+ * association type to return to the consumer.

+/**
+ * This module documents the main interface with the OpenID consumer
+ * library. The only part of the library which has to be used and
+ * isn't documented in full here is the store required to create an
+ * Auth_OpenID_Consumer instance. More on the abstract store type and
+ * concrete implementations of it that are provided in the
+ * documentation for the Auth_OpenID_Consumer constructor.
+ *
+ * OVERVIEW
+ *
+ * The OpenID identity verification process most commonly uses the
+ * following steps, as visible to the user of this library:
+ *
+ * 1. The user enters their OpenID into a field on the consumer's
+ * site, and hits a login button.
+ * 2. The consumer site discovers the user's OpenID server using the
+ * YADIS protocol.
+ * 3. The consumer site sends the browser a redirect to the identity
+ * server. This is the authentication request as described in
+ * the OpenID specification.
+ * 4. The identity server's site sends the browser a redirect back
+ * to the consumer site. This redirect contains the server's
+ * response to the authentication request.
+ *
+ * The most important part of the flow to note is the consumer's site
+ * must handle two separate HTTP requests in order to perform the full
+ * identity check.
+ *
+ * LIBRARY DESIGN
+ *
+ * This consumer library is designed with that flow in mind. The goal
+ * is to make it as easy as possible to perform the above steps
+ * securely.
+ *
+ * At a high level, there are two important parts in the consumer
+ * library. The first important part is this module, which contains
+ * the interface to actually use this library. The second is the
+ * Auth_OpenID_Interface class, which describes the interface to use
+ * if you need to create a custom method for storing the state this
+ * library needs to maintain between requests.
+ *
+ * In general, the second part is less important for users of the
+ * library to know about, as several implementations are provided
+ * which cover a wide variety of situations in which consumers may use
+ * the library.
+ *
+ * This module contains a class, Auth_OpenID_Consumer, with methods
+ * corresponding to the actions necessary in each of steps 2, 3, and 4
+ * described in the overview. Use of this library should be as easy
+ * as creating an Auth_OpenID_Consumer instance and calling the
+ * methods appropriate for the action the site wants to take.
+ *
+ * STORES AND DUMB MODE
+ *
+ * OpenID is a protocol that works best when the consumer site is able
+ * to store some state. This is the normal mode of operation for the
+ * protocol, and is sometimes referred to as smart mode. There is
+ * also a fallback mode, known as dumb mode, which is available when
+ * the consumer site is not able to store state. This mode should be
+ * avoided when possible, as it leaves the implementation more
+ * vulnerable to replay attacks.
+ *
+ * The mode the library works in for normal operation is determined by
+ * the store that it is given. The store is an abstraction that
+ * handles the data that the consumer needs to manage between http
+ * requests in order to operate efficiently and securely.
+ *
+ * Several store implementation are provided, and the interface is
+ * fully documented so that custom stores can be used as well. See
+ * the documentation for the Auth_OpenID_Consumer class for more
+ * information on the interface for stores. The implementations that
+ * are provided allow the consumer site to store the necessary data in
+ * several different ways, including several SQL databases and normal
+ * files on disk.
+ *
+ * There is an additional concrete store provided that puts the system
+ * in dumb mode. This is not recommended, as it removes the library's
+ * ability to stop replay attacks reliably. It still uses time-based
+ * checking to make replay attacks only possible within a small
+ * window, but they remain possible within that window. This store
+ * should only be used if the consumer site has no way to retain data
+ * between requests at all.
+ *
+ * IMMEDIATE MODE
+ *
+ * In the flow described above, the user may need to confirm to the
+ * lidentity server that it's ok to authorize his or her identity.
+ * The server may draw pages asking for information from the user
+ * before it redirects the browser back to the consumer's site. This
+ * is generally transparent to the consumer site, so it is typically
+ * ignored as an implementation detail.
+ *
+ * There can be times, however, where the consumer site wants to get a
+ * response immediately. When this is the case, the consumer can put
+ * the library in immediate mode. In immediate mode, there is an
+ * extra response possible from the server, which is essentially the
+ * server reporting that it doesn't have enough information to answer
+ * the question yet.
+ *
+ * USING THIS LIBRARY
+ *
+ * Integrating this library into an application is usually a
+ * relatively straightforward process. The process should basically
+ * follow this plan:
+ *
+ * Add an OpenID login field somewhere on your site. When an OpenID
+ * is entered in that field and the form is submitted, it should make
+ * a request to the your site which includes that OpenID URL.
+ *
+ * First, the application should instantiate the Auth_OpenID_Consumer
+ * class using the store of choice (Auth_OpenID_FileStore or one of
+ * the SQL-based stores). If the application has a custom
+ * session-management implementation, an object implementing the
+ * {@link Auth_Yadis_PHPSession} interface should be passed as the
+ * second parameter. Otherwise, the default uses $_SESSION.
+ *
+ * Next, the application should call the Auth_OpenID_Consumer object's
+ * 'begin' method. This method takes the OpenID URL. The 'begin'
+ * method returns an Auth_OpenID_AuthRequest object.
+ *
+ * Next, the application should call the 'redirectURL' method of the
+ * Auth_OpenID_AuthRequest object. The 'return_to' URL parameter is
+ * the URL that the OpenID server will send the user back to after
+ * attempting to verify his or her identity. The 'trust_root' is the
+ * URL (or URL pattern) that identifies your web site to the user when
+ * he or she is authorizing it. Send a redirect to the resulting URL
+ * to the user's browser.
+ *
+ * That's the first half of the authentication process. The second
+ * half of the process is done after the user's ID server sends the
+ * user's browser a redirect back to your site to complete their
+ * login.
+ *
+ * When that happens, the user will contact your site at the URL given
+ * as the 'return_to' URL to the Auth_OpenID_AuthRequest::redirectURL
+ * call made above. The request will have several query parameters
+ * added to the URL by the identity server as the information
+ * necessary to finish the request.
+ *
+ * Lastly, instantiate an Auth_OpenID_Consumer instance as above and
+ * call its 'complete' method, passing in all the received query
+ * arguments.
+ *
+ * There are multiple possible return types possible from that
+ * method. These indicate the whether or not the login was successful,
+ * and include any additional information appropriate for their type.

+/**
+ * This module implements a VERY limited parser that finds <link> tags
+ * in the head of HTML or XHTML documents and parses out their
+ * attributes according to the OpenID spec. It is a liberal parser,
+ * but it requires these things from the data in order to work:
+ *
+ * - There must be an open <html> tag
+ *
+ * - There must be an open <head> tag inside of the <html> tag
+ *
+ * - Only <link>s that are found inside of the <head> tag are parsed
+ * (this is by design)
+ *
+ * - The parser follows the OpenID specification in resolving the
+ * attributes of the link tags. This means that the attributes DO
+ * NOT get resolved as they would by an XML or HTML parser. In
+ * particular, only certain entities get replaced, and href
+ * attributes do not get resolved relative to a base URL.
+ *
+ * From http://openid.net/specs.bml:
+ *
+ * - The openid.server URL MUST be an absolute URL. OpenID consumers
+ * MUST NOT attempt to resolve relative URLs.
+ *
+ * - The openid.server URL MUST NOT include entities other than &,
+ * <, >, and ".
+ *
+ * The parser ignores SGML comments and <![CDATA[blocks]]>. Both kinds
+ * of quoting are allowed for attributes.
+ *
+ * The parser deals with invalid markup in these ways:
+ *
+ * - Tag names are not case-sensitive
+ *
+ * - The <html> tag is accepted even when it is not at the top level
+ *
+ * - The <head> tag is accepted even when it is not a direct child of
+ * the <html> tag, but a <html> tag must be an ancestor of the
+ * <head> tag
+ *
+ * - <link> tags are accepted even when they are not direct children
+ * of the <head> tag, but a <head> tag must be an ancestor of the
+ * <link> tag
+ *
+ * - If there is no closing tag for an open <html> or <head> tag, the
+ * remainder of the document is viewed as being inside of the
+ * tag. If there is no closing tag for a <link> tag, the link tag is
+ * treated as a short tag. Exceptions to this rule are that <html>
+ * closes <html> and <body> or <head> closes <head>
+ *
+ * - Attributes of the <link> tag are not required to be quoted.
+ *
+ * - In the case of duplicated attribute names, the attribute coming
+ * last in the tag will be the value returned.
+ *
+ * - Any text that does not parse as an attribute within a link tag
+ * will be ignored. (e.g. <link pumpkin rel='openid.server' /> will
+ * ignore pumpkin)
+ *
+ * - If there are more than one <html> or <head> tag, the parser only
+ * looks inside of the first one.
+ *
+ * - The contents of <script> tags are ignored entirely, except
+ * unclosed <script> tags. Unclosed <script> tags are ignored.
+ *
+ * - Any other invalid markup is ignored, including unclosed SGML
+ * comments and unclosed <![CDATA[blocks.

+ * Auth_OpenID_SRegRequest::fromOpenIDRequest}, gets the user's
+ * approval and data, creates an {@link Auth_OpenID_SRegResponse}
+ * object and adds it to the id_res response:
+ *
+ * $sreg_req = Auth_OpenID_SRegRequest::fromOpenIDRequest(

+ * $sreg_resp = Auth_OpenID_SRegResponse::extractResponse(
+ * $sreg_req, $user_data);
+ * $sreg_resp->toMessage($openid_response->fields);
+ *
+ * 3. The relying party uses {@link
+ * Auth_OpenID_SRegResponse::fromSuccessResponse} to extract the data
+ * from the OpenID response:

+/**
+ * OpenID server protocol and logic.
+ *
+ * Overview
+ *
+ * An OpenID server must perform three tasks:
+ *
+ * 1. Examine the incoming request to determine its nature and validity.
+ * 2. Make a decision about how to respond to this request.
+ * 3. Format the response according to the protocol.
+ *
+ * The first and last of these tasks may performed by the {@link
+ * Auth_OpenID_Server::decodeRequest()} and {@link
+ * Auth_OpenID_Server::encodeResponse} methods. Who gets to do the
+ * intermediate task -- deciding how to respond to the request -- will
+ * depend on what type of request it is.
+ *
+ * If it's a request to authenticate a user (a 'checkid_setup' or
+ * 'checkid_immediate' request), you need to decide if you will assert
+ * that this user may claim the identity in question. Exactly how you
+ * do that is a matter of application policy, but it generally
+ * involves making sure the user has an account with your system and
+ * is logged in, checking to see if that identity is hers to claim,
+ * and verifying with the user that she does consent to releasing that
+ * information to the party making the request.
+ *
+ * Examine the properties of the {@link Auth_OpenID_CheckIDRequest}
+ * object, and if and when you've come to a decision, form a response
+ * by calling {@link Auth_OpenID_CheckIDRequest::answer()}.
+ *
+ * Other types of requests relate to establishing associations between
+ * client and server and verifing the authenticity of previous
+ * communications. {@link Auth_OpenID_Server} contains all the logic
+ * and data necessary to respond to such requests; just pass it to
+ * {@link Auth_OpenID_Server::handleRequest()}.
+ *
+ * OpenID Extensions
+ *
+ * Do you want to provide other information for your users in addition
+ * to authentication? Version 1.2 of the OpenID protocol allows
+ * consumers to add extensions to their requests. For example, with
+ * sites using the Simple Registration
+ * Extension
+ * (http://www.openidenabled.com/openid/simple-registration-extension/),
+ * a user can agree to have their nickname and e-mail address sent to
+ * a site when they sign up.
+ *
+ * Since extensions do not change the way OpenID authentication works,
+ * code to handle extension requests may be completely separate from
+ * the {@link Auth_OpenID_Request} class here. But you'll likely want
+ * data sent back by your extension to be signed. {@link
+ * Auth_OpenID_ServerResponse} provides methods with which you can add
+ * data to it which can be signed with the other data in the OpenID
+ * signature.
+ *
+ * For example:
+ *
+ * <pre> // when request is a checkid_* request
+ * $response = $request->answer(true);
+ * // this will a signed 'openid.sreg.timezone' parameter to the response
+ * response.addField('sreg', 'timezone', 'America/Los_Angeles')</pre>
+ *
+ * Stores
+ *
+ * The OpenID server needs to maintain state between requests in order
+ * to function. Its mechanism for doing this is called a store. The
+ * store interface is defined in Interface.php. Additionally, several
+ * concrete store implementations are provided, so that most sites
+ * won't need to implement a custom store. For a store backed by flat
+ * files on disk, see {@link Auth_OpenID_FileStore}. For stores based
+ * on MySQL, SQLite, or PostgreSQL, see the {@link
+ * Auth_OpenID_SQLStore} subclasses.
+ *
+ * Upgrading
+ *
+ * The keys by which a server looks up associations in its store have
+ * changed in version 1.2 of this library. If your store has entries
+ * created from version 1.0 code, you should empty it.
+ *
+ * PHP versions 4 and 5

+/**
+ * This is the core of the PHP Yadis library. This is the only class
+ * a user needs to use to perform Yadis discovery. This class
+ * performs the discovery AND stores the result of the discovery.
+ *
+ * First, require this library into your program source:
+ *
+ * <pre> require_once "Auth/Yadis/Yadis.php";</pre>
+ *
+ * To perform Yadis discovery, first call the "discover" method
+ * statically with a URI parameter:
+ *
+ * <pre> $http_response = array();
+ * $fetcher = Auth_Yadis_Yadis::getHTTPFetcher();
+ * $yadis_object = Auth_Yadis_Yadis::discover($uri,
+ * $http_response, $fetcher);</pre>
+ *
+ * If the discovery succeeds, $yadis_object will be an instance of
+ * {@link Auth_Yadis_Yadis}. If not, it will be null. The XRDS
+ * document found during discovery should have service descriptions,
+ * which can be accessed by calling
+ *
+ * <pre> $service_list = $yadis_object->services();</pre>
+ *
+ * which returns an array of objects which describe each service.
+ * These objects are instances of Auth_Yadis_Service. Each object
+ * describes exactly one whole Service element, complete with all of
+ * its Types and URIs (no expansion is performed). The common use
+ * case for using the service objects returned by services() is to
+ * write one or more filter functions and pass those to services():
+ *
+ * <pre> $service_list = $yadis_object->services(
+ * array("filterByURI",
+ * "filterByExtension"));</pre>
+ *
+ * The filter functions (whose names appear in the array passed to
+ * services()) take the following form:
+ *
+ * <pre> function myFilter(&$service) {
+ * // Query $service object here. Return true if the service
+ * // matches your query; false if not.
+ * }</pre>
+ *
+ * This is an example of a filter which uses a regular expression to
+ * match the content of URI tags (note that the Auth_Yadis_Service
+ * class provides a getURIs() method which you should use instead of
+ * this contrived example):
+ *
+ * <pre>
+ * function URIMatcher(&$service) {
+ * foreach ($service->getElements('xrd:URI') as $uri) {
+ * if (preg_match("/some_pattern/",
+ * $service->parser->content($uri))) {
+ * return true;
+ * }
+ * }
+ * return false;
+ * }</pre>
+ *
+ * The filter functions you pass will be called for each service
+ * object to determine which ones match the criteria your filters
+ * specify. The default behavior is that if a given service object
+ * matches ANY of the filters specified in the services() call, it
+ * will be returned. You can specify that a given service object will
+ * be returned ONLY if it matches ALL specified filters by changing
+ * the match mode of services():
+ *
+ * <pre> $yadis_object->services(array("filter1", "filter2"),
+ * SERVICES_YADIS_MATCH_ALL);</pre>
+ *
+ * See {@link SERVICES_YADIS_MATCH_ALL} and {@link
+ * SERVICES_YADIS_MATCH_ANY}.
+ *
+ * Services described in an XRDS should have a library which you'll
+ * probably be using. Those libraries are responsible for defining
+ * filters that can be used with the "services()" call. If you need
+ * to write your own filter, see the documentation for {@link
+ * Auth_Yadis_Service}.

+ *
+ *
+ * <samp>DB_PORTABILITY_DELETE_COUNT</samp>
+ * force reporting the number of rows deleted
+ *
+ * Some DBMS's don't count the number of rows deleted when performing

+ *
+ * <samp>DB_PORTABILITY_NULL_TO_EMPTY</samp>

+ * RFC 822 Email address list validation Utility
+ *
+ * What is it?
+ *
+ * This class will take an address string, and parse it into it's consituent
+ * parts, be that either addresses, groups, or combinations. Nested groups
+ * are not supported. The structure it returns is pretty straight forward,
+ * and is similar to that provided by the imap_rfc822_parse_adrlist(). Use
+ * print_r() to view the structure.
+ *
+ * How do I use it?
+ *
+ * $address_string = 'My Group: "Richard" <richard@localhost> (A comment), ted@example.com (Ted Bloggs), Barney;';
+ * $structure = Mail_RFC822::parseAddressList($address_string, 'example.com', true)
+ * print_r($structure);

+ *
+ * If you want a destructor in your class, inherit PEAR and make a
+ * destructor method called _yourclassname (same name as the
+ * constructor, but with a "_" prefix). Also, in your constructor you
+ * have to call the PEAR constructor: $this->PEAR();.
+ * The destructor method will be called without parameters. Note that
+ * at in some SAPI implementations (such as Apache), any output during
+ * the request shutdown (in which destructors are called) seems to be
+ * discarded. If you need to get any debug information from your
+ * destructor, use error_log(), syslog() or something similar.
+ *
+ * IMPORTANT! To use the emulated destructors you need to create the
+ * objects by reference: $obj =& new PEAR_child;

+
+PHP Markdown
+============
+
+Description
+-----------
+
+This is a PHP translation of the original Markdown formatter written in
+Perl by John Gruber.
+
+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 <div> and <table> as well).
+
+For more information about Markdown's syntax, see:
+
+<http://daringfireball.net/projects/markdown/>
+
+
