+/**
+ * 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;
+ *  }

+     *                that should be used for all output
+     *  'message'     the parameter is a string with an informational message
+     *  'saveas'      may be used to save with a different file name, the
+     *                parameter is the filename that is about to be used.
+     *                If a 'saveas' callback returns a non-empty string,
+     *                that file name will be used as the filename instead.

+     *                the basename of the file.
+     *  'start'       download is starting, parameter is number of bytes
+     *                that are expected, or -1 if unknown
+     *  'bytesread'   parameter is the number of bytes read so far
+     *  'done'        download is complete, parameter is the total number
+     *                of bytes read
+     *  'connfailed'  if the TCP/SSL connection fails, this callback is called
+     *                with array(host,port,errno,errmsg)
+     *  'writefailed' if writing to disk fails, this callback is called
+     *                with array(destfile,errmsg)
+     *
+     * If an HTTP proxy has been configured (http_proxy PEAR_Config

+ * Simple tasks operate on 1 file.  Multiple tasks are executed after all files have been

+ * The Post-install script task simply takes advantage of the fact that it will be run

+ * PEAR command class, a simple factory class for administrative
+ * commands.
+ *
+ * How to implement command classes:
+ *
+ * - The class must be called PEAR_Command_Nnn, installed in the
+ *   "PEAR/Common" subdir, with a method called getCommands() that
+ *   returns an array of the commands implemented by the class (see
+ *   PEAR/Command/Install.php for an example).
+ *
+ * - The class must implement a run() function that is called with three
+ *   params:
+ *
+ *    (string) command name
+ *    (array)  assoc array with options, freely defined by each
+ *             command, for example:
+ *             array('force' => true)
+ *    (array)  list of the other parameters
+ *
+ *   The run() function returns a PEAR_CommandResponse object.  Use
+ *   these methods to get information:
+ *
+ *    int getStatus()   Returns PEAR_COMMAND_(SUCCESS|FAILURE|PARTIAL)
+ *                      *_PARTIAL means that you need to issue at least
+ *                      one more command to complete the operation
+ *                      (used for example for validation steps).
+ *
+ *    string getMessage()  Returns a message for the user.  Remember,
+ *                         no HTML or other interface-specific markup.
+ *
+ *   If something unexpected happens, run() returns a PEAR error.
+ *
+ * - DON'T OUTPUT ANYTHING! Return text for output instead.
+ *
+ * - DON'T USE HTML! The text you return will be used from both Gtk,
+ *   web and command-line interfaces, so for now, keep everything to
+ *   plain text.
+ *
+ * - DON'T USE EXIT OR DIE! Always use pear errors.  From static
+ *   classes do PEAR::raiseError(), from other classes do
+ *   $this->raiseError().

+/**
+ * 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

+Installs one or more PEAR packages.  You can specify a package to
+install in four ways:
+"Package-1.0.tgz" : installs from a local file
+"http://example.com/Package-1.0.tgz" : installs from
+anywhere on the net.
+"package.xml" : installs the package described in
+package.xml.  Useful for testing, or for wrapping a PEAR package in
+another package manager such as RPM.
+"Package[-version/state][.tar]" : queries your default channel\'s server
+({config master_server}) and downloads the newest package with
+the preferred quality/state ({config preferred_state}).
+To retrieve Package version 1.1, use "Package-1.1," to retrieve
+Package state beta, use "Package-beta."  To retrieve an uncompressed
+file, append .tar (make sure there is no file by the same name first)
+To download a package from another channel, prefix with the channel name like
+"channel/Package"
+More than one package may be specified at once.  It is ok to mix these
+four ways of specifying packages.

+&quot;http://example.com/Package-1.0.tgz&quot; : installs from
+anywhere on the net.
+&quot;package.xml&quot; : installs the package described in
+package.xml.  Useful for testing, or for wrapping a PEAR package in
+another package manager such as RPM.
+&quot;Package[-version/state][.tar]&quot; : queries your default channel&apos;s server
+({config master_server}) and downloads the newest package with
+the preferred quality/state ({config preferred_state}).
+To retrieve Package version 1.1, use &quot;Package-1.1,&quot; to retrieve
+Package state beta, use &quot;Package-beta.&quot;  To retrieve an uncompressed
+file, append .tar (make sure there is no file by the same name first)
+To download a package from another channel, prefix with the channel name like
+&quot;channel/Package&quot;
+More than one package may be specified at once.  It is ok to mix these
+four ways of specifying packages.

+Creates a PECL package from its description file (usually called
+package.xml).  If a second packagefile is passed in, then
+the packager will check to make sure that one is a package.xml
+version 1.0, and the other is a package.xml version 2.0.  The
+package.xml version 1.0 will be saved as &quot;package.xml&quot; in the archive,
+and the other as &quot;package2.xml&quot; in the archive&quot;
+If no second file is passed in, and [descfile] is a package.xml 2.0,
+an automatic conversion will be made to a package.xml 1.0.  Note that
+only simple package.xml 2.0 will be converted.  package.xml 2.0 with:
+ - dependency types other than required/optional PECL package/ext/php/pearinstaller
+ - more than one extsrcrelease/zendextsrcrelease
+ - zendextbinrelease, extbinrelease, phprelease, or bundle release type
+ - dependency groups
+ - ignore tags in release filelist
+ - tasks other than replace
+ - custom roles
+will cause pickle to fail, and output an error message.  If your package2.xml
+uses any of these features, you are best off using PEAR_PackageFileManager to
+generate both package.xml.</doc>
