     Admittedly, these letters are somewhat arbitrary; the only stipulation
     was that they couldn't be a through f. r is for resource (I would have preferred
     e, but you take what you can get), n is for name, m
     was picked because it came after n (and I couldn't use a), p is for
     property.

+// Note [Injector skips]
+// ~~~~~~~~~~~~~~~~~~~~~
+// When I originally designed this class, the idea behind the 'skip'
+// property of HTMLPurifier_Token was to help avoid infinite loops
+// in injector processing.  For example, suppose you wrote an injector
+// that bolded swear words.  Naively, you might write it so that
+// whenever you saw ****, you replaced it with <strong>****</strong>.
+//
+// When this happens, we will reprocess all of the tokens with the
+// other injectors.  Now there is an opportunity for infinite loop:
+// if we rerun the swear-word injector on these tokens, we might
+// see **** and then reprocess again to get
+// <strong><strong>****</strong></strong> ad infinitum.
+//
+// Thus, the idea of a skip is that once we process a token with
+// an injector, we mark all of those tokens as having "come from"
+// the injector, and we never run the injector again on these
+// tokens.
+//
+// There were two more complications, however:
+//
+//  - With HTMLPurifier_Injector_RemoveEmpty, we noticed that if
+//    you had <b><i></i></b>, after you removed the <i></i>, you
+//    really would like this injector to go back and reprocess
+//    the <b> tag, discovering that it is now empty and can be
+//    removed.  So we reintroduced the possibility of infinite looping
+//    by adding a "rewind" function, which let you go back to an
+//    earlier point in the token stream and reprocess it with injectors.
+//    Needless to say, we need to UN-skip the token so it gets
+//    reprocessed.
+//
+//  - Suppose that you successfuly process a token, replace it with
+//    one with your skip mark, but now another injector wants to
+//    process the skipped token with another token.  Should you continue
+//    to skip that new token, or reprocess it?  If you reprocess,
+//    you can end up with an infinite loop where one injector converts
+//    <a> to <b>, and then another injector converts it back.  So
+//    we inherit the skips, but for some reason, I thought that we
+//    should inherit the skip from the first token of the token
+//    that we deleted.  Why?  Well, it seems to work OK.
+//
+// If I were to redesign this functionality, I would absolutely not
+// go about doing it this way: the semantics are just not very well
+// defined, and in any case you probably wanted to operate on trees,
+// not token streams.

+/**
+ * An observer that saves response body to stream, possibly uncompressing it
+ *
+ * This Observer is written in compliment to pear's HTTP_Request2 in order to
+ * avoid reading the whole response body in memory. Instead it writes the body
+ * to a stream. If the body is transferred with content-encoding set to
+ * "deflate" or "gzip" it is decoded on the fly.
+ *
+ * The constructor accepts an already opened (for write) stream (file_descriptor).
+ * If the response is deflate/gzip encoded a "zlib.inflate" filter is applied
+ * to the stream. When the body has been read from the request and written to
+ * the stream ("receivedBody" event) the filter is removed from the stream.
+ *
+ * The "zlib.inflate" filter works fine with pure "deflate" encoding. It does
+ * not understand the "deflate+zlib" and "gzip" headers though, so they have to
+ * be removed prior to being passed to the stream. This is done in the "update"
+ * method.
+ *
+ * It is also possible to limit the size of written extracted bytes by passing
+ * "max_bytes" to the constructor. This is important because e.g. 1GB of
+ * zeroes take about a MB when compressed.
+ *
+ * Exceptions are being thrown if data could not be written to the stream or
+ * the written bytes have already exceeded the requested maximum. If the "gzip"
+ * header is malformed or could not be parsed an exception will be thrown too.
+ *
+ * Example usage follows:
+ *
+ * <code>
+ * require_once 'HTTP/Request2.php';
+ * require_once 'HTTP/Request2/Observer/UncompressingDownload.php';
+ *
+ * #$inPath = 'http://carsten.codimi.de/gzip.yaws/daniels.html';

+ * $inPath = 'http://carsten.codimi.de/gzip.yaws/daniels.html?deflate=on&zlib=on';
+ * #$outPath = "/dev/null";
+ * $outPath = "delme";
+ *
+ * $stream = fopen($outPath, 'wb');
+ * if (!$stream) {
+ *     throw new Exception('fopen failed');
+ * }
+ *
+ * $request = new HTTP_Request2(
+ *     $inPath,
+ *     HTTP_Request2::METHOD_GET,
+ *     array(

+Based on the [constant-time base64 implementation made by Steve "Sc00bz" Thomas](https://github.com/Sc00bz/ConstTimeEncoding),
+this library aims to offer character encoding functions that do not leak
+information about what you are encoding/decoding via processor cache 
+misses. Further reading on [cache-timing attacks](http://blog.ircmaxell.com/2014/11/its-all-about-time.html).
+
+Our fork offers the following enchancements:
+
+* `mbstring.func_overload` resistance
+* Unit tests
+* Composer- and Packagist-ready
+* Base16 encoding
+* Base32 encoding
+* Uses `pack()` and `unpack()` instead of `chr()` and `ord()`
+
+## PHP Version Requirements
+
+This library should work on any [supported version of PHP](https://secure.php.net/supported-versions.php).
+It *may* work on earlier versions, but we **do not** guarantee it. If it
+doesn't, we **will not** fix it to work on earlier versions of PHP.
+
+## How to Install
+
+```sh
+composer require paragonie/constant_time_encoding
+```
+
+## How to Use
+
+```php
+use \ParagonIE\ConstantTime\Encoding;
+
+// possibly (if applicable): 
+// require 'vendor/autoload.php';
+
+$data = random_bytes(32);
+echo Encoding::base64Encode($data), "\n";
+echo Encoding::base32EncodeUpper($data), "\n";
+echo Encoding::base32Encode($data), "\n";
+echo Encoding::hexEncode($data), "\n";
+echo Encoding::hexEncodeUpper($data), "\n";
+```
+
+Example output:
+ 
+```

+```
+
+If you only need a particular variant, you can just reference the 
+required class like so:
+
+```php
+use \ParagonIE\ConstantTime\Base64;
+use \ParagonIE\ConstantTime\Base32;
+
+$data = random_bytes(32);
+echo Base64::encode($data), "\n";
+echo Base32::encode($data), "\n";
+```
+
+Example output:
+
+```

+/**
+ * Pure-PHP implementation of AES.
+ *
+ * Uses mcrypt, if available/possible, and an internal implementation, otherwise.
+ *
+ * PHP version 5
+ *
+ * NOTE: Since AES.php is (for compatibility and phpseclib-historical reasons) virtually
+ * just a wrapper to Rijndael.php you may consider using Rijndael.php instead of
+ * to save one include_once().
+ *
+ * If {@link self::setKeyLength() setKeyLength()} isn't called, it'll be calculated from
+ * {@link self::setKey() setKey()}.  ie. if the key is 128-bits, the key length will be 128-bits.  If it's 136-bits
+ * it'll be null-padded to 192-bits and 192 bits will be the key length until {@link self::setKey() setKey()}
+ * is called, again, at which point, it'll be recalculated.
+ *
+ * Since \phpseclib\Crypt\AES extends \phpseclib\Crypt\Rijndael, some functions are available to be called that, in the context of AES, don't
+ * make a whole lot of sense.  {@link self::setBlockLength() setBlockLength()}, for instance.  Calling that function,
+ * however possible, won't do anything (AES has a fixed block length whereas Rijndael has a variable one).
+ *
+ * Here's a short example of how to use this library:
+ * <code>
+ * <?php
+ *    include 'vendor/autoload.php';
+ *
+ *    $aes = new \phpseclib\Crypt\AES();
+ *
+ *    $aes->setKey('abcdefghijklmnop');
+ *
+ *    $size = 10 * 1024;
+ *    $plaintext = '';
+ *    for ($i = 0; $i < $size; $i++) {
+ *        $plaintext.= 'a';
+ *    }
+ *
+ *    echo $aes->decrypt($aes->encrypt($plaintext));
+ * ?>
+ * </code>

+/**
+ * Pure-PHP implementation of RC4.
+ *
+ * Uses mcrypt, if available, and an internal implementation, otherwise.
+ *
+ * PHP version 5
+ *
+ * Useful resources are as follows:
+ *
+ *  - {@link http://www.mozilla.org/projects/security/pki/nss/draft-kaukonen-cipher-arcfour-03.txt ARCFOUR Algorithm}
+ *  - {@link http://en.wikipedia.org/wiki/RC4 - Wikipedia: RC4}
+ *
+ * RC4 is also known as ARCFOUR or ARC4.  The reason is elaborated upon at Wikipedia.  This class is named RC4 and not
+ * ARCFOUR or ARC4 because RC4 is how it is referred to in the SSH1 specification.
+ *
+ * Here's a short example of how to use this library:
+ * <code>
+ * <?php
+ *    include 'vendor/autoload.php';
+ *
+ *    $rc4 = new \phpseclib\Crypt\RC4();
+ *
+ *    $rc4->setKey('abcdefgh');
+ *
+ *    $size = 10 * 1024;
+ *    $plaintext = '';
+ *    for ($i = 0; $i < $size; $i++) {
+ *        $plaintext.= 'a';
+ *    }
+ *
+ *    echo $rc4->decrypt($rc4->encrypt($plaintext));
+ * ?>

+     * public key should have the second byte set to 2.  In RFC3447 (PKCS#1 v2.1), the second byte is supposed

+     * second byte is 2 or less.  If it is, we'll accept the decrypted string as valid.
+     *
+     * As a consequence of this, a private key encrypted ciphertext produced with \phpseclib\Crypt\RSA may not decrypt

+ * Pure-PHP implementation of Rijndael.

+ * Uses mcrypt, if available/possible, and an internal implementation, otherwise.
+ *
+ * PHP version 5
+ *
+ * If {@link self::setBlockLength() setBlockLength()} isn't called, it'll be assumed to be 128 bits.  If
+ * {@link self::setKeyLength() setKeyLength()} isn't called, it'll be calculated from
+ * {@link self::setKey() setKey()}.  ie. if the key is 128-bits, the key length will be 128-bits.  If it's
+ * 136-bits it'll be null-padded to 192-bits and 192 bits will be the key length until
+ * {@link self::setKey() setKey()} is called, again, at which point, it'll be recalculated.
+ *
+ * Not all Rijndael implementations may support 160-bits or 224-bits as the block length / key length.  mcrypt, for example,
+ * does not.  AES, itself, only supports block lengths of 128 and key lengths of 128, 192, and 256.
+ * {@link http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf#page=10 Rijndael-ammended.pdf#page=10} defines the
+ * algorithm for block lengths of 192 and 256 but not for block lengths / key lengths of 160 and 224.  Indeed, 160 and 224
+ * are first defined as valid key / block lengths in
+ * {@link http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf#page=44 Rijndael-ammended.pdf#page=44}:
+ * Extensions: Other block and Cipher Key lengths.
+ * Note: Use of 160/224-bit Keys must be explicitly set by setKeyLength(160) respectively setKeyLength(224).
+ *
+ * {@internal The variable names are the same as those in
+ * {@link http://www.csrc.nist.gov/publications/fips/fips197/fips-197.pdf#page=10 fips-197.pdf#page=10}.}}

+/**
+ * Pure-PHP implementation of SFTP.
+ *
+ * PHP version 5
+ *
+ * Currently only supports SFTPv2 and v3, which, according to wikipedia.org, "is the most widely used version,
+ * implemented by the popular OpenSSH SFTP server".  If you want SFTPv4/5/6 support, provide me with access
+ * to an SFTPv4/5/6 server.
+ *
+ * The API for this library is modeled after the API from PHP's {@link http://php.net/book.ftp FTP extension}.
+ *
+ * Here's a short example of how to use this library:
+ * <code>
+ * <?php
+ *    include 'vendor/autoload.php';
+ *
+ *    $sftp = new \phpseclib\Net\SFTP('www.domain.tld');
+ *    if (!$sftp->login('username', 'password')) {
+ *        exit('Login Failed');
+ *    }
+ *
+ *    echo $sftp->pwd() . "\r\n";
+ *    $sftp->put('filename.ext', 'hello, world!');
+ *    print_r($sftp->nlist());
+ * ?>
+ * </code>

+
+         "If the client wishes to interoperate with servers that support noncontiguous version
+          numbers it SHOULD send '3'"
+
+         Given that the server only sends its version number after the client has already done so, the above
+         seems to be suggesting that v3 should be the default version.  This makes sense given that v3 is the
+         most popular.
+
+         <http://tools.ietf.org/html/draft-ietf-secsh-filexfer-13#section-5.5> states the following;
+
+         "If the server did not send the "versions" extension, or the version-from-list was not included, the
+          server MAY send a status response describing the failure, but MUST then close the channel without
+          processing any further requests."
+
+         So what do you do if you have a client whose initial SSH_FXP_INIT packet says it implements v3 and
+         a server whose initial SSH_FXP_VERSION reply says it implements v4 and only v4?  If it only implements
+         v4, the "versions" extension is likely not going to have been sent so version re-negotiation as discussed
+         in draft-ietf-secsh-filexfer-13 would be quite impossible.  As such, what \phpseclib\Net\SFTP would do is close the
+         channel and reopen it with a new and updated SSH_FXP_INIT packet.

+     *
+     * By default, \phpseclib\Net\SFTP::put() does not read from the local filesystem.  $data is dumped directly into $remote_file.
+     * So, for example, if you set $data to 'filename.ext' and then do \phpseclib\Net\SFTP::get(), you will get a file, twelve bytes
+     * long, containing 'filename.ext' as its contents.
+     *
+     * Setting $mode to self::SOURCE_LOCAL_FILE will change the above behavior.  With self::SOURCE_LOCAL_FILE, $remote_file will
+     * contain as many bytes as filename.ext does on your local filesystem.  If your filename.ext is 1MB then that is how
+     * large $remote_file will be, as well.
+     *
+     * Setting $mode to self::SOURCE_CALLBACK will use $data as callback function, which gets only one parameter -- number of bytes to return, and returns a string if there is some data or null if there is no more data
+     *
+     * If $data is a resource then it'll be used as a resource instead.
+     *
+     * Currently, only binary mode is supported.  As such, if the line endings need to be adjusted, you will need to take
+     * care of that, yourself.
+     *
+     * $mode can take an additional two parameters - self::RESUME and self::RESUME_START. These are bitwise AND'd with
+     * $mode. So if you want to resume upload of a 300mb file on the local file system you'd set $mode to the following:
+     *
+     * self::SOURCE_LOCAL_FILE | self::RESUME
+     *
+     * If you wanted to simply append the full contents of a local file to the full contents of a remote file you'd replace
+     * self::RESUME with self::RESUME_START.
+     *
+     * If $mode & (self::RESUME | self::RESUME_START) then self::RESUME_START will be assumed.
+     *
+     * $start and $local_start give you more fine grained control over this process and take precident over self::RESUME
+     * when they're non-negative. ie. $start could let you write at the end of a file (like self::RESUME) or in the middle
+     * of one. $local_start could let you start your reading from the end of a file (like self::RESUME_START) or in the
+     * middle of one.
+     *

+Plugin for testing ad layout
+
+This plugin uses the UAPPlugin framework to output ad content. However,
+its ad content is just images with one red pixel stretched to the
+right size. It's mostly useful for debugging theme layout.
+
+To use this plugin, set the parameter for the ad size you want to use
+to true (or anything non-null).
+
+Example
+=======
+To make a leaderboard:
+
+addPlugin('BlankAd', array('leaderboard' => true));

-Facebook Bridge Plugin
-
-The Facebook Bridge plugin allows you to integrate your StatusNet site
-with Facebook. It uses Facebook's new SDKs, the Graph API and OAuth
-2.0, and supercedes the previous "Facebook" plugin, which relied on the
-Facebook's now deprecated "Old REST API". The other major difference is
-the troublesome and confusing Facebook Canvas Application has been
-removed.
-
-Note: Do NOT try to run the old Facebook plugin and this plugin at the same
-time. It won't work.
-
-Features for the new Facebook Bridge Plugin:
-
-- "Login with Facebook" (AKA single-sign-on using Facebook Connect for
-  authentication).
-
-- Registration with Facebook Connect, including automatic profile creation
-  based on users' Facebook accounts.
-
-- Post mirroring -- posting a notice on StatusNet automatically creates a post
-  on Facebook, deleting it on StatusNet deletes it on Facebook, and faving it
-  "likes" it on Facebook.
-
-
-Upgrading from the old Facebook plugin
-======================================
-
-Remove the addPlugin('Facebook') statement for the old Facebook plugin
-from your config.php and adjust your existing Facebook application using
-the setup instructions below as a guide, then enable the new plugin (also
-described below). Existing users who have setup post mirroring shouldn't
-have to do anything. The new Facebook Bridge plugin will keep their notices
-flowing to Facebook.
-
-Setup
-=====
-
-There are two parts configuring the Facebook Bridge plugin -- setup on the
-Facebook side, and setup on the StatusNet side.
-
-Setup (Facebook side)
-=====================
-
-The first step is to login to Facebook and register a Facebook application
-to get an application ID and secret.
-
-Use the handy Facebook application setup wizard:
-
-http://developers.facebook.com/setup/
-
-Once you've set up your application, you'll need to enter the Facebook Developer
-dashboard (http://www.facebook.com/developers/editapp.php?app_id=YOUR_APPLICATION_ID)
-and customize a few things:
-
-About tab
----------
-
-Set your logos, application description, etc. as you see fit.
-
-Web Site tab
-------------
-
-Make a note of the "Application ID" and "Application Secret" Facebook generated
-for your application. You'll need both of those later.
-
-Make sure "Site URL" points to your StatusNet installation
-(e.g.: http://example.net/).
-
-- Special Note for multi-site Status Networks: enter your domain (SLD and TLD)
-  in the "Site Domain" field. (e.g.: status.net). This will allow a single
-  Facebook Application to work with all your network subdomains (*.status.net).
-
-Facebook Integration tab
-------------------------
-
-Use the default settings.
-
-Mobile and Devices tab
-----------------------
-
-Use the default settings.
-
-Advanced tab
-------------
-
-In the Authentication section, set the "Deauthorize Callback" to
-http://YOURSITE/facebook/deauthorize (e.g.: http://example.net/facebook/deauthorize).
-
-In the Migrations section, ensure that "OAuth 2.0 for Canvas" is set to
-"Enabled". It probably already will be, but double check.
-
-The default settings should suffice for everything else.
-
-Setup (StatusNet side)
-======================
-
-To enable the Facebook Bridge plugin, add
-
-    addPlugin('FacebookBridge');
-
-to you config.php.
-
-Next login to your StatusNet site as a user with the administrator role, and
-navigate to the admin menu. You should see a new tab for the Facebook admin
-panel, titled "Facebook".  Enter your Facebook application ID and secret in
-that admin panel and hit save. After that, the Facebook Bridge Plugin should
-be ready to use.

+Settings
+========
+servers: Array of memcache servers addresses
+defaultExpiry: How long before cache expires (in seconds)
+compressThreshold: Items over this size threshold are eligible for compression (in bytes)
+compressMinSaving: If the compression would save more than this ratio, items are eligible for compression

-The Minify plugin minifies your CSS and Javascript, removing whitespace and
-comments.
-
-Note that if enabled this plugin and use a theme server,
-    (if any of $config['theme']['server'], $config['theme']['path'],
-    $config['theme']['dir'] are set) theme CSS will not be minified.
-
-This plugin will use memcache, if it is available, for storing minified inline
-    and file javascript and css. Because minification is non-trivial, using
-    memcache is recommended.
-
-Installation
-============
-add "addPlugin('minify',
-    array('setting'=>'value', 'setting2'=>'value2', ...);"
-to the bottom of your config.php
-
-Settings
-========
-minifyInlineJs (true): Minify inline javascript.
-    Because caching isn'tas effective for inline resources (due to its more
-    dynamic nature) than static files, minifying inline resources may adversely
-    affect performance for higher volume sites. Testing (and memcache usage)
-    are highly recommended.
-minifyInlineCss (true): Minify inline CSS.
-    Because caching isn'tas effective for inline resources (due to its more

-    affect performance for higher volume sites. Testing (and memcache usage)

-WELCOME TO MINIFY 2.1!
-
-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.
-
-
-UPGRADING
-
-See UPGRADING.txt for instructions.
-
-
-INSTALLATION AND USAGE:
-
-1. Place the /min/ directory as a child of your DOCUMENT_ROOT
-directory: i.e. you will have: /home/user/www/public_html/min
-
-2. Open http://yourdomain/min/ in a web browser. This will forward
-you to the Minify URI Builder application, which will help you
-quickly start using Minify to serve content on your site.
-
-
-UNIT TESTING:
-
-1. Place the /min_unit_tests/ directory as a child of your DOCUMENT_ROOT
-directory: i.e. you will have: /home/user/www/public_html/min_unit_tests
-
-2. To run unit tests, access: http://yourdomain/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.
-
-
-EXTRAS:
-
-The min_extras folder contains files for benchmarking using Apache ab on Windows
-and a couple single-use tools. DO NOT place this on your production server.
-
-
-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.

-Minify Upgrade Guide
-
-UPGRADING FROM 2.1.*
-
-1. Rename the following files:
-
-    /min/config.php       --> /min/old_config.php
-    /min/groupsConfig.php --> /min/old_groupsConfig.php
-
-2. Overwrite all files in /min (and /min_unit_tests) with those from this zip.
-
-3. Delete /min/groupsConfig.php
-
-4. Rename /min/old_groupsConfig.php --> /min/groupsConfig.php
-
-5. Merge your settings in old_config.php into config.php.
-
-    * If you've set $_SERVER['DOCUMENT_ROOT'], instead set the new option
-      $min_documentRoot. This is advantageous on IIS systems because Minify
-      will no longer overwrite the path you specified.
-
-    * $min_errorLogger adds the ability to enable FirePHP logging.
-
-6. (optional) Delete /min/old_config.php and the Minify files from your cache
-   directory (specified in $min_cachePath).
-
-
-INSTALLING FRESH
-
-See README.txt for instructions on installing this app for the first time.

-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.

->may reduce the benefit of proxy cache servers</a>.</p>

-<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>
-</div>
-
-<div id=getBm>
-<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!

-     * Serve a request for a minified file.

-     * Here are the available options and defaults in the base controller:
-     *
-     * 'isPublic' : send "public" instead of "private" in Cache-Control
-     * headers, allowing shared caches to cache the output. (default true)
-     *
-     * '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
-     * controller. E.g. 'Files'
-     *
-     * @param array $options controller/serve options
-     *
-     * @return mixed null, or, if the 'quiet' option is set to true, an array

- *
- * PHP versions 4 and 5
- *
- * If {@link Crypt_AES::setKeyLength() setKeyLength()} isn't called, it'll be calculated from
- * {@link Crypt_AES::setKey() setKey()}.  ie. if the key is 128-bits, the key length will be 128-bits.  If it's 136-bits

- *
- * Since Crypt_AES extends Crypt_Rijndael, some functions are available to be called that, in the context of AES, don't
- * make a whole lot of sense.  {@link Crypt_AES::setBlockLength() setBlockLength()}, for instance.  Calling that function,
- * however possible, won't do anything (AES has a fixed block length whereas Rijndael has a variable one).

- *
- *    $aes = new Crypt_AES();
- *

- * Pure-PHP implementation of RC4.

- * <code>
- * <?php
- *    include('Crypt/RC4.php');
- *
- *    $rc4 = new Crypt_RC4();
- *
- *    $rc4->setKey('abcdefgh');

-     * public key should have the second byte set to 2.  In RFC3447 (PKCS#1 v2.1), the second byte is supposed
-     * to be 2 regardless of which key is used.  For compatability purposes, we'll just check to make sure the
-     * second byte is 2 or less.  If it is, we'll accept the decrypted string as valid.
-     *
-     * As a consequence of this, a private key encrypted ciphertext produced with Crypt_RSA may not decrypt
-     * with a strictly PKCS#1 v1.5 compliant RSA implementation.  Public key encrypted ciphertext's should but

- * Pure-PHP implementation of Rijndael.
- *
- * Uses mcrypt, if available/possible, and an internal implementation, otherwise.
- *
- * PHP versions 4 and 5
- *
- * If {@link Crypt_Rijndael::setBlockLength() setBlockLength()} isn't called, it'll be assumed to be 128 bits.  If
- * {@link Crypt_Rijndael::setKeyLength() setKeyLength()} isn't called, it'll be calculated from
- * {@link Crypt_Rijndael::setKey() setKey()}.  ie. if the key is 128-bits, the key length will be 128-bits.  If it's
- * 136-bits it'll be null-padded to 192-bits and 192 bits will be the key length until
- * {@link Crypt_Rijndael::setKey() setKey()} is called, again, at which point, it'll be recalculated.
- *
- * Not all Rijndael implementations may support 160-bits or 224-bits as the block length / key length.  mcrypt, for example,
- * does not.  AES, itself, only supports block lengths of 128 and key lengths of 128, 192, and 256.
- * {@link http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf#page=10 Rijndael-ammended.pdf#page=10} defines the
- * algorithm for block lengths of 192 and 256 but not for block lengths / key lengths of 160 and 224.  Indeed, 160 and 224
- * are first defined as valid key / block lengths in
- * {@link http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf#page=44 Rijndael-ammended.pdf#page=44}:
- * Extensions: Other block and Cipher Key lengths.
- * Note: Use of 160/224-bit Keys must be explicitly set by setKeyLength(160) respectively setKeyLength(224).
- *
- * {@internal The variable names are the same as those in
- * {@link http://www.csrc.nist.gov/publications/fips/fips197/fips-197.pdf#page=10 fips-197.pdf#page=10}.}}

+                    GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<http://www.gnu.org/licenses/>.

+# "Sensitive" Content Plugin for GNU Social
+
+## About
+
+WARNING: THIS IS ALPHA CODE, IT IS PRERELEASE AND SHOULD ONLY BE INSTALLED TO
+HELP TEST OR YOU ARE WILLING TO TAKE RISKS.
+
+Create user option to allow a user to hide #NSFW-hashtagged notices behind a
+blocker image until clicked.
+
+Works for both vanilla GNUSocial and with the Qvitter plugin.
+
+## Install
+
+- Move the project directory to ${GNU_SOCIAL}/plugins
+- Add addPlugin('SensitiveContent'); to your config.php
+
+if you want to customize the blocker image, add a line to your config.php:
+
+  $config['site']['sensitivecontent']['blockerimage'] = "/path/to/image.jpg";
+
+## Usage
+
+Individual users must go to their Settings page. A new sidebar menu item "Sensitive Content"
+will be available. User checks or unchecks the checkbox on this page, and presses save.
+
+
+If you have GNU Social open in other browser tabs, refresh them. If you are using Qvitter, also
+refresh, but because Qvitter caches notices on the client side, only new sensitive images will
+be hidden, it will not apply to notices retroactively unless you clear your browser cache.
+
+## License
+
+GNU Affero License
+
+## Thanks
+
+Thanks in particular to Hannes and Qvitter because looking at his code helped me a lot.
+
+A tiny bit of content was taken from Qvitter to enhance Qvitter with this functionality.
