+  The contents of this directory are the examples included in the /GNU
+  Privacy Guard (GnuPG) Made Easy Python Bindings HOWTO/ file.  Each
+  script is explicitly for Python 3 and specifically for Python 3.4 or
+  later.
+
+  Some of these scripts may work with Python 2.7, but there are no
+  guarantees.  They will include the relevant imports from the
+ =__future__= module to facilitate that if possible.
