-1. Overview ~
-
-    The Haskell mode plugins provide advanced support for Haskell development
-    using GHC/GHCi on Windows and Unix-like systems. The functionality is
-    based on Haddock-generated library indices, on GHCi's interactive
-    commands, or on simply activating (some of) Vim's built-in program editing
-    support in Haskell-relevant fashion. These plugins live side-by-side with
-    the pre-defined |syntax-highlighting| support for |haskell| sources, and
-    any other Haskell-related plugins you might want to install (see
-    |haskellmode-resources|).
-
-    The Haskell mode plugins consist of three filetype plugins (haskell.vim,
-    haskell_doc.vim, haskell_hpaste.vim), which by Vim's |filetype| detection
-    mechanism will be auto-loaded whenever files with the extension '.hs' are
-    opened, and one compiler plugin (ghc.vim) which you will need to load from
-    your vimrc file (see |haskellmode-settings|).
-
-
-                                                    *haskellmode-requirements*
-1.1 Runtime Requirements ~
-
-    The plugins require a recent installation of GHC/GHCi. The functionality
-    derived from Haddock-generated library indices also requires a local
-    installation of the Haddock documentation for GHC's libraries (if there is

-2. Settings ~
-
-    The plugins try to find their dependencies in standard locations, so if
-    you're lucky, you will only need to set |compiler| to ghc, and configure
-    the location of your favourite web browser. You will also want to make
-    sure that |filetype| detection and |syntax| highlighting are on. Given the
-    variety of things to guess, however, some dependencies might not be found
-    correctly, or the defaults might not be to your liking, in which case you
-    can do some more fine tuning. All of this configuration should happen in
-    your |vimrc|.
->
-        " enable syntax highlighting
-        syntax on
- 
-        " enable filetype detection and plugin loading
-        filetype plugin on
-<
-
-                                                   *haskellmode-settings-main*
-2.1 GHC and web browser ~
-
-                                                 *compiler-ghc* *ghc-compiler*
-    To use the features provided by the GHC |compiler| plugin, use the
-    following |autocommand| in your vimrc:
->
-        au BufEnter *.hs compiler ghc
-<
-                                                                       *g:ghc*
-    If the compiler plugin can't locate your GHC binary, or if you have
-    several versions of GHC installed and have a preference as to which binary
-    is used, set |g:ghc|:
->
-        :let g:ghc="/usr/bin/ghc-6.6.1"
-<
-                                                           *g:haddock_browser*
-    The preferred HTML browser for viewing Haddock documentation can be set as
-    follows:
->
-        :let g:haddock_browser="/usr/bin/firefox"
-<
-
-                                                   *haskellmode-settings-fine*
-2.2 Fine tuning - more configuration options ~
-
-    Most of the fine tuning is likely to happen for the haskellmode_doc.vim
-    plugin, so you can check the current settings for this plugin via the
-    command |:DocSettings|. If all the settings reported there are to your
-    liking, you probably won't need to do any fine tuning.
-
-                                                *g:haddock_browser_callformat*
-    By default, the web browser|g:haddock_browser| will be started
-    asynchronously (in the background) on Windows or when vim is running in a
-    GUI, and synchronously (in the foreground) otherwise. These settings seem
-    to work fine if you are using a console mode browser (eg, when editing in
-    a remote session), or if you are starting a GUI browser that will launch
-    itself in the background. But if these settings do not work for you, you
-    can change the default browser launching behavior.
-
-    This is controlled by |g:haddock_browser_callformat|. It specifies a
-    format string which uses two '%s' parameters, the first representing the
-    path of the browser to launch, and the second is the documentation URL
-    (minus the protocol specifier, i.e. file://) passed to it by the Haddock
-    plugin.  For instance, to launch a GUI browser on Unix-like systems and
-    force it to the background (see also |shellredir|):
->
-        :let g:haddock_browser_callformat = '%s file://%s '.printf(&shellredir,'/dev/null').' &'
-<
-                                                            *g:haddock_docdir*
-    Your system's installed Haddock documentation for GHC and its libraries
-    should be automatically detected. If the plugin can't locate them, you
-    must point |g:haddock_docdir| to the path containing the master index.html
-    file for the subdirectories 'libraries', 'Cabal', 'users_guide', etc.:
->
-        :let g:haddock_docdir="/usr/local/share/doc/ghc/html/"
-<
-                                                      *g:haddock_indexfiledir*
-    The information gathered from Haddock's index files will be stored in a
-    file called 'haddock_index.vim' in a directory derived from the Haddock
-    location, or in $HOME. To configure another directory for the index file,
-    use: 
->
-        :let g:haddock_indexfiledir="~/.vim/"
-<
-                                                                      *g:wget*
-    If you also want to try the experimental hpaste functionality, you might
-    you need to set |g:wget| before the |hpaste| plugin is loaded (unless wget
-    is in your PATH):
->
-        :let g:wget="C:\Program Files\wget\wget.exe"
-<
-
-    Finally, the mappings actually use|<LocalLeader>|behind the scenes, so if
-    you have to, you can redefine|maplocalleader|to something other than '_'.
-    Just remember that the docs still refer to mappings starting with '_', to
-    avoid confusing the majority of users!-)

-3. GHC Compiler Integration ~
-
-    The GHC |compiler| plugin sets the basic |errorformat| and |makeprg| to
-    enable |quickfix| mode using GHCi, and provides functionality for show
-    info (|_si|), show type (|_t| or mouse |balloon|), add type declaration
-    (|_T|), create tag file (|_ct|), and insert-mode completion
-    (|i_CTRL-X_CTRL-O|) based on GHCi browsing of the current and imported
-    modules. 
-
-    To avoid frequent calls to GHCi, type information is cached in Vim. The
-    cache will be populated the first time a command depends on it, and will
-    be refreshed every time a |:make| goes through without generating errors
-    (if the |:make| does not succeed, the old types will remain available in
-    Vim).  You can also unconditionally force reloading of type info using
-    |:GHCReload| (if GHCi cannot load your file, the type info will be empty).
-
-
-    In addition to the standard|quickfix| commands, the GHC compiler plugin
-    provides:
-
-                                                                  *:GHCReload*
-:GHCReload              Reload modules and unconditionally refresh cache of
-                        type info. Usually, |:make| is prefered, as that will
-                        refresh the cache only if GHCi reports no errors, and
-                        show the errors otherwise.
-
-                                                           *:GHCStaticOptions*
-:GHCStaticOptions       Edit the static GHC options for the current buffer.
-                        Useful for adding hidden packages (-package ghc).
-
-                                                                       *:GHCi*
-:GHCi {command/expr}    Run GHCi commands/expressions in the current module.                  
-
-                                                                         *_ct*
-_ct                     Create |tags| file for the current Haskell source
-                        file. This uses GHCi's :ctags command, so it will work
-                        recursively, but will only list tags for exported
-                        entities.
-
-                                                                        *_opt*
-_opt                    Shows a menu of frequently used GHC compiler options 
-                        (selecting an entry adds the option as a pragma to the
-                        start of the file). Uses popup menu (GUI) or :emenu
-                        and command-line completion (CLI).
-
-                                                                       *_lang*
-_lang                   Shows a menu of the LANGUAGE options supported by GHC
-                        (selecting an entry adds the language as a pragma to 
-                        the start of the file). Uses popup menu (GUI) or
-                        :emenu and command-line completion (CLI).
-
-                                                                         *_si*
-_si                     Show extended information for the name under the
-                        cursor. Uses GHCi's :info command. Output appears in
-                        |preview-window| (when done, close with |:pclose|).
-
-                                                                          *_t*
-_t                      Show type for the name under the cursor. Uses cached
-                        info from GHCi's :browse command.
-
-                                                                          *_T*
-_T                      Insert type declaration for the name under the cursor.
-                        Uses cached info from GHCi's :browse command.
-
-                                *haskellmode-XO* *haskellmode-omni-completion*
-CTRL-X CTRL-O           Standard insert-mode omni-completion based on the
-                        cached type info from GHCi browsing current and
-                        imported modules. Only names from the current and from
-                        imported modules are included (the completion menu
-                        also show the type of each identifier).

-4. Haddock Integration ~
-
-    Haskell mode integrates with Haddock-generated HTML documentation,
-    providing features such as navigating to the Haddock entry for the
-    identifier under the cursor (|_?|), completion for the identifier under
-    the cursor (|i_CTRL-X_CTRL-U|), and adding import statements (|_i| |_im|
-    |_iq| |_iqm|) or module qualifier (|_.|) for the identifier under the
-    cursor.
-
-    These commands operate on an internal Haddock index built from the
-    platform's installed Haddock documentation for GHC's libraries. Since
-    populating this index takes several seconds, it should be stored as a 
-    file called 'haddock_index.vim' in the directory specified by
-    |g:haddock_indexfiledir|.
-
-    Some commands present a different interface (popup menu or command-line
-    completion) according to whether the current Vim instance is graphical or
-    console-based (actually: whether or not the GUI is running). Such
-    differences are marked below with the annotations (GUI) and (CLI),
-    respectively.
-
-    |:DocSettings| shows the settings for this plugin. If you are happy with
-    them, you can call |:ExportDocIndex| to populate and write out the
-    documentation index (should be called once for every new version of GHC).
-

-CTRL-X CTRL-U           User-defined insert mode name completion based on all
-                        names known to the Haddock index, including package
-                        names. Completions are presented in a popup menu which
-                        also displays the fully qualified module from which
-                        each entry may be imported.

-                        CamelCode shortcuts are supported, meaning that
-                        lower-case letters can be elided, using only
-                        upper-case letters and module qualifier separators (.)
-                        for disambiguation:

-
-                        To reduce unwanted matches, the first letter of such
-                        shortcuts and the first letter after each '.' have to
-                        match directly.

-5. Hpaste Integration ~
-
-    This experimental feature allows browsing and posting to
-    http://hpaste.org, a Web-based pastebin tailored for Haskell code.
-
-
-                                                                *:HpasteIndex*
-:HpasteIndex            Read the most recent entries from hpaste.org. Show an
-                        index of the entries in a new buffer, where ',r' will
-                        open the current highlighted entry [and ',p' will
-                        annotate it with the current buffer].

-                                                              *:HpastePostNew*
-:HpastePostNew          Submit current buffer as a new hpaste entry.
-                        [This, and ',p' above, are temporarily disabled, 
-                         needs update to new hpaste.org layout]

-6. Additional Resources ~
-
-    An quick screencast tour through of these plugins is available at:
-
-    http://projects.haskell.org/haskellmode-vim/screencasts.html
-
-    Other Haskell-related Vim plugins can be found here:
-
-    http://www.haskell.org/haskellwiki/Libraries_and_tools/Program_development#Vim
-
-    Make sure to read about Vim's other program-editing features in its online
-    |user-manual|. Also have a look at Vim tips and plugins at www.vim.org -
-    two other plugins I tend to use when editing Haskell are AlignPlugin.vim
-    (to line up regexps for definitions, keywords, comments, etc. in
-    consecutive lines) and surround.vim (to surround text with quotes,
-    brackets, parentheses, comments, etc.).
