    2. Vimball Introduction						*vimball-intro*

    	Vimball is intended to make life simpler for users of plugins.  All
    	a user needs to do with a vimball is:
    		vim someplugin.vba
    		:so %
    		:q
     	and the plugin and all its components will be installed into their
    	appropriate directories.  Note that one doesn't need to be in any
    	particular directory when one does this.  Plus, any help for the
    	plugin will also be automatically installed.

    	If a user has decided to use the AsNeeded plugin, vimball is smart
    	enough to put scripts nominally intended for .vim/plugin/ into
    	.vim/AsNeeded/ instead.

    	Removing a plugin that was installed with vimball is really easy:
    		vim
    		:RmVimball someplugin
     	This operation is not at all easy for zips and tarballs, for example.

    	Vimball examines the user's |'runtimepath'| to determine where to put
    	the scripts.  The first directory mentioned on the runtimepath is
    	usually used if possible.  Use
    		:echo &rtp
     	to see that directory.

    ==============================================================================

    3. Vimball Manual					*vimball-manual*

    							*:MkVimball*
    		:[range]MkVimball[!] filename [path]

    	The range is composed of lines holding paths to files to be included
    	in your new vimball, omitting the portion of the paths that is
    	normally specified by the runtimepath (|'rtp'|).  As an example:
    		plugin/something.vim
    		doc/something.txt
     	using
    		:[range]MkVimball filename

    	on this range of lines will create a file called "filename.vba" which
    	can be used by Vimball.vim to re-create these files.  If the
    	"filename.vba" file already exists, then MkVimball will issue a
    	warning and not create the file.  Note that these paths are relative
    	to your .vim (vimfiles) directory, and the files should be in that
    	directory.  The vimball plugin normally uses the first |'runtimepath'|
    	directory that exists as a prefix; don't use absolute paths, unless
    	the user has specified such a path.

    	If you use the exclamation point (!), then MkVimball will create the
    	"filename.vba" file, overwriting it if it already exists.  This
    	behavior resembles that for |:w|.

    							*g:vimball_mkdir*
    	First, the |mkdir()| command is tried (not all systems support it).

    	If it doesn't exist, then g:vimball_mkdir doesn't exist, it is set to:
    	  |g:netrw_local_mkdir|, if it exists
    	   "mkdir", if it is executable
    	   "makedir", if it is executable
    	   Otherwise, it is undefined.
    	One may explicitly specify the directory making command using
    	g:vimball_mkdir.  This command is used to make directories that
    	are needed as indicated by the vimball.

    							*g:vimball_home*
    	You may override the use of the |'runtimepath'| by specifying a
    	variable, g:vimball_home.

    	Path Preprocessing				*g:vimball_path_escape*

    	Paths used in vimball are preprocessed by s:Path(); in addition,
    	certain characters are escaped (by prepending a backslash).  The
    	characters are in g:vimball_path_escape, and may be overridden by
    	the user in his/her .vimrc initialization script.

    							*vimball-extract*
    		vim filename.vba

    	Simply editing a Vimball will cause Vimball.vim to tell the user to
    	source the file to extract its contents.

    	Extraction will only proceed if the first line of a putative vimball
    	file holds the "Vimball Archiver by Charles E. Campbell, Jr., Ph.D."
    	line.

    		:VimballList				*:VimballList*

    	This command will tell Vimball to list the files in the archive, along
    	with their lengths in lines.

    		:UseVimball [path]			*:UseVimball*

    	This command is contained within the vimball itself; it invokes the
    	vimball#Vimball() routine which is responsible for unpacking the
    	vimball.  One may choose to execute it by hand instead of sourcing
    	the vimball; one may also choose to specify a path for the
    	installation, thereby overriding the automatic choice of the first
    	existing directory on the |'runtimepath'|.

    		:RmVimball vimballfile [path]		*:RmVimball*

    	This command removes all files generated by the specified vimball
    	(but not any directories it may have made).  One may choose a path
    	for de-installation, too (see |'runtimepath'|); otherwise, the
    	default is the first existing directory on the |'runtimepath'|.
    	To implement this, a file (.VimballRecord) is made in that directory
    	containing a record of what files need to be removed for all vimballs
    	used thus far.

    4. Vimball History					*vimball-history* {{{1

    	26 : May 27, 2008 * g:vimball_mkdir usage installed.  Makes the
    	                    $HOME/.vim (or $HOME\vimfiles) directory if
    			    necessary.
    	     May 30, 2008 * (tnx to Bill McCarthy) found and fixed a bug:
    			    vimball wasn't updating plugins to AsNeeded/
    			    when it should
    	25 : Mar 24, 2008 * changed vimball#Vimball() to recognize doc/*.??x
    			    files as help files, too.
    	     Apr 18, 2008 * RmVimball command is now protected by saving and
    	                    restoring settings -- in particular, acd was
    			    causing problems as reported by Zhang Shuhan
    	24 : Nov 15, 2007 * |g:vimball_path_escape| used by s:Path() to
    	                    prevent certain characters from causing trouble
    	22 : Mar 21, 2007 * uses setlocal instead of set during BufEnter
    	21 : Nov 27, 2006 * (tnx to Bill McCarthy) vimball had a header
    	                    handling problem and it now changes \s to /s
    	20 : Nov 20, 2006 * substitute() calls have all had the 'e' flag
    	                    removed.
    	18 : Aug 01, 2006 * vimballs now use folding to easily display their
    	                    contents.
    			  * if a user has AsNeeded/somefile, then vimball
    			    will extract plugin/somefile to the AsNeeded/
    			    directory
    	17 : Jun 28, 2006 * changes all \s to /s internally for Windows
    	16 : Jun 15, 2006 * A. Mechelynck's idea to allow users to specify
    			    installation root paths implemented for
    			    UseVimball, MkVimball, and RmVimball.
    			  * RmVimball implemented
    	15 : Jun 13, 2006 * bugfix
    	14 : May 26, 2006 * bugfixes
    	13 : May 01, 2006 * exists("&acd") used to determine if the acd
    			    option exists
    	12 : May 01, 2006 * bugfix - the |'acd'| option is not always defined
    	11 : Apr 27, 2006 * VimballList would create missing subdirectories that
    			    the vimball specified were needed.  Fixed.
    	10 : Apr 27, 2006 * moved all setting saving/restoration to a pair of
    			    functions.  Included some more settings in them
    			    which frequently cause trouble.
    	9  : Apr 26, 2006 * various changes to support Windows' predilection
    			    for backslashes and spaces in file and directory
    			    names.
    	7  : Apr 25, 2006 * bypasses foldenable
    			  * uses more exe and less norm! (:yank :put etc)
    			  * does better at insuring a "Press ENTER" prompt
    			    appears to keep its messages visible
    	4  : Mar 31, 2006 * BufReadPost seems to fire twice; BufReadEnter
    			    only fires once, so the "Source this file..."
    			    message is now issued only once.
    	3  : Mar 20, 2006 * removed query, now requires sourcing to be
    			    extracted (:so %).  Message to that effect
    			    included.
    			  * :VimballList  now shows files that would be
    			    extracted.
    	2  : Mar 20, 2006 * query, :UseVimball included
    	1  : Mar 20, 2006 * initial release
