title: py2exe "include" modules: when should they be managed manually?
body: <p>When is it necessary to specify modules to include? Doesn't py2exe search and include whatever is needed per: <a href="http://www.py2exe.org/index.cgi/FAQ" rel="noreferrer">http://www.py2exe.org/index.cgi/FAQ</a>?</p>
  
  <p>And why does it include modules that are not being used, such as ["Tkconstants", "Tkinter", "tcl", "wx"] (I'm using Qt, but have wx installed on my PC) that then need to be excluded?</p>
