+
+PHP Markdown Extra
+==================
+
+Description
+-----------
+
+This is a PHP port of the original Markdown formatter written in Perl
+by John Gruber. This special "Extra" version of PHP Markdown features
+further enhancements to the syntax for making additional constructs
+such as tables and definition list.
+
+Markdown is a text-to-HTML filter; it translates an easy-to-read /
+easy-to-write structured text format into HTML. Markdown's text format
+is most similar to that of plain text email, and supports features such
+as headers, *emphasis*, code blocks, blockquotes, and links.
+
+Markdown's syntax is designed not as a generic markup language, but
+specifically to serve as a front-end to (X)HTML. You can use span-level
+HTML tags anywhere in a Markdown document, and you can use block level
+HTML tags (like and as well).
+
+For more information about Markdown's syntax, see:
+
+
+
+
+Bugs
+----
+
+To file bug reports please send email to:
+
+
+
+Please include with your report: (1) the example input; (2) the output you
+expected; (3) the output Markdown actually produced.

-PHP Markdown Extra
-==================
-
-Description
------------
-
-This is a PHP port of the original Markdown formatter written in Perl
-by John Gruber. This special "Extra" version of PHP Markdown features
-further enhancements to the syntax for making additional constructs
-such as tables and definition list.
-
-Markdown is a text-to-HTML filter; it translates an easy-to-read /
-easy-to-write structured text format into HTML. Markdown's text format
-is most similar to that of plain text email, and supports features such
-as headers, *emphasis*, code blocks, blockquotes, and links.
-
-Markdown's syntax is designed not as a generic markup language, but
-specifically to serve as a front-end to (X)HTML. You can use span-level
-HTML tags anywhere in a Markdown document, and you can use block level
-HTML tags (like and as well).
-
-For more information about Markdown's syntax, see:

+PHP Markdown
+============
+
+PHP Markdown Lib 1.7.0 - 29 Oct 2016
+
+by Michel Fortin
+
+
+based on Markdown by John Gruber
+
+
+
+Introduction
+------------
+
+This is a library package that includes the PHP Markdown parser and its
+sibling PHP Markdown Extra with additional features.
+
+Markdown is a text-to-HTML conversion tool for web writers. Markdown
+allows you to write using an easy-to-read, easy-to-write plain text
+format, then convert it to structurally valid XHTML (or HTML).
+
+"Markdown" is actually two things: a plain text markup syntax, and a
+software tool, originally written in Perl, that converts the plain text
+markup to HTML. PHP Markdown is a port to PHP of the original Markdown
+program by John Gruber.
+
+* [Full documentation of the Markdown syntax]( )
+ — Daring Fireball (John Gruber)
+* [Markdown Extra syntax additions]( )
+ — Michel Fortin
+
+
+Requirement
+-----------
+
+This library package requires PHP 5.3 or later.
+
+Note: The older plugin/library hybrid package for PHP Markdown and
+PHP Markdown Extra is still maintained and will work with PHP 4.0.5 and later.
+
+Before PHP 5.3.7, pcre.backtrack_limit defaults to 100 000, which is too small
+in many situations. You might need to set it to higher values. Later PHP
+releases defaults to 1 000 000, which is usually fine.
+
+
+Usage
+-----
+
+This library package is meant to be used with class autoloading. For autoloading
+to work, your project needs have setup a PSR-0-compatible autoloader. See the
+included Readme.php file for a minimal autoloader setup. (If you cannot use
+autoloading, see below.)
+
+With class autoloading in place, putting the 'Michelf' folder in your
+include path should be enough for this to work:
+
+ use \Michelf\Markdown;
+ $my_html = Markdown::defaultTransform($my_text);
+
+Markdown Extra syntax is also available the same way:
+
+ use \Michelf\MarkdownExtra;
+ $my_html = MarkdownExtra::defaultTransform($my_text);
+
+If you wish to use PHP Markdown with another text filter function
+built to parse HTML, you should filter the text *after* the `transform`
+function call. This is an example with [PHP SmartyPants][psp]:
+
+ use \Michelf\Markdown, \Michelf\SmartyPants;
+ $my_html = Markdown::defaultTransform($my_text);
+ $my_html = SmartyPants::defaultTransform($my_html);
+
+All these examples are using the static `defaultTransform` static function
+found inside the parser class. If you want to customize the parser
+configuration, you can also instantiate it directly and change some
+configuration variables:
+
+ use \Michelf\MarkdownExtra;
+ $parser = new MarkdownExtra;
+ $parser->fn_id_prefix = "post22-";
+ $my_html = $parser->transform($my_text);
+
+To learn more, see the full list of [configuration variables].
+
+ [configuration variables]: https://michelf.ca/projects/php-markdown/configuration/
+
+
+### Usage without an autoloader
+
+If you cannot use class autoloading, you can still use `include` or `require`
+to access the parser. To load the `\Michelf\Markdown` parser, do it this way:
+
+ require_once 'Michelf/Markdown.inc.php';
+
+Or, if you need the `\Michelf\MarkdownExtra` parser:
+
+ require_once 'Michelf/MarkdownExtra.inc.php';
+
+While the plain `.php` files depend on autoloading to work correctly, using the
+`.inc.php` files instead will eagerly load the dependencies that would be
+loaded on demand if you were using autoloading.
+
+
+Public API and Versioning Policy
+---------------------------------
+
+Version numbers are of the form *major*.*minor*.*patch*.
+
+The public API of PHP Markdown consist of the two parser classes `Markdown`
+and `MarkdownExtra`, their constructors, the `transform` and `defaultTransform`
+functions and their configuration variables. The public API is stable for
+a given major version number. It might get additions when the minor version
+number increments.
+
+**Protected members are not considered public API.** This is unconventional
+and deserves an explanation. Incrementing the major version number every time
+the underlying implementation of something changes is going to give
+nonessential version numbers for the vast majority of people who just use the
+parser. Protected members are meant to create parser subclasses that behave in
+different ways. Very few people create parser subclasses. I don't want to
+discourage it by making everything private, but at the same time I can't
+guarantee any stable hook between versions if you use protected members.
+
+**Syntax changes** will increment the minor number for new features, and the
+patch number for small corrections. A *new feature* is something that needs a
+change in the syntax documentation. Note that since PHP Markdown Lib includes
+two parsers, a syntax change for either of them will increment the minor
+number. Also note that there is nothing perfectly backward-compatible with the
+Markdown syntax: all inputs are always valid, so new features always replace
+something that was previously legal, although generally nonsensical to do.
+
+
+Bugs
+----
+
+To file bug reports please send email to:
+
+
+Please include with your report: (1) the example input; (2) the output you
+expected; (3) the output PHP Markdown actually produced.
+
+If you have a problem where Markdown gives you an empty result, first check
+that the backtrack limit is not too low by running `php --info | grep pcre`.
+See Installation and Requirement above for details.
+
+
+Development and Testing
+-----------------------
+
+Pull requests for fixing bugs are welcome. Proposed new features are
+going to be meticulously reviewed -- taking into account backward compatibility,
+potential side effects, and future extensibility -- before deciding on
+acceptance or rejection.
+
+If you make a pull request that includes changes to the parser please add
+tests for what is being changed to [MDTest][] and make a pull request there
+too.

+
+Version History
+---------------
+
+PHP Markdown Lib 1.7.0 (29 Oct 2016)
+
+* Added a `hard_wrap` configuration variable to make all newline characters
+ in the text become `
` tags in the HTML output. By default, according
+ to the standard Markdown syntax these newlines are ignored unless they a
+ preceded by two spaces. Thanks to Jonathan Cohlmeyer for the implementation.
+
+* Improved the parsing of list items to fix problematic cases that came to
+ light with the addition of `hard_wrap`. This should have no effect on the
+ output except span-level list items that ended with two spaces (and thus
+ ended with a line break).
+
+* Added a `code_span_content_func` configuration variable which takes a
+ function that will convert the content of the code span to HTML. This can
+ be useful to implement syntax highlighting. Although contrary to its
+ code block equivalent, there is no syntax for specifying a language.
+ Credits to styxit for the implementation.
+
+* Fixed a Markdwon Extra issue where two-space-at-end-of-line hard breaks
+ wouldn't work inside of HTML block elements such as ``
+ where the element expects only span-level content.
+
+* In the parser code, switched to PHPDoc comment format. Thanks to
+ Robbie Averill for the help.
+
+
+PHP Markdown Lib 1.6.0 (23 Dec 2015)
+
+Note: this version was incorrectly released as 1.5.1 on Dec 22, a number
+that contradicted the versioning policy.
+
+* For fenced code blocks in Markdown Extra, can now set a class name for the
+ code block's language before the special attribute block. Previously, this
+ class name was only allowed in the absence of the special attribute block.
+
+* Added a `code_block_content_func` configuration variable which takes a
+ function that will convert the content of the code block to HTML. This is
+ most useful for syntax highlighting. For fenced code blocks in Markdown
+ Extra, the function has access to the language class name (the one outside
+ of the special attribute block). Credits to Mario Konrad for providing the
+ implementation.
+
+* The curled arrow character for the backlink in footnotes is now followed
+ by a Unicode variant selector to prevent it from being displayed in emoji
+ form on iOS.
+
+ Note that in older browsers the variant selector is often interpreted as a
+ separate character, making it visible after the arrow. So there is now a
+ also a `fn_backlink_html` configuration variable that can be used to set
+ the link text to something else. Credits to Dana for providing the
+ implementation.
+
+* Fixed an issue in MarkdownExtra where long header lines followed by a
+ special attribute block would hit the backtrack limit an cause an empty
+ string to be returned.
+
+
+PHP Markdown Lib 1.5.0 (1 Mar 2015)
+
+* Added the ability start ordered lists with a number different from 1 and
+ and have that reflected in the HTML output. This can be enabled with
+ the `enhanced_ordered_lists` configuration variable for the Markdown
+ parser; it is enabled by default for Markdown Extra.
+ Credits to Matt Gorle for providing the implementation.
+
+* Added the ability to insert custom HTML attributes with simple values
+ everywhere an extra attribute block is allowed (links, images, headers).
+ The value must be unquoted, cannot contains spaces and is limited to
+ alphanumeric ASCII characters.
+ Credits to Peter Droogmans for providing the implementation.
+
+* Added a `header_id_func` configuration variable which takes a function
+ that can generate an `id` attribute value from the header text.
+ Credits to Evert Pot for providing the implementation.
+
+* Added a `url_filter_func` configuration variable which takes a function
+ that can rewrite any link or image URL to something different.
+
+
+PHP Markdown Lib 1.4.1 (4 May 2014)
+
+* The HTML block parser will now treat `` as a block-level element
+ (as it should) and no longer wrap it in `` or parse it's content with
+ the as Markdown syntax (although with Extra you can use `markdown="1"`
+ if you wish to use the Markdown syntax inside it).
+
+* The content of ` Some text';
+
+ $config = HTMLPurifier_Config::createDefault();
+ $config->set('Filter', 'ExtractStyleBlocks', true);
+ $purifier = new HTMLPurifier($config);
+
+ $html = $purifier->purify($dirty);
+
+ // This implementation writes the stylesheets to the styles/ directory.
+ // You can also echo the styles inside the document, but it's a bit
+ // more difficult to make sure they get interpreted properly by
+ // browsers; try the usual CSS armoring techniques.
+ $styles = $purifier->context->get('StyleBlocks');
+ $dir = 'styles/';
+ if (!is_dir($dir)) mkdir($dir);
+ $hash = sha1($_GET['html']);
+ foreach ($styles as $i => $style) {
+ file_put_contents($name = $dir . $hash . "_$i");
+ echo '';
+ }

+
+]]>
+
+ Warning: It is possible for a user to mount an
+ imagecrash attack using this CSS. Counter-measures are difficult;
+ it is not simply enough to limit the range of CSS lengths (using
+ relative lengths with many nesting levels allows for large values
+ to be attained without actually specifying them in the stylesheet),
+ and the flexible nature of selectors makes it difficult to selectively
+ disable lengths on image tags (HTML Purifier, however, does disable
+ CSS width and height in inline styling). There are probably two effective
+ counter measures: an explicit width and height set to auto in all
+ images in your document (unlikely) or the disabling of width and
+ height (somewhat reasonable). Whether or not these measures should be
+ used is left to the reader.

+ If you attempt to allow an element that HTML Purifier does not know

+ Warning: If another directive conflicts with the

+
+
+ Unique identifier for a custom-built HTML definition. If you edit

+ If you change your custom edits, you should change this directive, or

+
+
+ In the above example, the configuration is still at the defaults, but
+ using the advanced API, an extra attribute has been added. The
+ configuration object normally has no way of knowing that this change
+ has taken place, so it needs an extra directive: %HTML.DefinitionID.
+ If someone else attempts to use the default configuration, these two
+ pieces of code will not clobber each other in the cache, since one has
+ an extra directive attached to it.
+
+
+ You must specify a value to this directive to use the
+ advanced API features.

+URI.Munge
+TYPE: string/null
+VERSION: 1.3.0
+DEFAULT: NULL
+--DESCRIPTION--
+
+
+ Munges all browsable (usually http, https and ftp)
+ absolute URIs into another URI, usually a URI redirection service.
+ This directive accepts a URI, formatted with a %s
where
+ the url-encoded original URI should be inserted (sample:
+ http://www.google.com/url?q=%s
).
+
+
+ Uses for this directive:
+
+
+ -
+ Prevent PageRank leaks, while being fairly transparent
+ to users (you may also want to add some client side JavaScript to
+ override the text in the statusbar). Notice:
+ Many security experts believe that this form of protection does not deter spam-bots.
+
+ -
+ Redirect users to a splash page telling them they are leaving your
+ website. While this is poor usability practice, it is often mandated
+ in corporate environments.
+
+
+
+ Prior to HTML Purifier 3.1.1, this directive also enabled the munging
+ of browsable external resources, which could break things if your redirection
+ script was a splash page or used meta
tags. To revert to
+ previous behavior, please use %URI.MungeResources.
+
+
+ You may want to also use %URI.MungeSecretKey along with this directive
+ in order to enforce what URIs your redirector script allows. Open
+ redirector scripts can be a security risk and negatively affect the
+ reputation of your domain name.
+
+
+ Starting with HTML Purifier 3.1.1, there is also these substitutions:
+
+
+
+
+ Key
+ Description
+ Example <a href="">
+
+
+
+
+ %r
+ 1 - The URI embeds a resource
(blank) - The URI is merely a link
+
+
+
+ %n
+ The name of the tag this URI came from
+ a
+
+
+ %m
+ The name of the attribute this URI came from
+ href
+
+
+ %p
+ The name of the CSS property this URI came from, or blank if irrelevant
+
+
+
+
+
+ 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 ****.
+//
+// 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
+// **** 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 , after you removed the , you
+// really would like this injector to go back and reprocess
+// the 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
+// to , 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.

+
+MODx Plugin
+
+MODx is an open source PHP application framework.
+I first came across them in my referrer logs when tillda asked if anyone
+could implement an HTML Purifier plugin. This forum thread
+ eventually resulted
+in the fruition of this plugin that davidm says, "is on top of my favorite
+list." HTML Purifier goes great with WYSIWYG editors!
+
+
+
+1. Credits
+
+PaulGregory wrote the overall structure of the code. I added the
+slashes hack.
+
+
+
+2. Install
+
+First, you need to place HTML Purifier library somewhere. The code here
+assumes that you've placed in MODx's assets/plugins/htmlpurifier (no version
+number).
+
+Log into the manager, and navigate:
+
+Resources > Manage Resources > Plugins tab > New Plugin
+
+Type in a name (probably HTML Purifier), and copy paste this code into the
+textarea:
+
+--------------------------------------------------------------------------------
+$e = &$modx->Event;
+if ($e->name == 'OnBeforeDocFormSave') {
+ global $content;
+
+ include_once '../assets/plugins/htmlpurifier/library/HTMLPurifier.auto.php';
+ $purifier = new HTMLPurifier();
+
+ static $magic_quotes = null;
+ if ($magic_quotes === null) {
+ // this is an ugly hack because this hook hasn't
+ // had the backslashes removed yet when magic_quotes_gpc is on,
+ // but HTMLPurifier must not have the quotes slashed.
+ $magic_quotes = get_magic_quotes_gpc();
+ }
+
+ if ($magic_quotes) $content = stripslashes($content);
+ $content = $purifier->purify($content);
+ if ($magic_quotes) $content = addslashes($content);
+}
+--------------------------------------------------------------------------------
+
+Then navigate to the System Events tab and check "OnBeforeDocFormSave".
+Save the plugin. HTML Purifier now is integrated!
+
+
+
+3. Making sure it works
+
+You can test HTML Purifier by deliberately putting in crappy HTML and seeing
+whether or not it gets fixed. A better way is to put in something like this:
+
+Il est bon
+
+...and seeing whether or not the content comes out as:
+
+Il est bon
+
+(lang to xml:lang synchronization is one of the many features HTML Purifier
+has).
+
+
+
+4. Caveat Emptor
+
+This code does not intercept save requests from the QuickEdit plugin, this may
+be added in a later version. It also modifies things on save, so there's a
+slight chance that HTML Purifier may make a boo-boo and accidently mess things
+up (the original version is not saved).
+
+Finally, make sure that MODx is using UTF-8. If you are using, say, a French
+localisation, you may be using Latin-1, if that's the case, configure
+HTML Purifier properly like this:
+
+$config = HTMLPurifier_Config::createDefault();
+$config->set('Core', 'Encoding', 'ISO-8859-1'); // or whatever encoding
+$purifier = new HTMLPurifier($config);
+
+
+
+5. Known Bugs
+
+'rn' characters sometimes mysteriously appear after purification. We are
+currently investigating this issue. See:
+
+
+
+6. See Also
+
+A modified version of Jot 1.1.3 is available, which integrates with HTML
+Purifier. You can check it out here:

+
+Install
+ How to install the Phorum HTML Purifier plugin
+
+0. PREREQUISITES
+----------------
+This Phorum module only works on PHP5 and with HTML Purifier 4.0.0
+or later.
+
+1. UNZIP
+--------
+Unzip phorum-htmlpurifier-x.y.z, producing an htmlpurifier folder.
+You've already done this step if you're reading this!
+
+2. MOVE
+-------
+Move the htmlpurifier folder to the mods/ folder of your Phorum
+installation, so the directory structure looks like:
+
+phorum/
+ mods/
+ htmlpurifier/
+ INSTALL - this install file
+ info.txt, ... - the module files
+ htmlpurifier/
+
+3. INSTALL HTML PURIFIER
+------------------------
+Download and unzip HTML Purifier . Place the contents of
+the library/ folder in the htmlpurifier/htmlpurifier folder. Your directory
+structure will look like:
+
+phorum/
+ mods/
+ htmlpurifier/
+ htmlpurifier/
+ HTMLPurifier.auto.php
+ ... - other files
+ HTMLPurifier/
+
+Advanced users:
+ If you have HTML Purifier installed elsewhere on your server,
+ all you need is an HTMLPurifier.auto.php file in the library folder which
+ includes the HTMLPurifier.auto.php file in your install.
+
+4. MIGRATE
+----------
+If you're setting up a new Phorum installation, all you need to do is create
+a blank migrate.php file in the htmlpurifier module folder (NOT the library
+folder.
+
+If you have an old Phorum installation and was using BBCode,
+copy migrate.bbcode.php to migrate.php. If you were using a different input
+format, follow the instructions in migrate.bbcode.php to create your own custom
+migrate.php file.
+
+Your directory structure should now look like this:
+
+phorum/
+ mods/
+ htmlpurifier/
+ migrate.php
+
+5. ENABLE
+---------
+Navigate to your Phorum admin panel at http://example.com/phorum/admin.php,
+click on Global Settings > Modules, scroll to "HTML Purifier Phorum Mod" and
+turn it On.
+
+6. MIGRATE SIGNATURES
+---------------------
+If you're setting up a new Phorum installation, skip this step.
+
+If you allowed your users to make signatures, navigate to the module settings
+page of HTML Purifier (Global Settings > Modules > HTML Purifier Phorum Mod >
+Configure), type in "yes" in the "Confirm" box, and press "Migrate."
+
+ONLY DO THIS ONCE! BE SURE TO BACK UP YOUR DATABASE!
+
+7. CONFIGURE
+------------
+Configure using Edit settings. See that page for more information.

+
+HTML Purifier Phorum Mod - Filter your HTML the Standards-Compliant Way!
+
+This Phorum mod enables HTML posting on Phorum. Under normal circumstances,
+this would cause a huge security risk, but because we are running
+HTML through HTML Purifier, output is guaranteed to be XSS free and
+standards-compliant.
+
+This mod requires HTML input, and previous markup languages need to be
+converted accordingly. Thus, it is vital that you create a 'migrate.php'
+file that works with your installation. If you're using the built-in
+BBCode formatting, simply move migrate.bbcode.php to that place; for
+other markup languages, consult said file for instructions on how
+to adapt it to your needs.
+
+ -- NOTE -------------------------------------------------
+ You can also run this module in parallel with another
+ formatting module; this module attempts to place itself
+ at the end of the filtering chain. However, if any
+ previous modules produce insecure HTML (for instance,
+ a JavaScript email obfuscator) they will get cleaned.
+
+This module will not work if 'migrate.php' is not created, and an improperly
+made migration file may *CORRUPT* Phorum, so please take your time to
+do this correctly. It should go without saying to *BACKUP YOUR DATABASE*
+before attempting anything here. If no migration is necessary, you can
+simply create a blank migrate.php file. HTML Purifier is smart and will
+not re-migrate already processed messages. However, the original code
+is irretrievably lost (we may change this in the future.)
+
+This module will not automatically migrate user signatures, because this
+process may take a long time. After installing the HTML Purifier module and
+then configuring 'migrate.php', navigate to Settings and click 'Migrate
+Signatures' to migrate all user signatures to HTML.
+
+All of HTML Purifier's usual functions are configurable via the mod settings
+page. If you require custom configuration, create config.php file in
+the mod directory that edits a $config variable. Be sure, also, to
+set $PHORUM['mod_htmlpurifier']['wysiwyg'] to TRUE if you are using a
+WYSIWYG editor (you can do this through a common hook or the web
+configuration form).

Subject: :arrow_up: Update SimplePie library.
As a follow up to issue #699 update SimplePie from 1.2.1-dev (around
6years old) to current git master (1.4.4-dev). We use the master branch
until the next release because it contains our patch for enclosure
titles already. The other patches in the library from us can be done by
configuring the SimplePie object in our code instead.
Used composer to manage this library and use class autoloading.
Add some unit tests for include/feedutils.php, but the interesting parts
are unfortunately not testable with the current code.

+SimplePie
+=========
+
+SimplePie is a very fast and easy-to-use class, written in PHP, that puts the
+'simple' back into 'really simple syndication'. Flexible enough to suit
+beginners and veterans alike, SimplePie is focused on [speed, ease of use,
+compatibility and standards compliance][what_is].
+
+[what_is]: http://simplepie.org/wiki/faq/what_is_simplepie
+
+
+Requirements
+------------
+* PHP 5.3.0+ (5.3.6+ recommended since SimplePie 1.4.2)
+ * Support for PHP 5.2 stopped in branch `one-dot-three`
+ * Support for PHP 4 stopped in branch `one-dot-two`
+* libxml2 (certain 2.7.x releases are too buggy for words, and will crash)
+* One of iconv, mbstring or intl extensions
+* cURL or fsockopen()
+* PCRE support
+
+
+What comes in the package?
+--------------------------
+1. `library/` - SimplePie classes for use with the autoloader
+2. `autoloader.php` - The SimplePie Autoloader if you want to use the separate
+ file version.
+3. `README.markdown` - This document.
+4. `LICENSE.txt` - A copy of the BSD license.
+5. `compatibility_test/` - The SimplePie compatibility test that checks your
+ server for required settings.
+6. `demo/` - A basic feed reader demo that shows off some of SimplePie's more
+ noticeable features.
+7. `idn/` - A third-party library that SimplePie can optionally use to
+ understand Internationalized Domain Names (IDNs).
+8. `build/` - Scripts related to generating pieces of SimplePie
+9. `test/` - SimplePie's unit test suite.
+
+### Where's `simplepie.inc`?
+Since SimplePie 1.3, we've split the classes into separate files to make it easier
+to maintain and use.
+
+If you'd like a single monolithic file, you can run `php build/compile.php` to
+generate `SimplePie.compiled.php`.
+
+To start the demo
+-----------------
+1. Upload this package to your webserver.
+2. Make sure that the cache folder inside of the demo folder is server-writable.
+3. Navigate your browser to the demo folder.
+
+
+Need support?
+-------------
+For further setup and install documentation, function references, etc., visit
+[the wiki][wiki]. If you're using the latest version off GitHub, you can also
+check out the [API documentation][].
+
+If you can't find an answer to your question in the documentation, head on over

+
+Project status
+--------------
+SimplePie is currently maintained by Malcolm Blaney.
+
+As an open source project, SimplePie is maintained on a somewhat sporadic basis.
+This means that feature requests may not be fulfilled straight away, as time has
+to be prioritized.
+
+If you'd like to contribute to SimplePie, the best way to get started is to fork
+the project on GitHub and send pull requests for patches. When doing so, please
+be aware of our [coding standards][].

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+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 this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+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
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser 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 Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "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
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY 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
+LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+
+ Copyright (C)
+
+ This library is free software; you can redistribute it and/or
+ modify it under the terms of the GNU Lesser General Public
+ License as published by the Free Software Foundation; either
+ version 2.1 of the License, or (at your option) any later version.
+
+ This library is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of

+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:

+
+Introduction
+------------
+
+The class idna_convert allows to convert internationalized domain names
+(see RFC 3490, 3491, 3492 and 3454 for detials) as they can be used with various
+registries worldwide to be translated between their original (localized) form
+and their encoded form as it will be used in the DNS (Domain Name System).
+
+The class provides two public methods, encode() and decode(), which do exactly
+what you would expect them to do. You are allowed to use complete domain names,
+simple strings and complete email addresses as well. That means, that you might
+use any of the following notations:
+
+- www.nörgler.com
+- xn--nrgler-wxa
+- xn--brse-5qa.xn--knrz-1ra.info
+
+Errors, incorrectly encoded or invalid strings will lead to either a FALSE
+response (when in strict mode) or to only partially converted strings.
+You can query the occured error by calling the method get_last_error().
+
+Unicode strings are expected to be either UTF-8 strings, UCS-4 strings or UCS-4
+arrays. The default format is UTF-8. For setting different encodings, you can
+call the method setParams() - please see the inline documentation for details.
+ACE strings (the Punycode form) are always 7bit ASCII strings.
+
+ATTENTION: We no longer supply the PHP5 version of the class. It is not
+necessary for achieving a successfull conversion, since the supplied PHP code is
+compatible with both PHP4 and PHP5. We expect to see no compatibility issues
+with the upcoming PHP6, too.
+
+
+Files
+-----
+
+idna_convert.class.php - The actual class
+idna_convert.create.npdata.php - Useful for (re)creating the NPData file
+npdata.ser - Serialized data for NamePrep
+example.php - An example web page for converting
+ReadMe.txt - This file
+LICENCE - The LGPL licence file
+
+The class is contained in idna_convert.class.php.
+MAKE SURE to copy the npdata.ser file into the same folder as the class file
+itself!
+
+
+Examples
+--------
+
+1. Say we wish to encode the domain name nörgler.com:
+
+// Include the class
+include_once('idna_convert.class.php');
+// Instantiate it *
+$IDN = new idna_convert();
+// The input string, if input is not UTF-8 or UCS-4, it must be converted before
+$input = utf8_encode('nörgler.com');
+// Encode it to its punycode presentation
+$output = $IDN->encode($input);
+// Output, what we got now
+echo $output; // This will read: xn--nrgler-wxa.com
+
+
+2. We received an email from a punycoded domain and are willing to learn, how
+ the domain name reads originally
+
+// Include the class
+include_once('idna_convert.class.php');
+// Instantiate it (depending on the version you are using) with
+$IDN = new idna_convert();
+// The input string
+$input = 'andre@xn--brse-5qa.xn--knrz-1ra.info';
+// Encode it to its punycode presentation
+$output = $IDN->decode($input);
+// Output, what we got now, if output should be in a format different to UTF-8
+// or UCS-4, you will have to convert it before outputting it
+echo utf8_decode($output); // This will read: andre@börse.knörz.info
+
+
+3. The input is read from a UCS-4 coded file and encoded line by line. By
+ appending the optional second parameter we tell enode() about the input
+ format to be used
+
+// Include the class
+include_once('idna_convert.class.php');
+// Instantiate it
+$IDN = new dinca_convert();
+// Iterate through the input file line by line
+foreach (file('ucs4-domains.txt') as $line) {
+ echo $IDN->encode(trim($line), 'ucs4_string');
+ echo "\n";
+}
+
+
+NPData
+------
+
+Should you need to recreate the npdata.ser file, which holds all necessary translation
+tables in a serialized format, you can run the file idna_convert.create.npdata.php, which
+creates the file for you and stores it in the same folder, where it is placed.
+Should you need to do changes to the tables you can do so, but beware of the consequences.
