# The "It's like I have a shotgun in my mouth, I've got my finger on the
# trigger, and I like the taste of the gunmetal." release.
#
#
# - Implemented dispatcher (God help us)
# - Added DNS module into our tree. It's not a standard python module and
#   may not be available on the target system or may be outdated.
#   Don't want silly question about where to get this. Plus the default
#   version with python2.3 gives a deprecation warning because someone
#   put his name in there using latin2 chars and forgot to set the file
#   encoding. The warning is harmless, but users will ask what is that about
#   every 5 minutes a f---ing day.
# - Moved all python files that are not executed directly into modules/
# - Separated extended option class into a module
# - New Option type: server address (TCP/IP address or Unix socket)
# - Return IP and port in answers to be able to work remotely.
