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"
<
   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
