+" iptables-save/restore syntax highlighter
+"
+" Language:	   iptables-save/restore file
+" Version:     Not Specified
+" Date:        07-Jun-2014
+" Maintainer:  Eric Haarbauer <ehaar70{AT}gmail{DOT}com>
+" License:     This file is placed in the public domain.

+"============================================================================
+"
+" This vim syntax script highlights files used by Harald Welte's iptables-save
+" and iptables-restore utilities.  Both utilities are part of the iptables
+" application (http://www.netfilter.org/projects/iptables).
+" 
+" Features:
+"
+"   * Distinguishes commands, options, modules, targets and chains.
+"   * Distinguishes numeric IP addresses from net masks.
+"   * Highlights tokens that occur only in hand-edited files; for example,
+"     "--append" and "destination-unreachable".
+"   * Special handling for module names; for example, the tcp module is
+"     colored differently from the tcp protocol.
+"
+" Options:
+"
+"   Customize the behavior of this script by setting values for the following
+"   options in your .vimrc file.  (Type ":h vimrc" in vim for more information
+"   on the .vimrc file.)
+"
+"   g:Iptables_SpecialDelimiters
+"     This variable, if set to a non-zero value, distinguishes numeric
+"     delimiters, including the dots in IP addresses, the slash that separates
+"     an IP address from a netmask, and the colon that separates the ends of a
+"     port range.  If not set, this option defaults to off.
+"
+" Known Issues:
+"
+"   * Some special argument tokens are highlighted whether or not they are
+"     used with the correct option.  For example, "destination-unreachable"
+"     gets special highlighting whether or not is used as an argument to the
+"     --icmp-type option.  In practice, this is rarely a problem.
+"
+" Reporting Issues:
+"
+"   If you discover an iptables file that this script highlights incorrectly,
+"   please email the author (address at the top of the script) with the
+"   following information:
+"
+"     * Problem iptables file WITH ANY SENSITIVE INFORMATION REMOVED
+"     * The release version of this script (see top of the script)
+"     * If possible, a patch to fix the problem
+"
+" Design Notes:
+"
+"   Part of this script is autogenerated from the output of the iptables man
+"   page.  The source code for generating the script is available from the
+"   author on request (see email address at the top of the script).  The
+"   script should build from source on most Linux systems with iptables
+"   installed.
+"
+"   The build system that generates this script strips special CVS tokens
+"   (like "Id:") so that CVS no longer recognizes them.  This allows users to
+"   place the script in their own version control system without losing
+"   information.  The author encourages other vim script developers to adopt a
+"   similar approach in their own scripts.
+"
+" Installation:
+"
+"   Put this file in your user runtime syntax directory, usually ~/.vim/syntax
+"   in *NIX or C:\Program Files\vim\vimfiles\syntax in Windows.  Type ":h
+"   syn-files" from within vim for more information.
+"
+"   The iptables-save and iptables-restore applications do not specify a
+"   naming standard for the files they use.  However, iptables-save places a
+"   comment in the first line of its output.  Other applications, such as
+"   Fedora's system-config-securitylevel uses the iptables-save/restore
+"   format, but with a different leading comment.  We can use these leading
+"   comments to identify the filetype by placing the following code in the
+"   scripts.vim file in your user runtime directory:
+"   
+"      if getline(1) =~ "^# Generated by iptables-save" ||
+"       \ getline(1) =~ "^# Firewall configuration written by"
+"          setfiletype iptables
+"          set commentstring=#%s
+"          finish
+"      endif
+"
+"   Setting the commentstring on line 4 allows Meikel Brandmeyer's
+"   EnhancedCommentify script (vimscript #23) to work with iptables files.
+"   (Advanced users may want to set the commentstring option in an ftplugin
+"   file or in autocommands defined in .vimrc.)
