-An embryonic MasterKey Widget Set
-=================================
-
-This directory contains an embryonic MasterKey Widget Set, based
-initially on "jsdemo" though now far removed from those beginnnings.
-
-
-How this works
---------------
-
-The goal is to make it that as much of the searching functionality as
-possible is hosted on
-	http://mkws.indexdata.com/
-so that very simple websites such as
-	http://somesite.indexdata.com/
-can have MasterKey searching with minimal effort.
-
-The following files must be hosted on mkws.indexdata.com:
-	mkws.js
-	mkwsStyle.css
-	/libjs-pz2/pz2api.1.js (*)
-
-The following files make up the application:
-	index.html
-	favicon.ico [optional]
-	robots.txt [optional]
-
-(At present, the client application's configuruation also needs an
-Alias for /service-proxy/, to avoid cross-site scripting issues. We
-will fix this.)
-
-(*) if you don't have already installed libjs-pz2 on the machine, you can
-do it by installing a debian package or check it out from GIT:
-$ git clone ssh://git.indexdata.com:222/home/git/pub/libjs-pz2
-
-Configuring a client
---------------------
-
-The application's HTML must contains the following elements as well as
-whatever makes up the application itself:
-
-Prerequisites:
-    <link rel="stylesheet" href="mkwsStyle.css" />
-    <script type="text/javascript">
-	var mkws_config = { };
-    </script>
-    <script type="text/javascript" src="http://code.jquery.com/jquery-1.10.0.min.js"></script>
-    <script type="text/javascript" src="/libjs-pz2/pz2api.1.js"></script>
-    <script type="text/javascript" src="mkws.js"></script>
-(Yes, we're using JQuery. We use it only in the most trivial ways, and
-could probably get rid of it without too much pain. I'd like to have
-mkws.js automatically pull in pz2api.1.js, too, so you don't need to
-do so many things, but that's not quite trivial.)
-
-Then the following special <div>s can be added (with no content), and
-will be filled in by MKWS:
-    <div id="mkwsSwitch"></div> -- switch between record and target views
-    <div id="mkwsLang"></div>   -- switch between English, Danish and German
-    <div id="mkwsSearch"></div> -- search box and button
-    <div id="mkwsResults"></div> -- result list, including pager/sorting
-    <div id="mkwsTargets"></div> -- target list, including status
-    <div id="mkwsStat"></div> -- summary statistics
-
-At present, MKWS will not work correctly if any of these is
-missing. One of the TODOs is to fix it so that it doesn't try to use
-whatever is not there, and just uses what is.
-
-
-You can configure and control the client with the JavaScript mkws_config object.
-
-Here is an example of all possible options
-    <script type="text/javascript">
-        var mkws_config = {
-                use_service_proxy: true,    /* true, flase: use service proxy instead pazpar2 */
-		switch_menu: true, 	    /* true, false: show/hide Records|Targets menu */
-		lang_menu: true, 	    /* true, false: show/hide language menu */
-		sort_menu: true, 	    /* true, false: show/hide sort menu */
-		perpage_menu: true, 	    /* true, false: show/hide perpage menu */
-	        lang_display: ["en", "de", "da"], /* display languages links for given
-				                     languages, [] for all */
-		facets: ["sources", "subjects", "authors"], /* display facets, in this order, [] for none */
-                sort_default: "relevance",  /* "relevance", "title:1", "date:0", "date:1" */
-		query_width: 50,	    /* 5..50 */
-                perpage_default: 20,	    /* 10, 20, 30, 50 */
-                lang: "en",                 /* "en", "de", "da" */
-		debug: 0,     		    /* debug level for development: 0..2 */
-
-		responsive_design: false    /* true, false: resize for smaller mobile devices */
-		pazpar2_url: "/pazpar2/search.pz2",   	   /* URL */
-		service_proxy_url: "/service-proxy/", 	   /* URL */
-		service_proxy_auth: "/service-proxy-auth", /* URL */
-         };
-    </script>
-
-Note: the mkws_config object which must be loaded before the mkws.js and pz2api.js files.
-
-Supported Browsers
-------------------
-
-Any modern HTML5 browser will work fine. JavaScript must be enabled.
-
-* IE8 or later
-* Firefox 17 or later
-* Google Chrome 27 or later
-* Safari 6 or later
-* Opera  12 or later
-* iOS 6.x (iPhone, iPad)
-* Android 4.x
-
-Not supported: IE6, IE7
-
-New Features since jsdemo
---------------------------
-- multilinguality: English (default), Danish, German
-- depends on the new pazpar2 JS library libjs-pz2/pz2api.1.js
-  which will make the development of pazpar2 plugins faster and
-  easier to share code between projects
-- supports basic pazpar2 and service-proxy requests
-- simplified HTML
-- the search page is fully configurable by a JSON object
-
-
-What next?
-----------
-
-Main areas of work:
-* Make MKWS robust to missing widgets
-* Clean up the code

-          Note. This is not yet quite true: the stylesheet needs tweaking
-          to make it more specific to only the MKWS components. At present

-        </p>

-      For examples of how to use the widget-set, see:
-    </p>
-    <ul>
-      <li>
-        A very simple application at
-        <a href="http://somesite.indexdata.com/"
-                >http://somesite.indexdata.com/</a>.
-        It's worth viewing the source to see how small it is.
-      </li>
-      <li>
-        <a href="http://somesite.indexdata.com/index-full.html"
-           >A more detailed version</a>
-	that contains a configuration structure instead of accepting
-        the defaults. Includes a custom translation option to present
-        the application in Arabic.
-      </li>
-      <li>
-        The
-        <a href="http://somesite.indexdata.com/index-jquery.html"
-           >jQuery plugin</a>
-        version, consisting of a single line of JavaScript code.
-      </li>
-      <li>
-	An application that
-	<a href="http://somesite.indexdata.com/index-lowlevel.html"
-	   >uses lower-level MKWS components</a>
-	rather than the all-in-one <tt>#mkwsResults</tt> division,
-	allowing it to use a rather different layout.
-      </li>
-      <li>
-        <a href="http://somesite.indexdata.com/index-mobile.html"
-           >A version suitable for mobile devices</a>,
-	with a responsive design that moves components around
-        depending on the screen size.
-      </li>
-      <li>
-        <a href="http://somesite.indexdata.com/index-popup.html"
-           >A version that uses a jQuery popup</a>.
-      </li>
-      <li>
-        An existing web-site,
-        <a href="http://sagp.miketaylor.org.uk/"
-           >The Self-Appointed Grammar Police</a>,
-        which has been fitted with an MKWS searching widget.
-        (See also the MKWS-widget customisations in
-        <a href="http://sagp.miketaylor.org.uk/style.css"
-           >that site's stylesheet</a>.)
-      </li>

-	Another existing web-site,
-        <a href="http://zthes.z3950.org/"
-           >The Zthes specifications</a>,
-	which has been fitted with a popup MKWS search-box.
-      </li>
-    </ul>
-    <p>
-      The set of targets can be maintained:
-    </p>
-    <ul>
-      <li>
-	Use the main
-	<a href="http://mk2.indexdata.com/console/"
-	   >MasterKey Admin Console</a>,
-	and act as the "MK Demo" library administrator.
-      </li>
-    </ul>
-    <p>
-      Documentation is as yet in short supply:
-    </p>
-    <ul>
-      <li>
-        The <a href="README"
-               >README</a> (which may not be fully up to
-        date).
-      </li>
-      <li>
-        The <a href="html-structure.txt"
-               >structure of the HTML generated by the MKWS widgets</a>,
-        which can be used to guide the customisation of its CSS styles.

+An embryonic MasterKey Widget Set
+=================================
+
+This directory contains an embryonic MasterKey Widget Set, based
+initially on "jsdemo" though now far removed from those beginnnings.
+
+
+How this works
+--------------
+
+The goal is to make it that as much of the searching functionality as
+possible is hosted on
+	http://mkws.indexdata.com/
+so that very simple websites such as
+	http://example.indexdata.com/
+can have MasterKey searching with minimal effort.
+
+The following files must be hosted on mkws.indexdata.com:
+	mkws.js
+	mkwsStyle.css
+	/libjs-pz2/pz2api.1.js (*)
+
+The following files make up the application:
+	index.html
+	favicon.ico [optional]
+	robots.txt [optional]
+
+(At present, the client application's configuruation also needs an
+Alias for /service-proxy/, to avoid cross-site scripting issues. We
+will fix this.)
+
+(*) if you don't have already installed libjs-pz2 on the machine, you can
+do it by installing a debian package or check it out from GIT:
+$ git clone ssh://git.indexdata.com:222/home/git/pub/libjs-pz2
+
+Configuring a client
+--------------------
+
+The application's HTML must contains the following elements as well as
+whatever makes up the application itself:
+
+Prerequisites:
+    <link rel="stylesheet" href="mkwsStyle.css" />
+    <script type="text/javascript">
+	var mkws_config = { };
+    </script>
+    <script type="text/javascript" src="http://code.jquery.com/jquery-1.10.0.min.js"></script>
+    <script type="text/javascript" src="/libjs-pz2/pz2api.1.js"></script>
+    <script type="text/javascript" src="mkws.js"></script>
+(Yes, we're using JQuery. We use it only in the most trivial ways, and
+could probably get rid of it without too much pain. I'd like to have
+mkws.js automatically pull in pz2api.1.js, too, so you don't need to
+do so many things, but that's not quite trivial.)
+
+Then the following special <div>s can be added (with no content), and
+will be filled in by MKWS:
+    <div id="mkwsSwitch"></div> -- switch between record and target views
+    <div id="mkwsLang"></div>   -- switch between English, Danish and German
+    <div id="mkwsSearch"></div> -- search box and button
+    <div id="mkwsResults"></div> -- result list, including pager/sorting
+    <div id="mkwsTargets"></div> -- target list, including status
+    <div id="mkwsStat"></div> -- summary statistics
+
+At present, MKWS will not work correctly if any of these is
+missing. One of the TODOs is to fix it so that it doesn't try to use
+whatever is not there, and just uses what is.
+
+
+You can configure and control the client with the JavaScript mkws_config object.
+
+Here is an example of all possible options
+    <script type="text/javascript">
+        var mkws_config = {
+                use_service_proxy: true,    /* true, flase: use service proxy instead pazpar2 */
+		switch_menu: true, 	    /* true, false: show/hide Records|Targets menu */
+		lang_menu: true, 	    /* true, false: show/hide language menu */
+		sort_menu: true, 	    /* true, false: show/hide sort menu */
+		perpage_menu: true, 	    /* true, false: show/hide perpage menu */
+	        lang_display: ["en", "de", "da"], /* display languages links for given
+				                     languages, [] for all */
+		facets: ["sources", "subjects", "authors"], /* display facets, in this order, [] for none */
+                sort_default: "relevance",  /* "relevance", "title:1", "date:0", "date:1" */
+		query_width: 50,	    /* 5..50 */
+                perpage_default: 20,	    /* 10, 20, 30, 50 */
+                lang: "en",                 /* "en", "de", "da" */
+		debug: 0,     		    /* debug level for development: 0..2 */
+
+		responsive_design: false    /* true, false: resize for smaller mobile devices */
+		pazpar2_url: "/pazpar2/search.pz2",   	   /* URL */
+		service_proxy_url: "/service-proxy/", 	   /* URL */
+		service_proxy_auth: "/service-proxy-auth", /* URL */
+         };
+    </script>
+
+Note: the mkws_config object which must be loaded before the mkws.js and pz2api.js files.
+
+Supported Browsers
+------------------
+
+Any modern HTML5 browser will work fine. JavaScript must be enabled.
+
+* IE8 or later
+* Firefox 17 or later
+* Google Chrome 27 or later
+* Safari 6 or later
+* Opera  12 or later
+* iOS 6.x (iPhone, iPad)
+* Android 4.x
+
+Not supported: IE6, IE7
+
+New Features since jsdemo
+--------------------------
+- multilinguality: English (default), Danish, German
+- depends on the new pazpar2 JS library libjs-pz2/pz2api.1.js
+  which will make the development of pazpar2 plugins faster and
+  easier to share code between projects
+- supports basic pazpar2 and service-proxy requests
+- simplified HTML
+- the search page is fully configurable by a JSON object
+
+
+What next?
+----------
+
+Main areas of work:
+* Make MKWS robust to missing widgets
+* Clean up the code
