+==============================================================================
+1. Filename Convention					*mac-filename*
+
+Starting with Vim version 7 you can just use the unix path separators with
+Vim. In order to determine if the specified filename is relative to the
+current folder or absolute (i.e. relative to the "Desktop"), the following
+algorithm is used:
+
+	If the path start by a "/", the path is absolute
+	If the path start by a ":", the path is relative
+	If the path doesn't start by neither a "/" nor ":",
+	  and a ":" is found before a "/" then the path is absolute
+>
+		:e /HD/text
+		:e HD:text
+<	Edit the file "text" of the disk "HD" >
+		:e :src:main.c
+		:e src/main.c
+<	Edit the file "main.c" in the folder "src" in the current folder >
+		:e os_mac.c
+<	Edit the file "os_mac.c" in the current folder.
+
+You can use the |$VIM| and |$VIMRUNTIME|  variable. >
+
+		:so $VIMRUNTIME:syntax:syntax.vim
+
+==============================================================================
+2. .vimrc and .vim files				*mac-vimfile*
+
+It is recommended to use Unix style line separators for Vim scripts, thus a
+single newline character.
+
+When starting up Vim will load the $VIMRUNTIME/macmap.vim script to define
+default command-key mappings.
+
+On older systems files starting with a dot "." are discouraged, thus the rc
+files are named "vimrc" or "_vimrc" and "gvimrc" or "_gvimrc".  These files
+can be in any format (mac, dos or unix).  Vim can handle any file format when
+the |'nocompatible'| option is set, otherwise it will only handle mac format
+files.
+
+==============================================================================
+3. Mac FAQ						*mac-faq*
+
+On the internet:  http://macvim.org/OSX/index.php#FAQ
+
+Q: I can't enter non-ASCII character in Apple Terminal.
+A: Under Window Settings, Emulation, make sure that "Escape non-ASCII
+   characters" is not checked.
+
+Q: How do I start the GUI from the command line?
+A: Assuming that Vim.app is located in /Applications:
+	open /Applications/Vim.app
+   Or:
+	/Applications/Vim.app/Contents/MacOS/Vim -g  {arguments}
+
+Q: How can I set $PATH to something reasonable when I start Vim.app from the
+   GUI or with open?
+A: The following trick works with most shells.  Put it in your vimrc file.
+   This is included in the system vimrc file included with the binaries
+   distributed at macvim.org . >
+	let s:path = system("echo echo VIMPATH'${PATH}' | $SHELL -l")
+	let $PATH = matchstr(s:path, 'VIMPATH\zs.\{-}\ze\n')
+
+==============================================================================
+4. Mac Lack						*mac-lack*
+
+In a terminal CTRL-^ needs to be entered as Shift-Control-6.  CTRL-@ as
+Shift-Control-2.
+
+==============================================================================
+5. Mac Bug Report					*mac-bug*
+
+When reporting any Mac specific bug or feature change, please use the vim-mac
+maillist |vim-mac|.  However, you need to be subscribed.  An alternative is to
+send a message to the current MacVim maintainers:
+
+	mac@vim.org
+
+==============================================================================
+6. Compiling Vim					*mac-compile*
+
+See the file "src/INSTALLmac.txt" that comes with the source files.
