+      This package provides a high level object oriented wrapper around libgnutls,
+      as well as low level bindings to the GnuTLS types and functions via ctypes.
+      The high level wrapper hides the details of accessing the GnuTLS library via
+      ctypes behind a set of classes that encapsulate GnuTLS sessions, certificates
+      and credentials and expose them to python applications using a simple API.
+
+      The package also includes a Twisted interface that has seamless intergration
+      with Twisted, providing connectTLS and listenTLS methods on the Twisted
+      reactor once imported (the methods are automatically attached to the reactor
+      by simply importing the GnuTLS Twisted interface module).
+
+      The high level wrapper is written using the GnuTLS library bindings that are
+      made available via ctypes. This makes the wrapper very powerful and flexible
+      as it has direct access to all the GnuTLS internals and is also very easy to
+      extend without any need to write C code or recompile anything.
