+==============================================================================
+1. Intro *NERDTree*
+
+What is this "NERD tree"??
+
+The NERD tree allows you to explore your filesystem and to open files and
+directories. It presents the filesystem to you in the form of a tree which you
+manipulate with the keyboard and/or mouse. It also allows you to perform
+simple filesystem operations.
+
+The following features and functionality are provided by the NERD tree:
+ * Files and directories are displayed in a hierarchical tree structure
+ * Different highlighting is provided for the following types of nodes:
+ * files
+ * directories
+ * sym-links
+ * windows .lnk files
+ * read-only files
+ * executable files
+ * Many (customisable) mappings are provided to manipulate the tree:
+ * Mappings to open/close/explore directory nodes
+ * Mappings to open files in new/existing windows/tabs
+ * Mappings to change the current root of the tree
+ * Mappings to navigate around the tree
+ * ...
+ * Directories and files can be bookmarked.
+ * Most NERD tree navigation can also be done with the mouse
+ * Filtering of tree content (can be toggled at runtime)
+ * custom file filters to prevent e.g. vim backup files being displayed
+ * optional displaying of hidden files (. files)
+ * files can be "turned off" so that only directories are displayed
+ * A textual filesystem menu is provided which allows you to
+ create/delete/move file and directory nodes as well as copy (for
+ supported OSs)
+ * The position and size of the NERD tree window can be customised
+ * The order in which the nodes in the tree are listed can be customised.
+ * A model of your filesystem is created/maintained as you explore it. This
+ has several advantages:
+ * All filesystem information is cached and is only re-read on demand
+ * If you revisit a part of the tree that you left earlier in your
+ session, the directory nodes will be opened/closed as you left them
+ * The script remembers the cursor position and window position in the NERD
+ tree so you can toggle it off (or just close the tree window) and then
+ reopen it (with NERDTreeToggle) the NERD tree window will appear exactly
+ as you left it
+ * You can have a separate NERD tree for each tab, share trees across tabs,
+ or a mix of both.
+ * By default the script overrides the default file browser (netw), so if
+ you :edit a directory a (slighly modified) NERD tree will appear in the
+ current window
+
+==============================================================================
+2. Functionality provided *NERDTreeFunctionality*
+
+------------------------------------------------------------------------------
+2.1. Global Commands *NERDTreeGlobalCommands*
+
+:NERDTree [<start-directory> | <bookmark>] *:NERDTree*
+ Opens a fresh NERD tree. The root of the tree depends on the argument
+ given. There are 3 cases: If no argument is given, the current directory
+ will be used. If a directory is given, that will be used. If a bookmark
+ name is given, the corresponding directory will be used. For example: >
+ :NERDTree /home/marty/vim7/src
+ :NERDTree foo (foo is the name of a bookmark)
+<
+:NERDTreeFromBookmark <bookmark> *:NERDTreeFromBookmark*
+ Opens a fresh NERD tree with the root initialized to the dir for
+ <bookmark>. This only reason to use this command over :NERDTree is for
+ the completion (which is for bookmarks rather than directories).
+
+:NERDTreeToggle [<start-directory> | <bookmark>] *:NERDTreeToggle*
+ If a NERD tree already exists for this tab, it is reopened and rendered
+ again. If no NERD tree exists for this tab then this command acts the
+ same as the |:NERDTree| command.
+
+:NERDTreeMirror *:NERDTreeMirror*
+ Shares an existing NERD tree, from another tab, in the current tab.
+ Changes made to one tree are reflected in both as they are actually the
+ same buffer.
+
+ If only one other NERD tree exists, that tree is automatically mirrored. If
+ more than one exists, the script will ask which tree to mirror.
+
+:NERDTreeClose *:NERDTreeClose*
+ Close the NERD tree in this tab.
+
+------------------------------------------------------------------------------
+2.2. Bookmarks *NERDTreeBookmarks*
+
+Bookmarks in the NERD tree are a way to tag files or directories of interest.
+For example, you could use bookmarks to tag all of your project directories.
+
+------------------------------------------------------------------------------
+2.2.1. The Bookmark Table *NERDTreeBookmarkTable*
+
+If the bookmark table is active (see |NERDTree-B| and
+|'NERDTreeShowBookmarks'|), it will be rendered above the tree. You can double
+click bookmarks or use the |NERDTree-o| mapping to activate them. See also,
+|NERDTree-t| and |NERDTree-T|
+
+------------------------------------------------------------------------------
+2.2.2. Bookmark commands *NERDTreeBookmarkCommands*
+
+Note that the following commands are only available in the NERD tree buffer.
+
+:Bookmark <name>
+ Bookmark the current node as <name>. If there is already a <name>
+ bookmark, it is overwritten. <name> must not contain spaces.
+
+:BookmarkToRoot <bookmark>
+ Make the directory corresponding to <bookmark> the new root. If a treenode
+ corresponding to <bookmark> is already cached somewhere in the tree then
+ the current tree will be used, otherwise a fresh tree will be opened.
+ Note that if <bookmark> points to a file then its parent will be used
+ instead.
+
+:RevealBookmark <bookmark>
+ If the node is cached under the current root then it will be revealed
+ (i.e. directory nodes above it will be opened) and the cursor will be
+ placed on it.
+
+:OpenBookmark <bookmark>
+ <bookmark> must point to a file. The file is opened as though |NERDTree-o|
+ was applied. If the node is cached under the current root then it will be
+ revealed and the cursor will be placed on it.
+
+:ClearBookmarks [<bookmarks>]
+ Remove all the given bookmarks. If no bookmarks are given then remove all
+ bookmarks on the current node.
+
+:ClearAllBookmarks
+ Remove all bookmarks.
+
+:ReadBookmarks
+ Re-read the bookmarks in the |'NERDTreeBookmarksFile'|.
+
+See also |:NERDTree| and |:NERDTreeFromBookmark|.
+
+------------------------------------------------------------------------------
+2.2.3. Invalid Bookmarks *NERDTreeInvalidBookmarks*
+
+If invalid bookmarks are detected, the script will issue an error message and
+the invalid bookmarks will become unavailable for use.
+
+These bookmarks will still be stored in the bookmarks file (see
+|'NERDTreeBookmarksFile'|), down the bottom. There will always be a blank line
+after the valid bookmarks but before the invalid ones.
+
+Each line in the bookmarks file represents one bookmark. The proper format is:
+<bookmark name><space><full path to the bookmark location>
+
+After you have corrected any invalid bookmarks, either restart vim, or go
+:ReadBookmarks from the NERD tree window.

+2.3. The filesystem menu *NERDTreeFilesysMenu*
+
+The purpose of the filesystem menu is to allow you to perform basic filesystem
+operations quickly from the NERD tree rather than the console.
+
+The filesystem menu can be accessed with 'm' mapping and has four supported
+operations: >
+ 1. Adding nodes.
+ 2. Move nodes.
+ 3. Deleting nodes.
+ 3. Copying nodes.
+<
+1. Adding nodes:
+To add a node move the cursor onto (or anywhere inside) the directory you wish
+to create the new node inside. Select the 'add node' option from the
+filesystem menu and type a filename. If the filename you type ends with a '/'
+character then a directory will be created. Once the operation is completed,
+the cursor is placed on the new node.
+
+2. Move nodes:
+To move/rename a node, put the cursor on it and select the 'move' option from
+the filesystem menu. Enter the new location for the node and it will be
+moved. If the old file is open in a buffer, you will be asked if you wish to
+delete that buffer. Once the operation is complete the cursor will be placed
+on the renamed node.
+
+3. Deleting nodes:
+To delete a node put the cursor on it and select the 'delete' option from the
+filesystem menu. After confirmation the node will be deleted. If a file is
+deleted but still exists as a buffer you will be given the option to delete
+that buffer.
+
+4. Copying nodes:
+To copy a node put the cursor on it and select the 'copy' option from the
+filesystem menu. Enter the new location and you're done. Note: copying is
+currently only supported for *nix operating systems. If someone knows a
+one line copying command for windows that doesnt require user confirmation
+then id be grateful if you'd email me.
+
+==============================================================================
+3. Customisation *NERDTreeOptions*
+
+
+------------------------------------------------------------------------------
+3.1. Customisation summary *NERDTreeOptionSummary*
+
+The script provides the following options that can customise the behaviour the
+NERD tree. These options should be set in your vimrc.
+
+|'loaded_nerd_tree'| Turns off the script.
+
+|'NERDChristmasTree'| Tells the NERD tree to make itself colourful
+ and pretty.
+
+|'NERDTreeAutoCenter'| Controls whether the NERD tree window centers
+ when the cursor moves within a specified
+ distance to the top/bottom of the window.
+|'NERDTreeAutoCenterThreshold'| Controls the sensitivity of autocentering.
+
+|'NERDTreeCaseSensitiveSort'| Tells the NERD tree whether to be case
+ sensitive or not when sorting nodes.
+
+|'NERDTreeChDirMode'| Tells the NERD tree if/when it should change
+ vim's current working directory.
+
+|'NERDTreeHighlightCursorline'| Tell the NERD tree whether to highlight the
+ current cursor line.
+
+|'NERDTreeHijackNetrw'| Tell the NERD tree whether to replace the netrw
+ autocommands for exploring local directories.
+
+|'NERDTreeIgnore'| Tells the NERD tree which files to ignore.
+
+|'NERDTreeBookmarksFile'| Where the bookmarks are stored.
+
+|'NERDTreeMouseMode'| Tells the NERD tree how to handle mouse
+ clicks.
+
+|'NERDTreeQuitOnOpen'| Closes the tree window after opening a file.
+
+|'NERDTreeShowBookmarks'| Tells the NERD tree whether to display the
+ bookmarks table on startup.
+
+|'NERDTreeShowFiles'| Tells the NERD tree whether to display files
+ in the tree on startup.
+
+|'NERDTreeShowHidden'| Tells the NERD tree whether to display hidden
+ files on startup.
+
+|'NERDTreeShowLineNumbers'| Tells the NERD tree whether to display line
+ numbers in the tree window.
+
+|'NERDTreeSortOrder'| Tell the NERD tree how to sort the nodes in
+ the tree.
+
+|'NERDTreeStatusline'| Set a statusline for NERD tree windows.
+
+|'NERDTreeWinPos'| Tells the script where to put the NERD tree
+ window.
+
+|'NERDTreeWinSize'| Sets the window size when the NERD tree is
+ opened.
+
+------------------------------------------------------------------------------
+3.2. Customisation details *NERDTreeOptionDetails*
+
+To enable any of the below options you should put the given line in your
+~/.vimrc
+
+ *'loaded_nerd_tree'*
+If this plugin is making you feel homicidal, it may be a good idea to turn it
+off with this line in your vimrc: >
+ let loaded_nerd_tree=1
+<
+------------------------------------------------------------------------------
+ *'NERDChristmasTree'*
+Values: 0 or 1.
+Default: 1.
+
+If this option is set to 1 then some extra syntax highlighting elements are
+added to the nerd tree to make it more colourful.
+
+Set it to 0 for a more vanilla looking tree.
+
+------------------------------------------------------------------------------
+ *'NERDTreeAutoCenter'*
+Values: 0 or 1.
+Default: 1
+
+If set to 1, the NERD tree window will center around the cursor if it moves to
+within |'NERDTreeAutoCenterThreshold'| lines of the top/bottom of the window.
+
+This is ONLY done in response to tree navigation mappings,
+i.e. |NERDTree-J| |NERDTree-K| |NERDTree-C-J| |NERDTree-C-K| |NERDTree-p|
+|NERDTree-P|
+
+The centering is done with a |zz| operation.
+
+------------------------------------------------------------------------------
+ *'NERDTreeAutoCenterThreshold'*
+Values: Any natural number.
+Default: 3
+
+This option controls the "sensitivity" of the NERD tree auto centering. See
+|'NERDTreeAutoCenter'| for details.
+
+------------------------------------------------------------------------------
+ *'NERDTreeCaseSensitiveSort'*
+Values: 0 or 1.
+Default: 0.
+
+By default the NERD tree does not sort nodes case sensitively, i.e. nodes
+could appear like this: >
+ bar.c
+ Baz.c
+ blarg.c
+ boner.c
+ Foo.c
+<
+But, if you set this option to 1 then the case of the nodes will be taken into
+account. The above nodes would then be sorted like this: >
+ Baz.c
+ Foo.c
+ bar.c
+ blarg.c
+ boner.c
+<
+------------------------------------------------------------------------------
+ *'NERDTreeChDirMode'*
+
+Values: 0, 1 or 2.
+Default: 0.
+
+Use this option to tell the script when (if at all) to change the current
+working directory (CWD) for vim.
+
+If it is set to 0 then the CWD is never changed by the NERD tree.
+
+If set to 1 then the CWD is changed when the NERD tree is first loaded to the
+directory it is initialized in. For example, if you start the NERD tree with >
+ :NERDTree /home/marty/foobar
+<
+then the CWD will be changed to /home/marty/foobar and will not be changed
+again unless you init another NERD tree with a similar command.
+
+If the option is set to 2 then it behaves the same as if set to 1 except that
+the CWD is changed whenever the tree root is changed. For example, if the CWD
+is /home/marty/foobar and you make the node for /home/marty/foobar/baz the new
+root then the CWD will become /home/marty/foobar/baz.
+
+------------------------------------------------------------------------------
+ *'NERDTreeHighlightCursorline'*
+Values: 0 or 1.
+Default: 1.
+
+If set to 1, the current cursor line in the NERD tree buffer will be
+highlighted. This is done using the |'cursorline'| option.
+
+------------------------------------------------------------------------------
+ *'NERDTreeHijackNetrw'*
+Values: 0 or 1.
+Default: 1.
+
+If set to 1, doing a >
+ :edit <some directory>
+<
+will open up a "secondary" NERD tree instead of a netrw in the target window.
+
+Secondary NERD trees behaves slighly different from a regular trees in the
+following respects:
+ 1. 'o' will open the selected file in the same window as the tree,
+ replacing it.
+ 2. you can have as many secondary tree as you want in the same tab.
+
+------------------------------------------------------------------------------
+ *'NERDTreeIgnore'*
+Values: a list of regular expressions.
+Default: ['\~$'].
+
+This option is used to specify which files the NERD tree should ignore. It
+must be a list of regular expressions. When the NERD tree is rendered, any
+files/dirs that match any of the regex's in 'NERDTreeIgnore' wont be
+displayed.
+
+For example if you put the following line in your vimrc: >
+ let NERDTreeIgnore=['\.vim$', '\~$']
+<
+then all files ending in .vim or ~ will be ignored.
+
+Note: to tell the NERD tree not to ignore any files you must use the following
+line: >
+ let NERDTreeIgnore=[]
+<
+
+The file filters can be turned on and off dynamically with the |NERDTree-f|
+mapping.
+
+------------------------------------------------------------------------------
+ *'NERDTreeBookmarksFile'*
+Values: a path
+Default: $HOME/.NERDTreeBookmarks
+
+This is where bookmarks are saved. See |NERDTreeBookmarkCommands|.
+
+------------------------------------------------------------------------------
+ *'NERDTreeMouseMode'*
+Values: 1, 2 or 3.
+Default: 1.
+
+If set to 1 then a double click on a node is required to open it.
+If set to 2 then a single click will open directory nodes, while a double
+click will still be required for file nodes.
+If set to 3 then a single click will open any node.
+
+Note: a double click anywhere on a line that a tree node is on will
+activate it, but all single-click activations must be done on name of the node
+itself. For example, if you have the following node: >
+ | | |-application.rb
+<
+then (to single click activate it) you must click somewhere in
+'application.rb'.
+
+------------------------------------------------------------------------------
+ *'NERDTreeQuitOnOpen'*
+
+Values: 0 or 1.
+Default: 0
+
+If set to 1, the NERD tree window will close after opening a file with the
+|NERDTree-o| or |NERDTree-i| mappings.
+
+------------------------------------------------------------------------------
+ *'NERDTreeShowBookmarks'*
+Values: 0 or 1.
+Default: 0.
+
+If this option is set to 1 then the bookmarks table will be displayed.
+
+This option can be toggled dynamically, per tree, with the |NERDTree-B|
+mapping.
+
+------------------------------------------------------------------------------
+ *'NERDTreeShowFiles'*
+Values: 0 or 1.
+Default: 1.
+
+If this option is set to 1 then files are displayed in the NERD tree. If it is
+set to 0 then only directories are displayed.
+
+This option can be toggled dynamically, per tree, with the |NERDTree-F|
+mapping and is useful for drastically shrinking the tree when you are
+navigating to a different part of the tree.
+
+------------------------------------------------------------------------------
+ *'NERDTreeShowHidden'*
+Values: 0 or 1.
+Default: 0.
+
+This option tells vim whether to display hidden files by default. This option
+can be dynamically toggled, per tree, with the |NERDTree-I| mapping. Use one
+of the follow lines to set this option: >
+ let NERDTreeShowHidden=0
+ let NERDTreeShowHidden=1
+<
+
+------------------------------------------------------------------------------
+ *'NERDTreeShowLineNumbers'*
+Values: 0 or 1.
+Default: 0.
+
+This option tells vim whether to display line numbers for the NERD tree
+window. Use one of the follow lines to set this option: >
+ let NERDTreeShowLineNumbers=0
+ let NERDTreeShowLineNumbers=1
+<
+
+------------------------------------------------------------------------------
+ *'NERDTreeSortOrder'*
+Values: a list of regular expressions.
+Default: ['\/$', '*', '\.swp$', '\.bak$', '\~$']
+
+This option is set to a list of regular expressions which are used to
+specify the order of nodes under their parent.
+
+For example, if the option is set to: >
+ ['\.vim$', '\.c$', '\.h$', '*', 'foobar']
+<
+then all .vim files will be placed at the top, followed by all .c files then
+all .h files. All files containing the string 'foobar' will be placed at the
+end. The star is a special flag: it tells the script that every node that
+doesnt match any of the other regexps should be placed here.
+
+If no star is present in 'NERDTreeSortOrder' then one is automatically
+appended to the array.
+
+The regex '\/$' should be used to match directory nodes.
+
+After this sorting is done, the files in each group are sorted alphabetically.
+
+Other examples: >
+ (1) ['*', '\/$']
+ (2) []
+ (3) ['\/$', '\.rb$', '\.php$', '*', '\.swp$', '\.bak$', '\~$']
+<
+1. Directories will appear last, everything else will appear above.
+2. Everything will simply appear in alphabetical order.
+3. Dirs will appear first, then ruby and php. Swap files, bak files and vim
+ backup files will appear last with everything else preceding them.
+
+------------------------------------------------------------------------------
+ *'NERDTreeStatusline'*
+Values: Any valid statusline setting.
+Default: %{b:NERDTreeRoot.path.strForOS(0)}
+
+Tells the script what to use as the |'statusline'| setting for NERD tree
+windows.
+
+Note that the statusline is set using |:let-&| not |:set| so escaping spaces
+isn't necessary.
+
+Setting this option to -1 will will deactivate it so that your global
+statusline setting is used instead.
+
+------------------------------------------------------------------------------
+ *'NERDTreeWinPos'*
+Values: "left" or "right"
+Default: "left".
+
+This option is used to determine where NERD tree window is placed on the
+screen.
+
+This option makes it possible to use two different explorer plugins
+simultaneously. For example, you could have the taglist plugin on the left of
+the window and the NERD tree on the right.
+
+------------------------------------------------------------------------------
+ *'NERDTreeWinSize'*
+Values: a positive integer.
+Default: 31.
+
+This option is used to change the size of the NERD tree when it is loaded.
+
+==============================================================================
+4. Hacking the NERD tree *NERDTreeHacking*
+
+Public functions ~
+
+The script provides 2 public functions for your hacking pleasure. Their
+signatures are: >
+ function! NERDTreeGetCurrentNode()
+ function! NERDTreeGetCurrentPath()
+<
+The first returns the node object that the cursor is currently on, while the
+second returns the corresponding path object.
+
+This is probably a good time to mention that the script implements prototype
+style OO. To see the functions that each class provides you can read look at
+the code.
+
+Use the node objects to manipulate the structure of the tree. Use the path
+objects to access the files/directories the tree nodes represent.
+
+The NERD tree filetype ~
+
+NERD tree buffers have a filetype of "nerdtree". You can use this to hack the
+NERD tree via autocommands (on |FileType|) or via an ftplugin.
+
+For example, putting this code in ~/.vim/ftplugin/nerdtree.vim would override
+the o mapping, making it open the selected node in a new gvim instance. >
+
+ nnoremap <silent> <buffer> o :call <sid>openInNewVimInstance()<cr>
+ function! s:openInNewVimInstance()
+ let p = NERDTreeGetCurrentPath()
+ if p != {}
+ silent exec "!gvim " . p.strForOS(1) . "&"
+ endif
+ endfunction
+<
+This way you can add new mappings or :commands or override any existing
+mapping.

+ thanks to jamessan
+ - fix a bunch of small bugs with secondary trees
+
+ More insane refactoring.
