-- | Pulls in lots of useful modules for building and using Properties.
--
-- Propellor enures that the system it's run in satisfies a list of
-- properties, taking action as necessary when a property is not yet met.
--
-- A simple propellor program example:
--
-- > import Propellor
-- > import Propellor.CmdLine
-- > import qualified Propellor.Property.File as File
-- > import qualified Propellor.Property.Apt as Apt
-- >
-- > main :: IO ()
-- > main = defaultMain getProperties
-- >
-- > getProperties :: HostName -> Maybe [Property]
-- > getProperties "example.com" = Just
-- > [ Apt.installed ["mydaemon"]
-- > , "/etc/mydaemon.conf" `File.containsLine` "secure=1"
-- > `onChange` cmdProperty "service" ["mydaemon", "restart"]
-- > ]
-- > getProperties _ = Nothing
--
-- See config.hs for a more complete example, and clone Propellor's
-- git repository for a deployable system using Propellor:
-- git clone <git://git.kitenet.net/propellor>
