+" clipbrd.vim -- Clipboard and other register content editor.
+" Author: Hari Krishna (hari_vim at yahoo dot com)
+" Last Change: 01-Jun-2006 @ 17:57
+" Created: 26-May-2004
+" Requires: Vim-7.0, genutils.vim(2.0)
+" Version: 2.0.1
+" Licence: This program is free software; you can redistribute it and/or
+"          modify it under the terms of the GNU General Public License.
+"          See http://www.gnu.org/copyleft/gpl.txt 
+" Download From:
+"     http://www.vim.org/script.php?script_id=1014
+" Usage:
+"   - Execute the default map (\cb or <Leader>cb) or :ClipBrd command to view
+"     the default register ("*", the clipboard register). You can also specify
+"     the register name as an argument to the :ClipBrd command.
+"   - The register name is remembered (until you change it again by explicitly
+"     specifying it) so that you don't have to specify it everytime you run
+"     :ClipBrd command.
+"   - The "[Clip Board]" buffer is like a regular Vim file buffer, as you can
+"     write (:w, :w!, :wq, :wq!), reload (:e, :e!) and quit (:q, :q!) the
+"     buffer using the built-in Vim commands. Writing without the bang will
+"     make the plugin prompt you for confirmation and where available, you can
+"     click "Cancel" to prevent the buffer from quitting.
+"   - To refresh contents from the register, use :e or :e! command, or just
+"     close and reopen the buffer. To quit without saving, just use the :q!
+"     command.
+"   - <C-G> while in the [Clip Board] buffer shows the register name.
+"   - Even other buffer commands and settings work as expected, e.g., you can
+"     :hide the buffer if you can't decide to save or quit, and the contents
+"     should remain the same when you come back, unless a different register
+"     is explicitly specified while opening the clipboard. Setting 'bufhidden'
+"     to "hide" or 'hidden' also should do the same.
+" Installation:
+"   - Place the file in your plugin directory.
+"   - Also install the latest genutils.vim.
+"   - If you don't like the default map (\cb), change it by placing the
+"     following in your vimrc (change <Your Map> appropriately):
+"       nmap <unique> <silent> <Your Map> <Plug>ClipBrdOpen
+"   - If you want to change the default register from "*" to something else,
+"     put the following in your vimrc:
+"       let g:clipbrdDefaultReg = '+' 
+"     The default register is significant only the first time you invoke the
+"     ClipBrd without specifying any register.  
+"   - You can optionally create a program shortcut with the following as the
+"     command:
+"
+"       gvim +ClipBrd +only
+"
+"     This allows you to use the shortcut to quickly view and edit the
+"     system clipboard. I find it extremely useful. Place the shortcut in a
+"     quick reach (like the windows taskbar) and you will have a powerful
+"     clipboard editor handy all the time.
