    2. Usage					*tar-usage* *tar-manual*

       When one edits a *.tar file, this plugin will handle displaying a
       contents page.  Select a file to edit by moving the cursor atop
       the desired file, then hit the <return> key.  After editing, one may
       also write to the file.  Currently, one may not make a new file in
       tar archives via the plugin.

    						*:Vimuntar*
       VIMUNTAR

       :Vimuntar [vimhome]

    	This command copies, if necessary, the tarball to the .vim or vimfiles
    	directory using the first writable directory in the |'runtimepath'|
    	when no [vimhome] is specified.  Otherwise, the [vimhome] argument
    	allows the user to specify that directory, instead.

    	The copy is done using the command in *g:tar_copycmd* , which is
    		cp   for cygwin, unix, macunix
    		copy for windows (32, 95, 64, 16)
     	The extraction is done with the command specified with

    	*g:tar_extractcmd* , which by default is
    		"tar -xf"

    						*:TarDiff*
       DIFFERENCING SUPPORT

       :TarDiff [filename]

    	This command will attempt to show the differences between the tarball
    	version of a file and the associated file on the system.  In order to
    	find that file on the system, the script uses the path associated with
    	the file mentioned in the tarball.  If the current directory is not
    	correct for that path, :TarDiff will fail to find the associated file.

    	If the [filename] is given, that that filename (and path) will be used
    	to specify the associated file.

       PREVENTING LOADING

       If for some reason you do not wish to use vim to examine tar'd files,
       you may put the following two variables into your <.vimrc> to prevent
       the tar plugin from loading:

    	let g:loaded_tarPlugin= 1
    	let g:loaded_tar      = 1

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

    3. Options						*tar-options*

       These options are variables that one may change, typically in one's
       <.vimrc> file.
                             Default
       Variable               Value   Explanation

       *g:tar_browseoptions*  "Ptf"   used to get a list of contents

       *g:tar_readoptions*    "OPxf"  used to extract a file from a tarball

       *g:tar_cmd*            "tar"   the name of the tar program

       *g:tar_nomax*            0     if true, file window will not be maximized

       *g:tar_secure*         undef   if exists:
    					"--"s will be used to prevent unwanted
    					option expansion in tar commands.
    					Please be sure that your tar command
    					accepts "--"; Posix compliant tar
    					utilities do accept them.
    				  if not exists:
    				  	The tar plugin will reject any tar
    					files or member files that begin with
    					"-"
    				  Not all tar's support the "--" which is why
    				  it isn't default.

       *g:tar_writeoptions*   "uf"    used to update/replace a file
