1	n/a	# Script for building the _ssl module for Windows.
2	n/a	# Uses Perl to setup the OpenSSL environment correctly
3	n/a	# and build OpenSSL, then invokes a simple nmake session
4	n/a	# for _ssl.pyd itself.

6	n/a	# THEORETICALLY, you can:
7	n/a	# * Unpack the latest SSL release one level above your main Python source
8	n/a	# directory. It is likely you will already find the zlib library and
9	n/a	# any other external packages there.
10	n/a	# * Install ActivePerl and ensure it is somewhere on your path.
11	n/a	# * Run this script from the PC/VC6 directory.

13	n/a	# it should configure and build SSL, then build the ssl Python extension
