# Script for building the _ssl module for Windows.

# and build OpenSSL, then invokes a simple nmake session
# for _ssl.pyd itself.
# 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 PC/VC6 directory.
#
# it should configure and build SSL, then build the ssl Python extension
# without intervention.
