+# 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 PCBuild directory.
+#
+# it should configure and build SSL, then build the ssl Python extension
+# without intervention.
