==============================================================================
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.
