Synopsis:       A command-line interface for user input, written in Haskell.
Description:
                Haskeline provides a user interface for line input in command-line
                programs.  This library is similar in purpose to readline, but since
                it is written in Haskell it is (hopefully) more easily used in other
                Haskell programs.
                .
                Haskeline runs both on POSIX-compatible systems and on Windows.

-- There are three main advantages to the terminfo backend over the portable,
-- "dumb" alternative.  First, it enables more efficient control sequences
-- when redrawing the input.  Second, and more importantly, it enables us
-- to draw on multiple lines, so we can wrap long input strings.  And third,
-- the backend adds some extra key sequences such as forwards delete.
--
-- (The "dumb" terminal also allows editing of long input strings, but is
-- restricted to only one line and thus only shows part of the input at once.)
flag terminfo
    Description: Use the terminfo package for POSIX consoles.
    Default: True
    Manual: True

-- Help the GHC build by making it possible to disable the extra binary.
-- TODO: Make GHC handle packages with both a library and an executable.
flag examples
    Description: Enable executable components used for tests.
    Default: True
    Manual: True

Library
    -- We require ghc>=7.4.1 (base>=4.5) to use the base library encodings, even
