'name=module:attrs [extras]
body: <p>Hi I am on OSx Mavericks, using python 2.7 and pip version 6.0.8 and setuptools version 12.2.</p>
  
  <p>When I try to install my project I get warning messages but installs successfully</p>
  
  <pre><code>$ python setup.py install --user
  </code></pre>
  
  <p>if I use distutils I get below message which probably its setup doesn't have kwarg entry_points.
      /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/distutils/dist.py:
      267: UserWarning: Unknown distribution option: 'entry_points'
        warnings.warn(msg)</p>
  
  <p>but when I try to install using pip the following way, I get below error messages and install doesn't continues:</p>
  
  <pre><code>$ pip install --user --editable .
  </code></pre>
  
  <p>if I use pip even if I have distutils setup imported I get the below error message.</p>
  
  <pre><code>Obtaining file:///Users/Me/Development/pyclones/git-maildiff
      error in maildiff setup command: ("EntryPoint must be in 'name=module:attrs [extras]' format", 'git-maildiff=scripts.git-maildiff')
      Complete output from command python setup.py egg_info:
      error in maildiff setup command: ("EntryPoint must be in 'name=module:attrs [extras]' format", 'git-maildiff=scripts.git-maildiff')
  
      ----------------------------------------
      Command "python setup.py egg_info" failed with error code 1 in /Users/Me/Development/pyclones/git-maildiff
  </code></pre>
  
  <p>whilst I have call to setup like this </p>
  
  <pre><code>setup(
      name='maildiff',
      version=VERSION,
      author='Sanjeev Kumar',
      author_email='myemail@gmail.com',
      packages=['emaildiff', 'emaildiff/mail',],
      py_modules=['maildiff_cmd', 'version', 'send'],
      data_files = ['VERSION'],
      scripts=['scripts/git-maildiff'],
      license='LICENSE',
      description='Package to email color git diff',
      long_description=open('README.md').read(),
      entry_points={
      'console_scripts':
          ['git-maildiff=scripts.git-maildiff']
                  }
  )
  </code></pre>
  
  <p>can anyone help me why I am getting this,  I prefer to go with pip because i can use pip to uninstall it later, but I think their isn't any command like setup.py uninstall or remove.</p>
