+" Name Of File: minibufexpl.vim
+"  Description: Mini Buffer Explorer Vim Plugin
+"   Maintainer: Bindu Wavell <bindu@wavell.net>
+"          URL: http://vim.sourceforge.net/scripts/script.php?script_id=159
+"  Last Change: Sunday, June 21, 2004
+"      Version: 6.3.2
+"               Derived from Jeff Lanzarotta's bufexplorer.vim version 6.0.7
+"               Jeff can be reached at (jefflanzarotta@yahoo.com) and the
+"               original plugin can be found at:
+"               http://lanzarotta.tripod.com/vim/plugin/6/bufexplorer.vim.zip
+"
+"        Usage: Normally, this file should reside in the plugins
+"               directory and be automatically sourced. If not, you must
+"               manually source this file using ':source minibufexplorer.vim'.
+"
+"               You may use the default keymappings of
+"
+"                 <Leader>mbe - Opens MiniBufExplorer
+"
+"               or you may want to add something like the following
+"               key mapping to your _vimrc/.vimrc file.
+"
+"                 map <Leader>b :MiniBufExplorer<cr>
+"
+"               However, in most cases you won't need any key-bindings at all.
+"
+"               <Leader> is usually backslash so type "\mbe" (quickly) to open 
+"               the -MiniBufExplorer- window.
+"
+"               Other keymappings include: <Leader>mbc to close the Explorer
+"               window,  <Leader>mbu to force the Explorer to Update and
+"               <Leader>mbt to toggle the Explorer window; it will open if
+"               closed or close if open. Each of these key bindings can be
+"               overridden (see the notes on <Leader>mbe above.)
+" 
+"               You can map these additional commands as follows:
+"
+"                 map <Leader>c :CMiniBufExplorer<cr>
+"                 map <Leader>u :UMiniBufExplorer<cr>
+"                 map <Leader>t :TMiniBufExplorer<cr>
+"
+"               NOTE: you can change the key binding used in these mappings
+"                     so that they fit with your configuration of vim.
+"
+"               You can also call each of these features by typing the
+"               following in command mode:
+"
+"                 :MiniBufExplorer    " Open and/or goto Explorer
+"                 :CMiniBufExplorer   " Close the Explorer if it's open
+"                 :UMiniBufExplorer   " Update Explorer without navigating
+"                 :TMiniBufExplorer   " Toggle the Explorer window open and 
+"                                       closed.
+"
+"               To control where the new split window goes relative to the 
+"               current window, use the setting:
+"
+"                 let g:miniBufExplSplitBelow=0  " Put new window above
+"                                                " current or on the
+"                                                " left for vertical split
+"                 let g:miniBufExplSplitBelow=1  " Put new window below
+"                                                " current or on the
+"                                                " right for vertical split
+"
+"               The default for this is read from the &splitbelow VIM option.
+"
+"               By default we are now (as of 6.0.2) forcing the -MiniBufExplorer-
+"               window to open up at the edge of the screen. You can turn this 
+"               off by setting the following variable in your .vimrc:
+"
+"                 let g:miniBufExplSplitToEdge = 0
+"
+"               If you would like a vertical explorer you can assign the column
+"               width (in characters) you want for your explorer window with the
+"               following .vimrc variable (this was introduced in 6.3.0):
+"
+"                 let g:miniBufExplVSplit = 20   " column width in chars
+"
+"               IN HORIZONTAL MODE:
+"               It is now (as of 6.1.1) possible to set a maximum height for
+"               the -MiniBufExplorer- window. You can set the max height by
+"               letting the following variable in your .vimrc:
+"
+"                 let g:miniBufExplMaxSize = <max lines: defualt 0>
+"               
+"               setting this to 0 will mean the window gets as big as
+"               needed to fit all your buffers. 
+"
+"               NOTE: This was g:miniBufExplMaxHeight before 6.3.0; the old
+"               setting is backwards compatible if you don't use MaxSize.
+"
+"               As of 6.2.2 it is possible to set a minimum height for the 
+"               -MiniBufExplorer- window. You can set the min height by
+"               letting the following variable in your .vimrc:
+"
+"                 let g:miniBufExplMinSize = <min height: default 1>
+"
+"               NOTE: This was g:miniBufExplMinHeight before 6.3.0; the old
+"               setting is backwards compatible if you don't use MinSize.
+"
+"               IN VERTICAL MODE: (as of 6.3.0)
+"               By default the vertical explorer has a fixed width. If you put:
+"
+"                 let g:miniBufExplMaxSize = <max width: default 0> 
+"
+"               into your .vimrc then MBE will attempt to set the width of the
+"               MBE window to be as wide as your widest tab. The width will not
+"               exceed MaxSize even if you have wider tabs. 
+"
+"               Accepting the default value of 0 for this will give you a fixed
+"               width MBE window.
+"
+"               You can specify a MinSize for the vertical explorer window by
+"               putting the following in your .vimrc:
+"
+"                 let g:miniBufExplMinSize = <min width: default 1>
+"
+"               This will have no effect unless you also specivy MaxSize.
+"
+"               By default we are now (as of 6.0.1) turning on the MoreThanOne
+"               option. This stops the -MiniBufExplorer- from opening 
+"               automatically until more than one eligible buffer is available.
+"               You can turn this feature off by setting the following variable
+"               in your .vimrc:
+"                 
+"                 let g:miniBufExplorerMoreThanOne=1
+"
+"               (The following enhancement is as of 6.2.2)
+"               Setting this to 0 will cause the MBE window to be loaded even
+"               if no buffers are available. Setting it to 1 causes the MBE
+"               window to be loaded as soon as an eligible buffer is read. You
+"               can also set it to larger numbers. So if you set it to 4 for
+"               example the MBE window wouldn't auto-open until 4 eligibles
+"               buffers had been loaded. This is nice for folks that don't 
+"               want an MBE window unless they are editing more than two or
+"               three buffers.
+"
+"               To enable the optional mapping of Control + Vim Direction Keys 
+"               [hjkl] to window movement commands, you can put the following into 
+"               your .vimrc:
+"
+"                 let g:miniBufExplMapWindowNavVim = 1
+"
+"               To enable the optional mapping of Control + Arrow Keys to window 
+"               movement commands, you can put the following into your .vimrc:
+"
+"                 let g:miniBufExplMapWindowNavArrows = 1
+"
+"               To enable the optional mapping of <C-TAB> and <C-S-TAB> to a 
+"               function that will bring up the next or previous buffer in the
+"               current window, you can put the following into your .vimrc:
+"
+"                 let g:miniBufExplMapCTabSwitchBufs = 1
+"
+"               To enable the optional mapping of <C-TAB> and <C-S-TAB> to mappings
+"               that will move to the next and previous (respectively) window, you
+"               can put the following into your .vimrc:
+"
+"                 let g:miniBufExplMapCTabSwitchWindows = 1
+"
+"
+"               NOTE: If you set the ...TabSwitchBufs AND ...TabSwitchWindows, 
+"                     ...TabSwitchBufs will be enabled and ...TabSwitchWindows 
+"                     will not.
+"               
+"               As of MBE 6.3.0, you can put the following into your .vimrc:
+"               
+"                 let g:miniBufExplUseSingleClick = 1
+"
+"               If you would like to single click on tabs rather than double
+"               clicking on them to goto the selected buffer. 
+"
+"               NOTE: If you use the single click option in taglist.vim you may 
+"                     need to get an updated version that includes a patch I 
+"                     provided to allow both explorers to provide single click 
+"                     buffer selection.
+"
+"               It is possible to customize the the highlighting for the tabs in 
+"               the MBE by configuring the following highlighting groups:
+"
+"                 MBENormal         - for buffers that have NOT CHANGED and
+"                                     are NOT VISIBLE.
+"                 MBEChanged        - for buffers that HAVE CHANGED and are
+"                                     NOT VISIBLE
+"                 MBEVisibleNormal  - buffers that have NOT CHANGED and are
+"                                     VISIBLE
+"                 MBEVisibleChanged - buffers that have CHANGED and are VISIBLE
+"
+"               You can either link to an existing highlighting group by
+"               adding a command like:
+"
+"                 hi link MBEVisibleChanged Error
+"
+"               to your .vimrc or you can specify exact foreground and background
+"               colors using the following syntax:
+"
+"                 hi MBEChanged guibg=darkblue ctermbg=darkblue termbg=white
+"
+"               NOTE: If you set a colorscheme in your .vimrc you should do it
+"                     BEFORE updating the MBE highlighting groups.
+"
+"               If you use other explorers like TagList you can (As of 6.2.8) put:
+"
+"                 let g:miniBufExplModSelTarget = 1
+" 
+"               into your .vimrc in order to force MBE to try to place selected 
+"               buffers into a window that does not have a nonmodifiable buffer.
+"               The upshot of this should be that if you go into MBE and select
+"               a buffer, the buffer should not show up in a window that is 
+"               hosting an explorer.
+"
+"               There is a VIM bug that can cause buffers to show up without 
+"               their highlighting. The following setting will cause MBE to
+"               try and turn highlighting back on (introduced in 6.3.1):
+"
+"                 let g:miniBufExplForceSyntaxEnable = 1
+"
+"               MBE has had a basic debugging capability for quite some time.
+"               However, it has not been very friendly in the past. As of 6.0.8, 
+"               you can put one of each of the following into your .vimrc:
+"
+"                 let g:miniBufExplorerDebugLevel = 0  " MBE serious errors output
+"                 let g:miniBufExplorerDebugLevel = 4  " MBE all errors output
+"                 let g:miniBufExplorerDebugLevel = 10 " MBE reports everything
+"
+"               You can also set a DebugMode to cause output to be target as
+"               follows (default is mode 3):
+"
+"                 let g:miniBufExplorerDebugMode  = 0  " Errors will show up in 
+"                                                      " a vim window
+"                 let g:miniBufExplorerDebugMode  = 1  " Uses VIM's echo function
+"                                                      " to display on the screen
+"                 let g:miniBufExplorerDebugMode  = 2  " Writes to a file
+"                                                      " MiniBufExplorer.DBG
+"                 let g:miniBufExplorerDebugMode  = 3  " Store output in global:
+"                                                 " g:miniBufExplorerDebugOutput
+"
+"               Or if you are able to start VIM, you might just perform these
+"               at a command prompt right before you do the operation that is
+"               failing.
+"
+"      History: Moved to end of file
+"      
+" Known Issues: When debugging is turned on and set to output to a window, there
+"               are some cases where the window is opened more than once, there
+"               are other cases where an old debug window can be lost.
+" 
+"               Several MBE commands can break the window history so <C-W>[pnw]
+"               might not take you to the expected window.
+"
+"         Todo: Add the ability to specify a regexp for eligible buffers
+"               allowing the ability to filter out certain buffers that 
+"               you don't want to control from MBE

+"               6.3.1 o Include folds in source so that it's easier to 
+"                       navigate.
+"                     o Added g:miniBufExplForceSyntaxEnable setting for folks
+"                       that want a :syntax enable to be called when we enter 
+"                       buffers. This can resolve issues caused by a vim bug
+"                       where buffers show up without highlighting when another 
+"                       buffer has been closed, quit, wiped or deleted.
+"               6.3.0 o Added an option to allow single click (rather than
+"                       the default double click) to select buffers in the
+"                       MBE window. This feature was requested by AW Law
+"                       and was inspired by taglist.vim. Note that you will 
+"                       need the latest version of taglist.vim if you want to 
+"                       use MBE and taglist both with singleclick turned on.
+"                       Also thanks to AW Law for pointing out that you can
+"                       make an Explorer not be listed in a standard :ls.
+"                     o Added the ability to have your tabs show up in a
+"                       vertical window rather than the standard horizontal
+"                       one. Just let g:miniBufExplVSplit = <width> in your
+"                       .vimrc and your will get this functionality.
+"                     o If you use the vertical explorer and you want it to
+"                       autosize then let g:miniBufExplMaxSize = <max width>
+"                       in your .vimrc. You may use the MinSize letting in
+"                       addition to the MaxLetting if you don't want a super
+"                       thin window.
+"                     o g:miniBufExplMaxHeight was renamed g:miniBufExplMaxSize
+"                       g:miniBufExplMinHeight was renamed g:miniBufExplMinSize
+"                       the old settings are backwards compatible if you don't
+"                       use the new settings, but they are depreciated.
+"               6.2.8 o Add an option to stop MBE from targeting non-modifiable
+"                       buffers when switching buffers. Thanks to AW Law for
+"                       the inspiration for this. This may not work if a user
+"                       has lots of explorer/help windows open.
+"               6.2.7 o Very minor bug fix for people who want to set
+"                       loaded_minibufexplorer in their .vimrc in order to
+"                       stop MBE from loading. 99.99% of users do not need
+"                       this update.
+"               6.2.6 o Moved history to end of source file
+"                     o Updated highlighting documentation
+"                     o Created global commands MBEbn and MBEbp that can be 
+"                       used in mappings if folks want to cycle buffers while 
+"                       skipping non-eligible buffers.
+"               6.2.5 o Added <Leader>mbt key mapping which will toggle
+"                       the MBE window. I map this to F3 in my .vimrc
+"                       with "map <F3> :TMiniBufExplorer<CR>" which 
+"                       means I can easily close the MBE window when I'm 
+"                       not using it and get it back when I want it.
+"                     o Changed default debug mode to 3 (write to global
+"                       g:miniBufExplorerDebugOutput)
+"                     o Made a pass through the documentation to clarify 
+"                       serveral issues and provide more complete docs
+"                       for mappings and commands.
+"               6.2.4 o Because of the autocommand switch (see 6.2.0) it 
+"                       was possible to remove the restriction on the
+"                       :set hidden option. It is now possible to use
+"                       this option with MBE.
+"               6.2.3 o Added miniBufExplTabWrap option. It is turned 
+"                       off by default. When turned on spaces are added
+"                       between tabs and gq} is issued to perform line
+"                       formatting. This won't work very well if filenames
+"                       contain spaces. It would be pretty easy to write
+"                       my own formatter, but I'm too lazy, so if someone
+"                       really needs that feature I'll add it :)
+"               6.2.2 o Changed the way the g:miniBufExplorerMoreThanOne
+"                       global is handled. You can set this to the number
+"                       of eligible buffers you want to be loaded before
+"                       the MBE window is loaded. Setting it to 0 causes
+"                       the MBE window to be opened even if there are no
+"                       buffers. Setting it to 4 causes the window to stay
+"                       closed until the 4th eligible buffer is loaded.
+"                     o Added a MinHeight option. This is nice if you want
+"                       the MBE window to always take the same amount of
+"                       space. For example set MaxSize and MinSize to 2
+"                       and set MoreThanOne to 0 and you will always have
+"                       a 2 row (plus the ruler :) MBE window.
+"                       NOTE: in 6.3.0 we started using MinSize instead of
+"                       Minheight. This will still work if MinSize is not
+"                       specified, but it is depreciated. Use MinSize instead.
+"                     o I now setlocal foldcomun=0 and nonumber in the MBE 
+"                       window. This is for those of you that like to have
+"                       these options turned on locally. I'm assuming noone
+"                       outthere wants foldcolumns and line numbers in the
+"                       MBE window? :)
+"                     o Fixed a bug where an empty MBE window was taking half
+"                       of the screen (partly why the MinHeight option was 
+"                       added.)
+"               6.2.1 o If MBE is the only window (because of :bd for example)
+"                       and there are still eligible buffers then one of them
+"                       will be displayed.
+"                     o The <Leader>mbe mapping now highlights the buffer from
+"                       the current window.
+"                     o The delete ('d') binding in the MBE window now restors
+"                       the cursor position, which can help if you want to 
+"                       delete several buffers in a row that are not at the
+"                       beginning of the buffer list.
+"                     o Added a new key binding ('p') in the MBE window to 
+"                       switch to the previous window (last edit window)
+"               6.2.0 o Major overhaul of autocommand and list updating code,
+"                       we now have much better handling of :bd (which is the 
+"                       most requested feature.) As well as resolving other
+"                       issues where the buffer list would not be updated
+"                       automatically. The old version tried to trap specific
+"                       events, this one just updates frequently, but it keeps
+"                       track and only changes the screen if there has been
+"                       a change.
+"                     o Added g:miniBufExplMaxHeight variable so you can keep
+"                       the -MiniBufExplorer- window small when you have lots
+"                       of buffers (or buffers with long names :)
+"                       NOTE: in 6.3.0 we started using MaxSize instead of
+"                       MaxHeight. This will still work if MaxSize is not
+"                       specified, but it is depreciated. Use MaxSize instead.
+"                     o Improvement to internal syntax highlighting code
+"                       I renamed the syntax group names. Anyone who has 
+"                       figured out how to use them already shouldn't have
+"                       any trouble with the new Nameing :)
+"                     o Added debug mode 3 which writes to a global variable
+"                       this is fast and doesn't mess with the buffer/window
+"                       lists.
+"               6.1.0 o <Leader>mbc was failing because I was calling one of
+"                       my own functions with the wrong number of args. :(
+"                       Thanks to Gerry Patterson for finding this!
+"                       This code is very stable (although it has some
+"                       idiocyncracies.)
+"               6.0.9 o Double clicking tabs was overwriting the cliboard 
+"                       register on MS Windows.  Thanks to Shoeb Bhinderwala 
+"                       for reporting this issue.
+"               6.0.8 o Apparently some VIM builds are having a hard time with
+"                       line continuation in scripts so the few that were here
+"                       have been removed.
+"                     o Generalized FindExplorer and FindCreateExplorer so
+"                       that they can be used for the debug window. Renaming
+"                       to FindWindow and FindCreateWindow.
+"                     o Updated debugging code so that debug output is put into
+"                       a buffer which can then be written to disk or emailed
+"                       to me when someone is having a major issue. Can also
+"                       write directly to a file (VERY SLOWLY) on UNIX or Win32
+"                       (not 95 or 98 at the moment) or use VIM's echo function 
+"                       to display the output to the screen.
+"                     o Several people have had issues when the hidden option 
+"                       is turned on. So I have put in several checks to make
+"                       sure folks know this if they try to use MBE with this
+"                       option set.
+"               6.0.7 o Handling BufDelete autocmd so that the UI updates 
+"                       properly when using :bd (rather than going through 
+"                       the MBE UI.)
+"                     o The AutoUpdate code will now close the MBE window when 
+"                       there is a single eligible buffer available.
+"                       This has the usefull side effect of stopping the MBE
+"                       window from blocking the VIM session open when you close 
+"                       the last buffer.
+"                     o Added functions, commands and maps to close & update
+"                       the MBE window (<leader>mbc and <leader>mbu.)
+"                     o Made MBE open/close state be sticky if set through
+"                       StartExplorer(1) or StopExplorer(1), which are 
+"                       called from the standard mappings. So if you close
+"                       the mbe window with \mbc it won't be automatically 
+"                       opened again unless you do a \mbe (or restart VIM).
+"                     o Removed spaces between "tabs" (even more mini :)
+"                     o Simplified MBE tab processing 
+"               6.0.6 o Fixed register overwrite bug found by Sébastien Pierre
+"               6.0.5 o Fixed an issue with window sizing when we run out of 
+"                       buffers.  
+"                     o Fixed some weird commenting bugs.  
+"                     o Added more optional fancy window/buffer navigation:
+"                     o You can turn on the capability to use control and the 
+"                       arrow keys to move between windows.
+"                     o You can turn on the ability to use <C-TAB> and 
+"                       <C-S-TAB> to open the next and previous (respectively) 
+"                       buffer in the current window.
+"                     o You can turn on the ability to use <C-TAB> and 
+"                       <C-S-TAB> to switch windows (forward and backwards 
+"                       respectively.)
+"               6.0.4 o Added optional fancy window navigation: 
+"                     o Holding down control and pressing a vim direction 
+"                       [hjkl] will switch windows in the indicated direction.
+"               6.0.3 o Changed buffer name to -MiniBufExplorer- to resolve
+"                       Issue in filename pattern matching on Windows.
+"               6.0.2 o 2 Changes requested by Suresh Govindachar:
+"                     o Added SplitToEdge option and set it on by default
+"                     o Added tab and shift-tab mappings in [MBE] window
+"               6.0.1 o Added MoreThanOne option and set it on by default
+"                       MiniBufExplorer will not automatically open until
+"                       more than one eligible buffers are opened. This
+"                       reduces cluter when you are only working on a
+"                       single file. 
+"                       NOTE: See change log for 6.2.2 for more details about 
+"                             this feature
+"               6.0.0 o Initial Release on November 20, 2001
