5 |
|

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

12 | #
|

13 | # it should configure and build SSL, then build the _ssl and _hashlib

14 | # Python extensions without intervention.
