+Mail
+****
+Class that provides multiple interfaces for sending emails.
+
+PEAR's Mail package defines an interface for implementing mailers under the
+PEAR hierarchy.
+It also provides supporting functions useful to multiple mailer backends.
+
+Currently supported backends include:
+
+- PHP's native ``mail()`` function
+- sendmail
+- SMTP
+
+This package also provides a `RFC 822`__ email address list validation utility class.
+
+Use Mail in combination with `Mail_Mime`__ to send HTML emails or emails with
+attachments - have a look at the example__.

+======================
+ The Net_SMTP Package
+======================
+
+--------------------
+ User Documentation
+--------------------
+
+:Author:    Jon Parise
+:Contact:   jon@php.net
+
+.. contents:: Table of Contents
+.. section-numbering::
+
+Dependencies
+============
+
+The ``PEAR_Error`` Class
+------------------------
+
+The Net_SMTP package uses the `PEAR_Error`_ class for all of its `error
+handling`_.
+
+The ``Net_Socket`` Package
+--------------------------
+
+The Net_Socket_ package is used as the basis for all network communications.
+Connection options can be specified via the `$socket_options` construction
+parameter::
+
+    $socket_options = array('ssl' => array('verify_peer_name' => false));
+    $smtp = new Net_SMTP($host, null, null, false, 0, $socket_options);
+
+**Note:** PHP 5.6 introduced `OpenSSL changes`_. Peer certificate verification
+is now enabled by default. Although not recommended, `$socket_options` can be
+used to disable peer verification (as shown above).
+
+.. _OpenSSL changes: http://php.net/manual/en/migration56.openssl.php
+
+The ``Auth_SASL`` Package
+-------------------------
+
+The `Auth_SASL`_ package is an optional dependency.  If it is available, the
+Net_SMTP package will be able to support the DIGEST-MD5_ and CRAM-MD5_ SMTP
+authentication methods.  Otherwise, only the LOGIN_ and PLAIN_ methods will
+be available.
+
+Error Handling
+==============
+
+All of the Net_SMTP class's public methods return a PEAR_Error_ object if an
+error occurs.  The standard way to check for a PEAR_Error object is by using
+`PEAR::isError()`_::
+
+    if (PEAR::isError($error = $smtp->connect())) {
+        die($error->getMessage());
+    }
+
+.. _PEAR::isError(): http://pear.php.net/manual/en/core.pear.pear.iserror.php
+
+SMTP Authentication
+===================
+
+The Net_SMTP package supports the SMTP authentication standard (as defined
+by RFC-2554_).  The Net_SMTP package supports the following authentication
+methods, in order of preference:
+
+.. _RFC-2554: http://www.ietf.org/rfc/rfc2554.txt
+
+DIGEST-MD5
+----------
+
+The DIGEST-MD5 authentication method uses `RSA Data Security Inc.`_'s MD5
+Message Digest algorithm.  It is considered the most secure method of SMTP
+authentication.
+
+**Note:** The DIGEST-MD5 authentication method is only supported if the
+AUTH_SASL_ package is available.
+
+.. _RSA Data Security Inc.: http://www.rsasecurity.com/
+
+CRAM-MD5
+--------
+
+The CRAM-MD5 authentication method has been superseded by the DIGEST-MD5_
+method in terms of security.  It is provided here for compatibility with
+older SMTP servers that may not support the newer DIGEST-MD5 algorithm.
+
+**Note:** The CRAM-MD5 authentication method is only supported if the
+AUTH_SASL_ package is available.
+
+LOGIN
+-----
+
+The LOGIN authentication method encrypts the user's password using the
+Base64_ encoding scheme.  Because decrypting a Base64-encoded string is
+trivial, LOGIN is not considered a secure authentication method and should
+be avoided.
+
+.. _Base64: http://www.php.net/manual/en/function.base64-encode.php
+
+PLAIN
+-----
+
+The PLAIN authentication method sends the user's password in plain text.
+This method of authentication is not secure and should be avoided.
+
+Secure Connections
+==================
+
+If `secure socket transports`_ have been enabled in PHP, it is possible to
+establish a secure connection to the remote SMTP server::
+
+    $smtp = new Net_SMTP('ssl://mail.example.com', 465);
+
+This example connects to ``mail.example.com`` on port 465 (a common SMTPS
+port) using the ``ssl://`` transport.
+
+.. _secure socket transports: http://www.php.net/transports
+
+Sending Data
+============
+
+Message data is sent using the ``data()`` method.  The data can be supplied
+as a single string or as an open file resource.
+
+If a string is provided, it is passed through the `data quoting`_ system and
+sent to the socket connection as a single block.  These operations are all
+memory-based, so sending large messages may result in high memory usage.
+
+If an open file resource is provided, the ``data()`` method will read the
+message data from the file line-by-line.  Each chunk will be quoted and sent
+to the socket connection individually, reducing the overall memory overhead of
+this data sending operation.
+
+Header data can be specified separately from message body data by passing it
+as the optional second parameter to ``data()``.  This is especially useful
+when an open file resource is being used to supply message data because it
+allows header fields (like *Subject:*) to be built dynamically at runtime.
+
+::
+
+    $smtp->data($fp, "Subject: My Subject");
+
+Data Quoting
+============
+
+By default, all outbound string data is quoted in accordance with SMTP
+standards.  This means that all native Unix (``\n``) and Mac (``\r``) line
+endings are converted to Internet-standard CRLF (``\r\n``) line endings.
+Also, because the SMTP protocol uses a single leading period (``.``) to signal
+an end to the message data, single leading periods in the original data
+string are "doubled" (e.g. "``..``").
+
+These string transformation can be expensive when large blocks of data are
+involved.  For example, the Net_SMTP package is not aware of MIME parts (it
+just sees the MIME message as one big string of characters), so it is not
+able to skip non-text attachments when searching for characters that may
+need to be quoted.
+
+Because of this, it is possible to extend the Net_SMTP class in order to
+implement your own custom quoting routine.  Just create a new class based on
+the Net_SMTP class and reimplement the ``quotedata()`` method::
+
+    require 'Net_SMTP.php';
+
+    class Net_SMTP_custom extends Net_SMTP
+    {
+        function quotedata($data)
+        {
+            /* Perform custom data quoting */
+        }
+    }
+
+Note that the ``$data`` parameter will be passed to the ``quotedata()``
+function `by reference`_.  This means that you can operate directly on
+``$data``.  It also the overhead of copying a large ``$data`` string to and
+from the ``quotedata()`` method.
+
+.. _by reference: http://www.php.net/manual/en/language.references.pass.php
+
+Server Responses
+================
+
+The Net_SMTP package retains the server's last response for further
+inspection.  The ``getResponse()`` method returns a 2-tuple (two element
+array) containing the server's response code as an integer and the response's
+arguments as a string.
+
+Upon a successful connection, the server's greeting string is available via
+the ``getGreeting()`` method.
+
+Debugging
+=========
+
+The Net_SMTP package contains built-in debugging output routines (disabled by
+default).  Debugging output must be explicitly enabled via the ``setDebug()``
+method::
+
+    $smtp->setDebug(true);
+
+The debugging messages will be sent to the standard output stream by default.
+If you need more control over the output, you can optionally install your own
+debug handler.
+
+::
+
+    function debugHandler($smtp, $message)
+    {
+        echo "[$smtp->host] $message\n";
+    }
+
+    $smtp->setDebug(true, "debugHandler");
+
+
+Examples
+========
+
+Basic Use
+---------
+
+The following script demonstrates how a simple email message can be sent
+using the Net_SMTP package::
+
+    require 'Net/SMTP.php';
+
+    $host = 'mail.example.com';
+    $from = 'user@example.com';
+    $rcpt = array('recipient1@example.com', 'recipient2@example.com');
+    $subj = "Subject: Test Message\n";
+    $body = "Body Line 1\nBody Line 2";
+
+    /* Create a new Net_SMTP object. */
+    if (! ($smtp = new Net_SMTP($host))) {
+        die("Unable to instantiate Net_SMTP object\n");
+    }
+
+    /* Connect to the SMTP server. */
+    if (PEAR::isError($e = $smtp->connect())) {
+        die($e->getMessage() . "\n");
+    }
+
+    /* Send the 'MAIL FROM:' SMTP command. */
+    if (PEAR::isError($smtp->mailFrom($from))) {
+        die("Unable to set sender to <$from>\n");
+    }
+
+    /* Address the message to each of the recipients. */
+    foreach ($rcpt as $to) {
+        if (PEAR::isError($res = $smtp->rcptTo($to))) {
+            die("Unable to add recipient <$to>: " . $res->getMessage() . "\n");
+        }
+    }
+
+    /* Set the body of the message. */
+    if (PEAR::isError($smtp->data($subj . "\r\n" . $body))) {
+        die("Unable to send data\n");
+    }
+
+    /* Disconnect from the SMTP server. */
+    $smtp->disconnect();

+******************************
+Minimal set of PEAR core files
+******************************
+
+This repository provides a set of files from ``pear-core``
+that are often used in PEAR packages.
+
+It follows the `pear-core`__ repository and gets updated whenever a new
+PEAR version is released.
+
+It's meant to be used as dependency for composer packages.
+
+__ https://github.com/pear/pear-core
+
+==============
+Included files
+==============
+- ``OS/Guess.php``
+- ``PEAR.php``
+- ``PEAR/Error.php``
+- ``PEAR/ErrorStack.php``
+- ``System.php``
+
+
+``PEAR/Error.php`` is a dummy file that only includes ``PEAR.php``,
+to make autoloaders work without problems.

+/**
+ * Error Stack Implementation
+ * 
+ * This is an incredibly simple implementation of a very complex error handling
+ * facility.  It contains the ability
+ * to track multiple errors from multiple packages simultaneously.  In addition,
+ * it can track errors of many levels, save data along with the error, context
+ * information such as the exact file, line number, class and function that
+ * generated the error, and if necessary, it can raise a traditional PEAR_Error.
+ * It has built-in support for PEAR::Log, to log errors as they occur
+ * 
+ * Since version 0.2alpha, it is also possible to selectively ignore errors,
+ * through the use of an error callback, see {@link pushCallback()}
+ * 
+ * Since version 0.3alpha, it is possible to specify the exception class
+ * returned from {@link push()}
+ *
+ * Since version PEAR1.3.2, ErrorStack no longer instantiates an exception class.  This can
+ * still be done quite handily in an error callback or by manipulating the returned array

+* System offers cross platform compatible system functions

+* Static functions for different operations. Should work under
+* Unix and Windows. The names and usage has been taken from its respectively
+* GNU commands. The functions will return (bool) false on error and will
+* trigger the error with the PHP trigger_error() function (you can silence
+* the error by prefixing a '@' sign after the function call, but this
+* is not recommended practice.  Instead use an error handler with
+* {@link set_error_handler()}).
+*
+* Documentation on this class you can find in:
+* http://pear.php.net/manual/
+*
+* Example usage:
+* if (!@System::rm('-r file1 dir1')) {
+*    print "could not delete file1 or dir1";
+* }
+*
+* In case you need to to pass file names with spaces,
+* pass the params as an array:
+*
+* System::rm(array('-r', $file1, $dir1));

+/**
+ * Base PEAR_Exception Class
+ *
+ * 1) Features:
+ *
+ * - Nestable exceptions (throw new PEAR_Exception($msg, $prev_exception))
+ * - Definable triggers, shot when exceptions occur
+ * - Pretty and informative error messages
+ * - Added more context info available (like class, method or cause)
+ * - cause can be a PEAR_Exception or an array of mixed
+ *   PEAR_Exceptions/PEAR_ErrorStack warnings
+ * - callbacks for specific exception classes and their children
+ *
+ * 2) Ideas:
+ *
+ * - Maybe a way to define a 'template' for the output
+ *
+ * 3) Inherited properties from PHP Exception Class:
+ *
+ * protected $message
+ * protected $code
+ * protected $line
+ * protected $file
+ * private   $trace
+ *
+ * 4) Inherited methods from PHP Exception Class:
+ *
+ * __clone
+ * __construct
+ * getMessage
+ * getCode
+ * getFile
+ * getLine
+ * getTraceSafe
+ * getTraceSafeAsString
+ * __toString
+ *
+ * 5) Usage example
+ *
+ * <code>
+ *  require_once 'PEAR/Exception.php';
+ *
+ *  class Test {
+ *     function foo() {
+ *         throw new PEAR_Exception('Error Message', ERROR_CODE);
+ *     }
+ *  }
+ *
+ *  function myLogger($pear_exception) {
+ *     echo $pear_exception->getMessage();
+ *  }
+ *  // each time a exception is thrown the 'myLogger' will be called
+ *  // (its use is completely optional)
+ *  PEAR_Exception::addObserver('myLogger');
+ *  $test = new Test;
+ *  try {
+ *     $test->foo();
+ *  } catch (PEAR_Exception $e) {
+ *     print $e;
+ *  }
