2. Usage					*zip-usage* *zip-manual*

   When one edits a *.zip 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
   zip archives via the plugin.

   OPTIONS

   							*g:zip_nomax*

   If this variable exists and is true, the file window will not be
   automatically maximized when opened.

							*g:zip_shq*
   Different operating systems may use one or more shells to execute
   commands.  Zip will try to guess the correct quoting mechanism to
   allow spaces and whatnot in filenames; however, if it is incorrectly
   guessing the quote to use for your setup, you may use >
	g:zip_shq
<  which by default is a single quote under Unix (') and a double quote
   under Windows (").  If you'd rather have no quotes, simply set
   g:zip_shq to the empty string (let g:zip_shq= "") in your <.vimrc>.

   							*g:zip_unzipcmd*
   Use this option to specify the program which does the duty of "unzip".
   It's used during browsing. By default: >
   	let g:zip_unzipcmd= "unzip"
<
							*g:zip_zipcmd*
   Use this option to specify the program which does the duty of "zip".
   It's used during the writing (updating) of a file already in a zip
   file; by default: >
   	let g:zip_zipcmd= "zip"
<
   PREVENTING LOADING~

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

	let g:loaded_zipPlugin= 1
	let g:loaded_zip      = 1
<

==============================================================================
3. Additional Extensions					*zip-extension*

   Apparently there are a number of archivers who generate zip files that
   don't use the .zip extension (.jar, .xpi, etc).  To handle such files,
   place a line in your <.vimrc> file: >

	au BufReadCmd *.jar,*.xpi call zip#Browse(expand("<amatch>"))
<
   One can simply extend this line to accommodate additional extensions that
   should be treated as zip files.

4. History					*zip-history* {{{1
   v17 May 09, 2008 * arno caught a security bug
   v15 Sep 07, 2007 * &shq now used if not the empty string for g:zip_shq
   v14 May 07, 2007 * using b:zipfile instead of w:zipfile to avoid problem
                      when editing alternate file to bring up a zipfile
   v10 May 02, 2006 * now using "redraw then echo" to show messages, instead
                      of "echo and prompt user"
		    * g:zip_shq provided to allow for quoting control for the
		      command being passed via :r! ... commands.
   v8 Apr 10, 2006 * Bram Moolenaar reported that he received an error message
                     due to "Pattern not found: ^.*\%0c"; this was caused by
		     stridx finding a Name... at the beginning of the line;
		     zip.vim tried 4,$s/^.*\%0c//, but that doesn't work.
		     Fixed.
   v7 Mar 22, 2006 * escaped some characters that can cause filename handling
                     problems.
   v6 Dec 21, 2005 * writing to files not in directories caused problems -
                     fixed (pointed out by Christian Robinson)
   v5 Nov 22, 2005 * report option workaround installed
   v3 Oct 18, 2005 * <amatch> used instead of <afile> in autocmds
   v2 Sep 16, 2005 * silenced some commands (avoiding hit-enter prompt)
                   * began testing under Windows; works thus far
		   * filetype detection fixed
      Nov 03, 2005 * handles writing zipfiles across a network using
                     netrw#NetWrite()
