* Mostly tightening up the details on the hkp4py example script.
* Also fixed a typo in the LGPL boiler plate text included in all the

* lang/python/examples/howto/symcrypt-file.py: *sigh*; passphrase was
right the first time, just the error check that wasn't.
* I really should stop second guessing myself one of these days ...
