Python wrapper around the OpenSSL library

 High-level wrapper around a subset of the OpenSSL library, includes
 .
   * SSL.Connection objects, wrapping the methods of Python's portable
     sockets
   * Callbacks written in Python
   * Extensive error-handling mechanism, mirroring OpenSSL's error
     codes
 .
 A lot of the object methods do nothing more than calling a
 corresponding function in the OpenSSL library.
