    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.

    								*zip-x*
       x : may extract a listed file when the cursor is atop it

       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"

    							*g:zip_extractcmd*
       This option specifies the program (and any options needed) used to
       extract a file from a zip archive.  By default,
       	let g:zip_extractcmd= g:zip_unzipcmd

       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 which 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.

       Alternatively, one may change *g:zipPlugin_ext* in one's .vimrc.
       Currently (11/30/15) it holds:

    	let g:zipPlugin_ext= '*.zip,*.jar,*.xpi,*.ja,*.war,*.ear,*.celzip,
           \ *.oxt,*.kmz,*.wsz,*.xap,*.docx,*.docm,*.dotx,*.dotm,*.potx,*.potm,
           \ *.ppsx,*.ppsm,*.pptx,*.pptm,*.ppam,*.sldx,*.thmx,*.xlam,*.xlsx,*.xlsm,
           \ *.xlsb,*.xltx,*.xltm,*.xlam,*.crtx,*.vdw,*.glox,*.gcsx,*.gqsx,*.epub'

    4. History							*zip-history* {{{1
       v28 Oct 08, 2014 * changed the sanity checks for executables to reflect
       		      the command actually to be attempted in zip#Read()
    		      and zip#Write()
    		    * added the extraction of a file capability
           Nov 30, 2015 * added *.epub to the |g:zipPlugin_ext| list
           Sep 13, 2016 * added *.apk to the |g:zipPlugin_ext| list and
    		      sorted the suffices.
       v27 Jul 02, 2013 * sanity check: zipfile must have "PK" as its first
    		      two bytes.
    		    * modified to allow zipfile: entries in quickfix lists
       v26 Nov 15, 2012 * (Jason Spiro) provided a lot of new extensions that
    		      are synonyms for .zip
       v25 Jun 27, 2011 * using keepj with unzip -Z
    		      (consistent with the -p variant)
    		    * (Ben Staniford) now uses
    			has("win32unix") && executable("cygpath")
    		      before converting to cygwin-style paths
       v24 Jun 21, 2010 * (Cédric Bosdonnat) unzip seems to need its filenames
    		      fnameescape'd as well as shellquote'd
    		    * (Motoya Kurotsu) inserted keepj before 0d to protect
    		      jump list
       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)

                       * began testing under Windows; works thus far
    		   * filetype detection fixed
          Nov 03, 2005 * handles writing zipfiles across a network using
                         netrw#NetWrite()
