" Name Of File: bufexplorer.vim
" Description: Buffer Explorer Vim Plugin
" Maintainer: Jeff Lanzarotta (delux256-vim at yahoo dot com)
" Last Changed: Tuesday, 04 Dec 2012
" Version: See g:bufexplorer_version for version number.
" Usage: This file should reside in the plugin directory and be
" automatically sourced.
"
" You may use the default keymappings of
"
" <Leader>be - Opens BufExplorer
" <Leader>bs - Opens horizontally split window BufExplorer
" <Leader>bv - Opens vertically split window BufExplorer
"
" Or you can override the defaults and define your own mapping
" in your vimrc file, for example:
"
" noremap <silent> <F11> :BufExplorer<CR>
" noremap <silent> <m-F11> :BufExplorerHorizontalSplit<CR>
" noremap <silent> <c-F11> :BufExplorerVerticalSplit<CR>
"
" Or you can use
"
" ":BufExplorer" - Opens BufExplorer
" ":BufExplorerHorizontalSplit" - Opens horizontally window BufExplorer
" ":BufExplorerVerticalSplit" - Opens vertically split window BufExplorer
"
" For more help see supplied documentation.
" History: See supplied documentation.
" Issues: 'D' and 'd' remove the buffer from the list but the list is not
" displayed correctly.
" - Add ability to open a buffer in a new split when \be is used.
