+The files in this directory represent the default Minify setup designed to ease
+integration with your site. This app will combine and minify your Javascript or
+CSS files and serve them with HTTP compression and cache headers.
+
+
+RECOMMENDED
+
+It's recommended to edit config.php to set $min_cachePath to a writeable
+(by PHP) directory on your system. This will improve performance.
+
+
+GETTING STARTED
+
+The quickest way to get started is to use the Minify URI Builder application
+on your website: http://example.com/min/builder/
+
+
+MINIFYING A SINGLE FILE
+
+Let's say you want to serve this file:
+ http://example.com/wp-content/themes/default/default.css
+
+Here's the "Minify URL" for this file:
+ http://example.com/min/?f=wp-content/themes/default/default.css
+
+In other words, the "f" argument is set to the file path from root without the
+initial "/". As CSS files may contain relative URIs, Minify will automatically
+"fix" these by rewriting them as root relative.
+
+
+COMBINING MULTIPLE FILES IN ONE DOWNLOAD
+
+Separate the paths given to "f" with commas.
+
+Let's say you have CSS files at these URLs:
+ http://example.com/scripts/jquery-1.2.6.js
+ http://example.com/scripts/site.js
+
+You can combine these files through Minify by requesting this URL:
+ http://example.com/min/?f=scripts/jquery-1.2.6.js,scripts/site.js
+
+
+SIMPLIFYING URLS WITH A BASE PATH
+
+If you're combining files that share the same ancestor directory, you can use
+the "b" argument to set the base directory for the "f" argument. Do not include
+the leading or trailing "/" characters.
+
+E.g., the following URLs will serve the exact same content:
+ http://example.com/min/?f=scripts/jquery-1.2.6.js,scripts/site.js,scripts/home.js
+ http://example.com/min/?b=scripts&f=jquery-1.2.6.js,site.js,home.js
+
+
+MINIFY URLS IN HTML
+
+In (X)HTML files, don't forget to replace any "&" characters with "&amp;".
+
+
+SPECIFYING ALLOWED DIRECTORIES
+
+By default, Minify will serve any *.css/*.js files within the DOCUMENT_ROOT. If
+you'd prefer to limit Minify's access to certain directories, set the
+$min_serveOptions['minApp']['allowDirs'] array in config.php. E.g. to limit
+to the /js and /themes/default directories, use:
+
+$min_serveOptions['minApp']['allowDirs'] = array('//js', '//themes/default');
+
+
+GROUPS: FASTER PERFORMANCE AND BETTER URLS
+
+For the best performance, edit groupsConfig.php to pre-specify groups of files
+to be combined under preset keys. E.g., here's an example configuration in
+groupsConfig.php:
+
+return array(
+ 'js' => array('//js/Class.js', '//js/email.js')
+);
+
+This pre-selects the following files to be combined under the key "js":
+ http://example.com/js/Class.js
+ http://example.com/js/email.js
+
+You can now serve these files with this simple URL:
+ http://example.com/min/?g=js
+
+
+GROUPS: SPECIFYING FILES OUTSIDE THE DOC_ROOT
+
+In the groupsConfig.php array, the "//" in the file paths is a shortcut for
+the DOCUMENT_ROOT, but you can also specify paths from the root of the filesystem
+or relative to the DOC_ROOT:
+
+return array(
+ 'js' => array(
+ '//js/file.js' // file within DOC_ROOT
+ ,'//../file.js' // file in parent directory of DOC_ROOT
+ ,'C:/Users/Steve/file.js' // file anywhere on filesystem
+ )
+);
+
+
+FAR-FUTURE EXPIRES HEADERS
+
+Minify can send far-future (one year) Expires headers. To enable this you must
+add a number to the querystring (e.g. /min/?g=js&1234 or /min/f=file.js&1234)
+and alter it whenever a source file is changed. If you have a build process you
+can use a build/source control revision number.
+
+If you serve files as a group, you can use the utility function Minify_groupUri()
+to get a "versioned" Minify URI for use in your HTML. E.g.:
+
+<?php
+// add /min/lib to your include_path first!
+require $_SERVER['DOCUMENT_ROOT'] . '/min/utils.php';
+
+$jsUri = Minify_groupUri('js');
+echo "<script type='text/javascript' src='{$jsUri}'></script>";
+
+
+DEBUG MODE
+
+In debug mode, instead of compressing files, Minify sends combined files with
+comments prepended to each line to show the line number in the original source
+file. To enable this, set $min_allowDebugFlag to true in config.php and append
+"&debug=1" to your URIs. E.g. /min/?f=script1.js,script2.js&debug=1
+
+Known issue: files with comment-like strings/regexps can cause problems in this mode.

+<p>To do this, add a line like this to /min/groupsConfig.php:</p>
+
+<pre><code>return array(
+ <span style="color:#666">... your existing groups here ...</span>
+<input id=groupConfig size=100 type=text readonly>

+<h3>Find URIs on a Page</h3>
+<p>You can use the bookmarklet below to fetch all CSS &amp; Javascript URIs from a page
+on your site. When you active it, this page will open in a new window with a list of
+available URIs to add.</p>
+
+<p><a id=bm>Create Minify URIs</a> <small>(right-click, add to bookmarks)</small></p>
+</div>
+
+<h3>Combining CSS files that contain <code>@import</code></h3>
+<p>If your CSS files contain <code>@import</code> declarations, Minify will not
+remove them. Therefore, you will want to remove those that point to files already
+in your list, and move any others to the top of the first file in your list
+(imports below any styles will be ignored by browsers as invalid).</p>
+<p>If you desire, you can use Minify URIs in imports and they will not be touched
+by Minify. E.g. <code>@import "<span class=minRoot>/min/?</span>g=css2";</code></p>

+ * Converts to and from JSON format.
+ *
+ * JSON (JavaScript Object Notation) is a lightweight data-interchange
+ * format. It is easy for humans to read and write. It is easy for machines
+ * to parse and generate. It is based on a subset of the JavaScript
+ * Programming Language, Standard ECMA-262 3rd Edition - December 1999.
+ * This feature can also be found in Python. JSON is a text format that is
+ * completely language independent but uses conventions that are familiar
+ * to programmers of the C-family of languages, including C, C++, C#, Java,
+ * JavaScript, Perl, TCL, and many others. These properties make JSON an
+ * ideal data-interchange language.
+ *
+ * This package provides a simple encoder and decoder for JSON notation. It
+ * is intended for use with client-side Javascript applications that make
+ * use of HTTPRequest to perform server communication functions - data can
+ * be encoded into JSON notation for use in a client-side javascript, or
+ * decoded from incoming Javascript requests. JSON format is native to
+ * Javascript, and can be directly eval()'ed with no further parsing
+ * overhead
+ *
+ * All strings should be in ASCII or UTF-8 format!

+ * jsmin.php - PHP implementation of Douglas Crockford's JSMin.

+ *
+ * Comments containing IE conditional compilation are preserved, as are multi-line
+ * comments that begin with "/*!" (for documentation purposes). In the latter case
+ * newlines are inserted around the comment to enhance readability.
+ *
+ * PHP 5 or higher is required.

+ *
+ * 'quiet' : set to true to have serve() return an array rather than sending
+ * any headers/output (default false)
+ *
+ * 'encodeOutput' : set to false to disable content encoding, and not send
+ * the Vary header (default true)
+ *
+ * 'encodeMethod' : generally you should let this be determined by
+ * HTTP_Encoder (leave null), but you can force a particular encoding
+ * to be returned, by setting this to 'gzip' or '' (no encoding)
+ *
+ * 'encodeLevel' : level of encoding compression (0 to 9, default 9)
+ *
+ * 'contentTypeCharset' : appended to the Content-Type header sent. Set to a falsey
+ * value to remove. (default 'utf-8')
+ *
+ * 'maxAge' : set this to the number of seconds the client should use its cache
+ * before revalidating with the server. This sets Cache-Control: max-age and the
+ * Expires header. Unlike the old 'setExpires' setting, this setting will NOT
+ * prevent conditional GETs. Note this has nothing to do with server-side caching.
+ *
+ * 'rewriteCssUris' : If true, serve() will automatically set the 'currentDir'
+ * minifier option to enable URI rewriting in CSS files (default true)
+ *
+ * 'bubbleCssImports' : If true, all @import declarations in combined CSS
+ * files will be move to the top. Note this may alter effective CSS values
+ * due to a change in order. (default false)
+ *
+ * 'debug' : set to true to minify all sources with the 'Lines' controller, which
+ * eases the debugging of combined files. This also prevents 304 responses.
+ * @see Minify_Lines::minify()
+ *
+ * 'minifiers' : to override Minify's default choice of minifier function for
+ * a particular content-type, specify your callback under the key of the
+ * content-type:
+ * <code>
+ * // call customCssMinifier($css) for all CSS minification
+ * $options['minifiers'][Minify::TYPE_CSS] = 'customCssMinifier';
+ *
+ * // don't minify Javascript at all
+ * $options['minifiers'][Minify::TYPE_JS] = '';
+ * </code>
+ *
+ * 'minifierOptions' : to send options to the minifier function, specify your options
+ * under the key of the content-type. E.g. To send the CSS minifier an option:
+ * <code>
+ * // give CSS minifier array('optionName' => 'optionValue') as 2nd argument
+ * $options['minifierOptions'][Minify::TYPE_CSS]['optionName'] = 'optionValue';
+ * </code>
+ *
+ * 'contentType' : (optional) this is only needed if your file extension is not
+ * js/css/html. The given content-type will be sent regardless of source file
+ * extension, so this should not be used in a Groups config with other
+ * Javascript/CSS files.
+ *
+ * Any controller options are documented in that controller's setupSources() method.
+ *
+ * @param mixed instance of subclass of Minify_Controller_Base or string name of
