title: What is the purpose of python 2.7's download package "Windows x86 MSI program database"?
body: <p>Upgrading from python 2.5/2.6 to python 2.7 on WinXP, I've found new download package forms for python at <a href="http://www.python.org/download/releases/2.7.1/" rel="noreferrer">http://www.python.org/download/releases/2.7.1/</a>.</p>
  
  <p>So I'm wondering what is the purpose of python 2.7's download package "<a href="http://www.python.org/ftp/python/2.7.1/python-2.7.1-pdb.zip" rel="noreferrer">Windows x86 MSI program database</a>"? Searching on web didn't bring me clarifications on this.</p>
  
  <p>Actually it contains lots for .pdb library files, which on my PC are associated to Palm PDB files. This should be false, as Palm OS is dead.</p>
