system/3rd_party/Minify/MIN.txt

@@ -1,145 +0,0 @@
-The files in the /min/ 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 /min/config.php to set $min_cachePath to a writeable
-(by PHP) directory on your system. This will improve performance.
-
-
-GETTING STARTED
-
-The quickest way to get started is to use the Minify URI Builder application
-on your website: http://example.com/min/builder/
-
-
-MINIFYING A SINGLE FILE
-
-Let's say you want to serve this file:
-  http://example.com/wp-content/themes/default/default.css
-
-Here's the "Minify URL" for this file:
-  http://example.com/min/?f=wp-content/themes/default/default.css
-
-In other words, the "f" argument is set to the file path from root without the
-initial "/". As CSS files may contain relative URIs, Minify will automatically
-"fix" these by rewriting them as root relative.
-
-
-COMBINING MULTIPLE FILES IN ONE DOWNLOAD
-
-Separate the paths given to "f" with commas.
-
-Let's say you have CSS files at these URLs:
-  http://example.com/scripts/jquery-1.2.6.js
-  http://example.com/scripts/site.js
-
-You can combine these files through Minify by requesting this URL:
-  http://example.com/min/?f=scripts/jquery-1.2.6.js,scripts/site.js
-
-
-SIMPLIFYING URLS WITH A BASE PATH
-
-If you're combining files that share the same ancestor directory, you can use
-the "b" argument to set the base directory for the "f" argument. Do not include
-the leading or trailing "/" characters.
-
-E.g., the following URLs will serve the exact same content:
-  http://example.com/min/?f=scripts/jquery-1.2.6.js,scripts/site.js,scripts/home.js
-  http://example.com/min/?b=scripts&f=jquery-1.2.6.js,site.js,home.js
-
-
-MINIFY URLS IN HTML
-
-In HTML files, don't forget to replace any "&" characters with "&".
-
-
-SPECIFYING ALLOWED DIRECTORIES
-
-By default, Minify will serve any *.css/*.js files within the DOCUMENT_ROOT. If
-you'd prefer to limit Minify's access to certain directories, set the
-$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: NICER URLS
-
-For nicer URLs, 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
-    )
-);
-
-
-COMBINE MULTIPLE GROUPS AND FILES IN ONE URL
-
-E.g.: http://example.com/min/?g=js&f=more/scripts.js
-
-Separate group keys with commas:
-  http://example.com/min/?g=baseCss,css1&f=moreStyles.css
-
-
-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.
-
-You can alternately use the utility function Minify_getUri() to get a "versioned"
-Minify URI for use in your HTML. E.g.:
-
-<?php
-require $_SERVER['DOCUMENT_ROOT'] . '/min/utils.php';
-
-$jsUri = Minify_getUri('js'); // a key in groupsConfig.php
-echo "<script src='{$jsUri}'></script>";
-
-$cssUri = Minify_getUri(array(
-     '//css/styles1.css'
-    ,'//css/styles2.css'
-)); // a list of files
-echo "<link rel=stylesheet href='{$cssUri}'>";
-
-
-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.

-WELCOME TO MINIFY!
-
-Minify is an HTTP content server. It compresses sources of content 
-(usually files), combines the result and serves it with appropriate 
-HTTP headers. These headers can allow clients to perform conditional 
-GETs (serving content only when clients do not have a valid cache) 
-and tell clients to cache the file for a period of time. 
-More info: http://code.google.com/p/minify/
-
-
-WORDPRESS USER?
-
-These WP plugins integrate Minify into WordPress's style and script hooks to
-get you set up faster.
-  http://wordpress.org/extend/plugins/bwp-minify/
-  http://wordpress.org/extend/plugins/w3-total-cache/
-
-
-INSTALLATION
-
-Place the /min/ directory as a child of your DOCUMENT_ROOT
-directory: i.e. you will have: /home/example/www/min
-
-You can see verify that it is working by visiting these two URLs:
-  http://example.org/min/?f=min/quick-test.js
-  http://example.org/min/?f=min/quick-test.css
-
-If your server supports mod_rewrite, this URL should also work:
-  http://example.org/min/f=min/quick-test.js
-
-CONFIGURATION & USAGE
-
-See the MIN.txt file and http://code.google.com/p/minify/wiki/UserGuide
-
-Minify also comes with a URI Builder application that can help you write URLs
-for use with Minify or configure groups of files. See here for details:
-  http://code.google.com/p/minify/wiki/BuilderApp
-
-The cookbook also provides some more advanced options for minification:
-  http://code.google.com/p/minify/wiki/CookBook
-
-UPGRADING
-
-See UPGRADING.txt for instructions.
-
-
-UNIT TESTING:
-
-1. Place the /min_unit_tests/ directory as a child of your DOCUMENT_ROOT 
-directory: i.e. you will have: /home/example/www/min_unit_tests
-
-2. To run unit tests, access: http://example.org/min_unit_tests/test_all.php
-
-(If you wish, the other test_*.php files can be run to test individual
-components with more verbose output.)
-
-3. Remove /min_unit_tests/ from your DOCUMENT_ROOT when you are done.
-
-
-FILE ENCODINGS
-
-Minify *should* work fine with files encoded in UTF-8 or other 8-bit 
-encodings like ISO 8859/Windows-1252. By default Minify appends
-";charset=utf-8" to the Content-Type headers it sends. 
-
-Leading UTF-8 BOMs are stripped from all sources to prevent 
-duplication in output files, and files are converted to Unix newlines.

-<h2>Minify URI</h2>
-<p>Place this URI in your HTML to serve the files above combined, minified, compressed and
-with cache headers.</p>
-<table id=uriTable>
-    <tr><th>URI</th><td><a id=uriA class=ext>/min</a> <small>(opens in new window)</small></td></tr>
-    <tr><th>HTML</th><td><input id=uriHtml type=text size=100 readonly></td></tr>
-</table>
-
-<h2>How to serve these files as a group</h2>
-<p>For the best performance you can serve these files as a pre-defined group with a URI
-like: <code><span class=minRoot>/min/?</span>g=keyName</code></p>
-<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>
-);</code></pre>
-
-<p><em>Make sure to replace <code>keyName</code> with a unique key for this group.</em></p>

-<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>
-
-<h3>Debug Mode</h3>
-<p>When /min/config.php has <code>$min_allowDebugFlag = <strong>true</strong>;</code>
- you can get debug output by appending <code>&amp;debug</code> to a Minify URL, or
- by sending the cookie <code>minDebug=&lt;match&gt;</code>, where <code>&lt;match&gt;</code>
- should be a string in the Minify URIs you'd like to debug. This bookmarklet will allow you to
- set this cookie.</p>
