{-# LANGUAGE PackageImports #-}

-- | Pulls in lots of useful modules for building and using Properties.
-- 
-- When propellor runs on a Host, it ensures that its list of Properties
-- is satisfied, taking action as necessary when a Property is not
-- currently satisfied.
--
-- 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 hosts
-- > 
-- > hosts :: [Host]
-- > hosts =
-- >   [ host "example.com"
-- >     & Apt.installed ["mydaemon"]
-- >     & "/etc/mydaemon.conf" `File.containsLine` "secure=1"
-- >       `onChange` cmdProperty "service" ["mydaemon", "restart"]
-- >     ! Apt.installed ["unwantedpackage"]
-- >   ]
--
-- 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>
