synopsis: A client library for the D-Bus IPC system.
description:
    D-Bus is a simple, message-based protocol for inter-process
    communication, which allows applications to interact with other parts of
    the machine and the user's session using remote procedure calls.
    .
    D-Bus is a essential part of the modern Linux desktop, where it replaces
    earlier protocols such as CORBA and DCOP.
    .
    This library is an implementation of the D-Bus protocol in Haskell. It
    can be used to add D-Bus support to Haskell applications, without the
    awkward interfaces common to foreign bindings.
    .
    Example: connect to the session bus, and get a list of active names.
    .
    @
    {-\# LANGUAGE OverloadedStrings \#-}
    .
    import Data.List (sort)
    import DBus
    import DBus.Client
    .
    main = do
        client <- connectSession
        //
        \-- Request a list of connected clients from the bus
        reply <- call_ client (methodCall \"\/org\/freedesktop\/DBus\" \"org.freedesktop.DBus\" \"ListNames\")
            { methodCallDestination = Just \"org.freedesktop.DBus\"
            }
        //
        \-- org.freedesktop.DBus.ListNames() returns a single value, which is
        \-- a list of names (here represented as [String])
        let Just names = fromVariant (methodReturnBody reply !! 0)
        //
        \-- Print each name on a line, sorted so reserved names are below
        \-- temporary names.
        mapM_ putStrLn (sort names)
