- # Script for building the _ssl module for Windows.
- # Uses Perl to setup the OpenSSL environment correctly
- # 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.
