-# Script for building the _ssl and _hashlib modules for Windows.
-# Uses Perl to setup the OpenSSL environment correctly
-# and build OpenSSL, then invokes a simple nmake session
-# for the actual _ssl.pyd and _hashlib.pyd DLLs.
-
-# THEORETICALLY, you can:
-# * Unpack the latest SSL release one level above your main Python source
-# directory. It is likely you will already find the zlib library and
-# any other external packages there.
-# * Install ActivePerl and ensure it is somewhere on your path.
-# * Run this script from the PCBuild directory.
-#
-# it should configure and build SSL, then build the _ssl and _hashlib
-# Python extensions without intervention.
-
-# Modified by Christian Heimes
-# Now this script supports pre-generated makefiles and assembly files.
-# Developers don't need an installation of Perl anymore to build Python. A svn
-# checkout from our svn repository is enough.
-#
-# In Order to create the files in the case of an update you still need Perl.
-# Run build_ssl in this order:
-# python.exe build_ssl.py Release x64
-# python.exe build_ssl.py Release Win32
