-""" A wrapper for the 'gpg' command::
-
-Portions of this module are derived from A.M. Kuchling's well-designed
-GPG.py, using Richard Jones' updated version 1.3, which can be found
-in the pycrypto CVS repository on Sourceforge:
-
-http://pycrypto.cvs.sourceforge.net/viewvc/pycrypto/gpg/GPG.py
-
-This module is *not* forward-compatible with amk's; some of the
-old interface has changed.  For instance, since I've added decrypt
-functionality, I elected to initialize with a 'gnupghome' argument
-instead of 'keyring', so that gpg can find both the public and secret
-keyrings.  I've also altered some of the returned objects in order for
-the caller to not have to know as much about the internals of the
-result classes.
-
-While the rest of ISconf is released under the GPL, I am releasing
-this single file under the same terms that A.M. Kuchling used for
-pycrypto.

-
-This version of the module has been modified from Steve Traugott's version
-(see http://trac.t7a.org/isconf/browser/trunk/lib/python/isconf/GPG.py) by
-Vinay Sajip to make use of the subprocess module (Steve's version uses os.fork()
-and so does not work on Windows). Renamed to gnupg.py to avoid confusion with
-the previous versions.
-
-Modifications Copyright (C) 2008-2012 Vinay Sajip. All rights reserved.
-
-A unittest harness (test_gnupg.py) has also been added.

-        Transition from the given `from_state` to the given `to_state`.
-        This method will return `True` if the state machine is now in `to_state`.  It
-        will return `False` if a timeout occurred the transition did not occur.
-        If `wait` is 0 (the default,) this method returns immediately if the state machine
-        is not in `from_state`.
-
-        If you want the thread to block and transition once the state machine to enters
-        `from_state`, set `wait` to a non-negative value.  Note there is no 'block
-        indefinitely' flag since this leads to deadlock.  If you want to wait indefinitely,
-        choose a reasonable value for `wait` (e.g. 20 seconds) and do so in a while loop like so:
-
-        ::
-
-            while not thread_should_exit and not state_machine.transition('disconnected', 'connecting', wait=20 ):
-                    pass # timeout will occur every 20s unless transition occurs
-            if thread_should_exit: return
-            # perform actions here after successful transition
-
-        This allows the thread to be responsive by setting `thread_should_exit=True`.
-
-        The optional `func` argument allows the user to pass a callable operation which occurs
-        within the context of the state transition (e.g. while the state machine is locked.)
-        If `func` returns a True value, the transition will occur.  If `func` returns a non-
-        True value or if an exception is thrown, the transition will not occur.  Any thrown
-        exception is not caught by the state machine and is the caller's responsibility to handle.
-        If `func` completes normally, this method will return the value returned by `func.`  If
-        values for `args` and `kwargs` are provided, they are expanded and passed like so:
-        `func( *args, **kwargs )`.
