-Overview :
-----------
-
-  The Archive_Tar class helps in creating and managing GNU TAR format
-  files compressed by GNU ZIP or not. 
-  The class offers basic functions like creating an archive, adding
-  files in the archive, extracting files from the archive and listing
-  the archive content. 
-  It also provide advanced functions that allow the adding and
-  extraction of files with path manipulation. 
-
-
-Sample :
---------
-
-  // ----- Creating the object (uncompressed archive)
-  $tar_object = new Archive_Tar("tarname.tar");
-  $tar_object->setErrorHandling(PEAR_ERROR_PRINT);
-
-  // ----- Creating the archive
-  $v_list[0]="file.txt";
-  $v_list[1]="data/";
-  $v_list[2]="file.log";
-  $tar_object->create($v_list);
-
-  // ----- Adding files
-  $v_list[0]="dev/file.txt";
-  $v_list[1]="dev/data/";
-  $v_list[2]="log/file.log";
-  $tar_object->add($v_list);
-
-  // ----- Adding more files
-  $tar_object->add("release/newfile.log release/readme.txt");
-
-  // ----- Listing the content
-  if (($v_list  =  $tar_object->listContent()) != 0)
-    for ($i=0; $i<sizeof($v_list); $i++)
-    {
-      echo "Filename :'".$v_list[$i][filename]."'<br>";
-      echo " .size :'".$v_list[$i][size]."'<br>";
-      echo " .mtime :'".$v_list[$i][mtime]."' (".date("l dS of F Y h:i:s A", $v_list[$i][mtime]).")<br>";
-      echo " .mode :'".$v_list[$i][mode]."'<br>";
-      echo " .uid :'".$v_list[$i][uid]."'<br>";
-      echo " .gid :'".$v_list[$i][gid]."'<br>";
-      echo " .typeflag :'".$v_list[$i][typeflag]."'<br>";
-    }
-
-  // ----- Extracting the archive in directory "install"
-  $tar_object->extract("install");

-
-Method : Archive_Tar($p_tarname, $compress = null)
-Description :
-  Archive_Tar Class constructor. This flavour of the constructor only
-  declare a new Archive_Tar object, identifying it by the name of the
-  tar file.
-  If the compress argument is set the tar will be read or created as a
-  gzip or bz2 compressed TAR file. 
-Arguments :
-  $p_tarname : A valid filename for the tar archive file.
-  $p_compress : can be null, 'gz' or 'bz2'. For
-                compatibility reason it can also be true. This
-                parameter indicates if gzip or bz2 compression
-                is required. 
-Return value :
-  The Archive_Tar object.
-Sample :
-  $tar_object = new Archive_Tar("tarname.tar");
-  $tar_object_compressed = new Archive_Tar("tarname.tgz", true);
-How it works :
-  Initialize the object.
-
-Method : create($p_filelist)
-Description :
-  This method creates the archive file and add the files / directories
-  that are listed in $p_filelist. 
-  If the file already exists and is writable, it is replaced by the
-  new tar. It is a create and not an add. If the file exists and is
-  read-only or is a directory it is not replaced. The method return
-  false and a PEAR error text. 
-  The $p_filelist parameter can be an array of string, each string
-  representing a filename or a directory name with their path if
-  needed. It can also be a single string with names separated by a
-  single blank. 
-  See also createModify() method for more details.
-Arguments :
-  $p_filelist : An array of filenames and directory names, or a single
-  string with names separated by a single blank space. 
-Return value :
-  true on success, false on error.
-Sample 1 :
-  $tar_object = new Archive_Tar("tarname.tar");
-  $tar_object->setErrorHandling(PEAR_ERROR_PRINT);  // Optional error handling
-  $v_list[0]="file.txt";
-  $v_list[1]="data/"; (Optional '/' at the end)
-  $v_list[2]="file.log";
-  $tar_object->create($v_list);
-Sample 2 :
-  $tar_object = new Archive_Tar("tarname.tar");
-  $tar_object->setErrorHandling(PEAR_ERROR_PRINT);  // Optional error handling
-  $tar_object->create("file.txt data/ file.log");
-How it works :
-  Just calling the createModify() method with the right parameters.
-
-Method : createModify($p_filelist, $p_add_dir, $p_remove_dir = "")
-Description :
-  This method creates the archive file and add the files / directories
-  that are listed in $p_filelist. 
-  If the file already exists and is writable, it is replaced by the
-  new tar. It is a create and not an add. If the file exists and is
-  read-only or is a directory it is not replaced. The method return
-  false and a PEAR error text. 
-  The $p_filelist parameter can be an array of string, each string
-  representing a filename or a directory name with their path if
-  needed. It can also be a single string with names separated by a
-  single blank. 
-  The path indicated in $p_remove_dir will be removed from the
-  memorized path of each file / directory listed when this path
-  exists. By default nothing is removed (empty path "") 
-  The path indicated in $p_add_dir will be added at the beginning of
-  the memorized path of each file / directory listed. However it can
-  be set to empty "". The adding of a path is done after the removing
-  of path. 
-  The path add/remove ability enables the user to prepare an archive
-  for extraction in a different path than the origin files are. 
-  See also addModify() method for file adding properties.
-Arguments :
-  $p_filelist : An array of filenames and directory names, or a single
-                string with names separated by a single blank space.
-  $p_add_dir : A string which contains a path to be added to the
-               memorized path of each element in the list. 
-  $p_remove_dir : A string which contains a path to be removed from
-                  the memorized path of each element in the list, when
-		  relevant.
-Return value :
-  true on success, false on error.
-Sample 1 :
-  $tar_object = new Archive_Tar("tarname.tar");
-  $tar_object->setErrorHandling(PEAR_ERROR_PRINT);  // Optional error handling
-  $v_list[0]="file.txt";
-  $v_list[1]="data/"; (Optional '/' at the end)
-  $v_list[2]="file.log";
-  $tar_object->createModify($v_list, "install");
-  // files are stored in the archive as :
-  //   install/file.txt
-  //   install/data
-  //   install/data/file1.txt
-  //   install/data/... all the files and sub-dirs of data/
-  //   install/file.log
-Sample 2 :
-  $tar_object = new Archive_Tar("tarname.tar");
-  $tar_object->setErrorHandling(PEAR_ERROR_PRINT);  // Optional error handling
-  $v_list[0]="dev/file.txt";
-  $v_list[1]="dev/data/"; (Optional '/' at the end)
-  $v_list[2]="log/file.log";
-  $tar_object->createModify($v_list, "install", "dev");
-  // files are stored in the archive as :
-  //   install/file.txt
-  //   install/data
-  //   install/data/file1.txt
-  //   install/data/... all the files and sub-dirs of data/
-  //   install/log/file.log
-How it works :
-  Open the file in write mode (erasing the existing one if one),
-  call the _addList() method for adding the files in an empty archive,
-  add the tar footer (512 bytes block), close the tar file.
-
-
-Method : addModify($p_filelist, $p_add_dir, $p_remove_dir="")
-Description :
-  This method add the files / directories listed in $p_filelist at the
-  end of the existing archive. If the archive does not yet exists it
-  is created.
-  The $p_filelist parameter can be an array of string, each string
-  representing a filename or a directory name with their path if
-  needed. It can also be a single string with names separated by a
-  single blank. 
-  The path indicated in $p_remove_dir will be removed from the
-  memorized path of each file / directory listed when this path
-  exists. By default nothing is removed (empty path "") 
-  The path indicated in $p_add_dir will be added at the beginning of
-  the memorized path of each file / directory listed. However it can
-  be set to empty "". The adding of a path is done after the removing
-  of path. 
-  The path add/remove ability enables the user to prepare an archive
-  for extraction in a different path than the origin files are. 
-  If a file/dir is already in the archive it will only be added at the
-  end of the archive. There is no update of the existing archived
-  file/dir. However while extracting the archive, the last file will
-  replace the first one. This results in a none optimization of the
-  archive size. 
-  If a file/dir does not exist the file/dir is ignored. However an
-  error text is send to PEAR error. 
-  If a file/dir is not readable the file/dir is ignored. However an
-  error text is send to PEAR error. 
-  If the resulting filename/dirname (after the add/remove option or
-  not) string is greater than 99 char, the file/dir is
-  ignored. However an error text is send to PEAR error. 
-Arguments :
-  $p_filelist : An array of filenames and directory names, or a single
-                string with names separated by a single blank space. 
-  $p_add_dir : A string which contains a path to be added to the
-               memorized path of each element in the list. 
-  $p_remove_dir : A string which contains a path to be removed from
-                  the memorized path of each element in the list, when
-		  relevant.
-Return value :
-  true on success, false on error.
-Sample 1 :
-  $tar_object = new Archive_Tar("tarname.tar");
-  [...]
-  $v_list[0]="dev/file.txt";
-  $v_list[1]="dev/data/"; (Optional '/' at the end)
-  $v_list[2]="log/file.log";
-  $tar_object->addModify($v_list, "install");
-  // files are stored in the archive as :
-  //   install/file.txt
-  //   install/data
-  //   install/data/file1.txt
-  //   install/data/... all the files and sub-dirs of data/
-  //   install/file.log
-Sample 2 :
-  $tar_object = new Archive_Tar("tarname.tar");
-  [...]
-  $v_list[0]="dev/file.txt";
-  $v_list[1]="dev/data/"; (Optional '/' at the end)
-  $v_list[2]="log/file.log";
-  $tar_object->addModify($v_list, "install", "dev");
-  // files are stored in the archive as :
-  //   install/file.txt
-  //   install/data
-  //   install/data/file1.txt
-  //   install/data/... all the files and sub-dirs of data/
-  //   install/log/file.log
-How it works :
-  If the archive does not exists it create it and add the files.
-  If the archive does exists and is not compressed, it open it, jump
-  before the last empty 512 bytes block (tar footer) and add the files
-  at this point.
-  If the archive does exists and is compressed, a temporary copy file
-  is created. This temporary file is then 'gzip' read block by block
-  until the last empty block. The new files are then added in the
-  compressed file.
-  The adding of files is done by going through the file/dir list,
-  adding files per files, in a recursive way through the
-  directory. Each time a path need to be added/removed it is done
-  before writing the file header in the archive.
-
-Method : add($p_filelist)
-Description :
-  This method add the files / directories listed in $p_filelist at the
-  end of the existing archive. If the archive does not yet exists it
-  is created. 
-  The $p_filelist parameter can be an array of string, each string
-  representing a filename or a directory name with their path if
-  needed. It can also be a single string with names separated by a
-  single blank. 
-  See addModify() method for details and limitations.
-Arguments :
-  $p_filelist : An array of filenames and directory names, or a single
-  string with names separated by a single blank space. 
-Return value :
-  true on success, false on error.
-Sample 1 :
-  $tar_object = new Archive_Tar("tarname.tar");
-  [...]
-  $v_list[0]="dev/file.txt";
-  $v_list[1]="dev/data/"; (Optional '/' at the end)
-  $v_list[2]="log/file.log";
-  $tar_object->add($v_list);
-Sample 2 :
-  $tar_object = new Archive_Tar("tarname.tgz", true);
-  [...]
-  $v_list[0]="dev/file.txt";
-  $v_list[1]="dev/data/"; (Optional '/' at the end)
-  $v_list[2]="log/file.log";
-  $tar_object->add($v_list);
-How it works :
-  Simply call the addModify() method with the right parameters.
-
-Method : addString($p_filename, $p_string, $p_datetime, $p_params)
-Description :
-  This method add a single string as a file at the
-  end of the existing archive. If the archive does not yet exists it
-  is created.
-Arguments :
-  $p_filename : A string which contains the full filename path
-                that will be associated with the string.
-  $p_string :   The content of the file added in the archive.
-  $p_datetime : (Optional) Timestamp of the file (default = now)
-  $p_params :   (Optional) Various file metadata:
-                    stamp - As above, timestamp of the file
-                    mode - UNIX-style permissions (default 0600)
-                    type - Is this a regular file or link (see TAR
-                           format spec for how to create a hard/symlink)
-                    uid - UNIX-style user ID (default 0 = root)
-                    gid - UNIX-style group ID (default 0 = root)
-Return value :
-  true on success, false on error.
-Sample 1 :
-  $v_archive = & new Archive_Tar($p_filename);
-  $v_archive->setErrorHandling(PEAR_ERROR_PRINT);
-  $v_result = $v_archive->addString('data/test.txt', 'This is the text of the string');
-  $v_result = $v_archive->addString(
-                  'data/test.sh',
-                  "#!/bin/sh\necho 'Hello'",
-                  time(),
-                  array( "mode" => 0755, "uid" => 34 )
-              );
-
-
-Method : extract($p_path = "")
-Description :
-  This method extract all the content of the archive in the directory
-  indicated by $p_path.If $p_path is optional, if not set the archive
-  is extracted in the current directory. 
-  While extracting a file, if the directory path does not exists it is
-  created. 
-  See extractModify() for details and limitations.
-Arguments :
-  $p_path : Optional path where the files/dir need to by extracted.
-Return value :
-  true on success, false on error.
-Sample :
-  $tar_object = new Archive_Tar("tarname.tar");
-  $tar_object->extract();
-How it works :
-  Simply call the extractModify() method with appropriate parameters.
-
-Method : extractModify($p_path, $p_remove_path)
-Description :
-  This method extract all the content of the archive in the directory
-  indicated by $p_path. When relevant the memorized path of the
-  files/dir can be modified by removing the $p_remove_path path at the
-  beginning of the file/dir path. 
-  While extracting a file, if the directory path does not exists it is
-  created. 
-  While extracting a file, if the file already exists it is replaced
-  without looking for last modification date. 
-  While extracting a file, if the file already exists and is write
-  protected, the extraction is aborted. 
-  While extracting a file, if a directory with the same name already
-  exists, the extraction is aborted. 
-  While extracting a directory, if a file with the same name already
-  exists, the extraction is aborted. 
-  While extracting a file/directory if the destination directory exist
-  and is write protected, or does not exist but can not be created,
-  the extraction is aborted. 
-  If after extraction an extracted file does not show the correct
-  stored file size, the extraction is aborted. 
-  When the extraction is aborted, a PEAR error text is set and false
-  is returned. However the result can be a partial extraction that may
-  need to be manually cleaned. 
-Arguments :
-  $p_path : The path of the directory where the files/dir need to by
-            extracted. 
-  $p_remove_path : Part of the memorized path that can be removed if
-                   present at the beginning of the file/dir path. 
-Return value :
-  true on success, false on error.
-Sample :
-  // Imagine tarname.tar with files :
-  //   dev/data/file.txt
-  //   dev/data/log.txt
-  //   readme.txt
-  $tar_object = new Archive_Tar("tarname.tar");
-  $tar_object->extractModify("install", "dev");
-  // Files will be extracted there :
-  //   install/data/file.txt
-  //   install/data/log.txt
-  //   install/readme.txt
-How it works :
-  Open the archive and call a more generic function that can extract
-  only a part of the archive or all the archive. 
-  See extractList() method for more details.
-
-Method : extractInString($p_filename)
-Description :
-  This method extract from the archive one file identified by $p_filename.
-  The return value is a string with the file content, or NULL on error. 
-Arguments :
-  $p_filename : The path of the file to extract in a string. 
-Return value :
-  a string with the file content or NULL.
-Sample :
-  // Imagine tarname.tar with files :
-  //   dev/data/file.txt
-  //   dev/data/log.txt
-  //   dev/readme.txt
-  $v_archive = & new Archive_Tar('tarname.tar');
-  $v_archive->setErrorHandling(PEAR_ERROR_PRINT);
-  $v_string = $v_archive->extractInString('dev/readme.txt');
-  echo $v_string;
-
-Method : listContent()
-Description :
-  This method returns an array of arrays that describe each
-  file/directory present in the archive. 
-  The array is not sorted, so it show the position of the file in the
-  archive. 
-  The file informations are :
-    $file[filename] : Name and path of the file/dir.
-    $file[mode] : File permissions (result of fileperms())
-    $file[uid] : user id
-    $file[gid] : group id
-    $file[size] : filesize
-    $file[mtime] : Last modification time (result of filemtime())
-    $file[typeflag] : "" for file, "5" for directory
-Arguments :
-Return value :
-  An array of arrays or 0 on error.
-Sample :
-  $tar_object = new Archive_Tar("tarname.tar");
-  if (($v_list  =  $tar_object->listContent()) != 0)
-    for ($i=0; $i<sizeof($v_list); $i++)
-    {
-      echo "Filename :'".$v_list[$i][filename]."'<br>";
-      echo " .size :'".$v_list[$i][size]."'<br>";
-      echo " .mtime :'".$v_list[$i][mtime]."' (".
-           date("l dS of F Y h:i:s A", $v_list[$i][mtime]).")<br>";
-      echo " .mode :'".$v_list[$i][mode]."'<br>";
-      echo " .uid :'".$v_list[$i][uid]."'<br>";
-      echo " .gid :'".$v_list[$i][gid]."'<br>";
-      echo " .typeflag :'".$v_list[$i][typeflag]."'<br>";
-    }
-How it works :
-  Call the same function as an extract however with a flag to only go
-  through the archive without extracting the files. 
-
-Method : extractList($p_filelist, $p_path = "", $p_remove_path = "")
-Description :
-  This method extract from the archive only the files indicated in the
-  $p_filelist. These files are extracted in the current directory or
-  in the directory indicated by the optional $p_path parameter. 
-  If indicated the $p_remove_path can be used in the same way as it is
-  used in extractModify() method. 
-Arguments :
-  $p_filelist : An array of filenames and directory names, or a single
-                string with names separated by a single blank space. 
-  $p_path : The path of the directory where the files/dir need to by
-            extracted. 
-  $p_remove_path : Part of the memorized path that can be removed if
-                   present at the beginning of the file/dir path. 
-Return value :
-  true on success, false on error.
-Sample :
-  // Imagine tarname.tar with files :
-  //   dev/data/file.txt
-  //   dev/data/log.txt
-  //   readme.txt
-  $tar_object = new Archive_Tar("tarname.tar");
-  $tar_object->extractList("dev/data/file.txt readme.txt", "install",
-                           "dev");
-  // Files will be extracted there :
-  //   install/data/file.txt
-  //   install/readme.txt
-How it works :
-  Go through the archive and extract only the files present in the
-  list.

-Installs one or more PEAR packages.  You can specify a package to
-install in four ways:
-
-&quot;Package-1.0.tgz&quot; : installs from a local file
-
-&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&#039;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.

-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.

-Creates a PECL package from its package2.xml file.
-
-An automatic conversion will be made to a package.xml 1.0 and written out to
-disk in the current directory as &quot;package.xml&quot;.  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 or 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.

-An automatic conversion will be made to a package.xml 1.0 and written out to
-disk in the current directory as "package.xml".  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 or 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.

- * - remote files (downloadable urls)
- * - abstract package names
- *
- * The first two elements are handled cleanly by PEAR_PackageFile, but the third requires

- * format returned of dependencies is slightly different from that used in package.xml.
- *
- * This class hides the differences between these elements, and makes automatic
- * dependency resolution a piece of cake.  It also manages conflicts when
- * two classes depend on incompatible dependencies, or differing versions of the same
- * package dependency.  In addition, download will not be attempted if the php version is
- * not supported, PEAR installer version is not supported, or non-PECL extensions are not
- * installed.

-/**
- * A task is an operation that manipulates the contents of a file.
- *
- * Simple tasks operate on 1 file.  Multiple tasks are executed after all files have been
- * processed and installed, and are designed to operate on all files containing the task.
- * The Post-install script task simply takes advantage of the fact that it will be run
- * after installation, replace is a simple task.
- *
- * Combining tasks is possible, but ordering is significant.
- *
- * <file name="test.php" role="php">
- *  <tasks:replace from="@data-dir@" to="data_dir" type="pear-config"/>
- *  <tasks:postinstallscript/>
- * </file>
- *
- * This will first replace any instance of @data-dir@ in the test.php file
- * with the path to the current data directory.  Then, it will include the
- * test.php file and run the script it contains to configure the package post-installation.

-/**
- * 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

-/**
- * 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;
- *  }

-=========================
-Installing the PEAR Installer.
-
-You should install PEAR on a local development machine first.  Installing
-PEAR on a remote production machine should only be done after you are
-familiar with PEAR and have tested code using PEAR on your development
-machine.
-
-There are two methods of installing PEAR
- - PEAR bundled in PHP
- - go-pear
-
-We will first examine how to install PEAR that is bundled with PHP.
-
-Microsoft Windows
-=================
-If you are running PHP 5.2.0 or newer, simply download and
-run the windows installer (.msi) and PEAR can be automatically
-installed.
-
-Otherwise, for older PHP versions, download the .zip of windows,
-there is a script included with your PHP distribution that is called
-"go-pear".  You must open a command box in order to run it.  Click
-"start" then click "Run..." and type "cmd.exe" to open a command box.
-Use "cd" to change directory to the location of PHP where you unzipped it,
-and run the go-pear command.
-
-Unix
-====
-When compiling PHP from source, you simply need to include the
---with-pear directive on the "./configure" command.  This is "on"
-by default in most PHP versions, but it doesn't hurt to list it
-explicitly.  You should also consider enabling the zlib extension via
---enable-zlib, so that the PEAR installer will be able to handle gzipped
-files (i.e. smaller package files for faster downloads).  Later, when you
-run "make install" to install PHP itself, part of the process will be
-prompts that ask you where you want PEAR to be installed.
-
-go-pear
-=======
-For users who cannot perform the above steps, or who wish to obtain the
-latest PEAR with a slightly higher risk of failure, use go-pear.  go-pear
-is obtained by downloading http://pear.php.net/go-pear and saving it as go-pear.php.
-After downloading, simply run "php go-pear.php" or open it in a web browser
-(windows only) to download and install PEAR.
-
-You can always ask general installation questions on pear-general@lists.php.net,
-a public mailing list devoted to support for PEAR packages and installation-
-related issues.
-
-Happy PHPing, we hope PEAR will be a great tool for your development work!

-/**
- * Base class for other PEAR classes.  Provides rudimentary
- * emulation of destructors.
- *
- * 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;

-=========================
-
-What is the PEAR Installer? What is PEAR?
-------------------------------------------
-PEAR is the PHP Extension and Application Repository, found at
-http://pear.php.net.
-
-The **PEAR Installer** is this software, which contains executable
-files and PHP code that is used to **download and install** PEAR code
-from pear.php.net.
-
-PEAR contains useful **software libraries and applications** such as
-MDB2 (database abstraction), HTML_QuickForm (HTML forms management),
-PhpDocumentor (auto-documentation generator), DB_DataObject
-(Data Access Abstraction), and many hundreds more.
-Browse all available packages at http://pear.php.net, the list is
-constantly growing and updating to reflect improvements in the PHP language.
-
-.. warning::
-  Do not run PEAR without installing it - if you downloaded this
-  tarball manually, you MUST install it.  Read the instructions in INSTALL
-  prior to use.
-
-
-Documentation
--------------
-Documentation for PEAR can be found at http://pear.php.net/manual/.
-Installation documentation can be found in the INSTALL file included
-in this tarball.
-
-
-Tests
------
-Run the tests without installation as follows::
-
-  $ ./scripts/pear.sh run-tests -r tests
-
-You should have the ``Text_Diff`` package installed to get nicer error output.
-
-Happy PHPing, we hope PEAR will be a great tool for your development work!

-*
-* In case you need to to pass file names with spaces,

-/**
- * Base class for other PEAR classes.  Provides rudimentary
- * emulation of destructors.
- *
- * 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;

-/**
- * 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().

-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.

-Installs one or more PEAR packages.  You can specify a package to
-install in four ways:
-
-&quot;Package-1.0.tgz&quot; : installs from a local file
-
-&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&#039;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.

-     *                that should be used for all output

-     *  '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,

-     *                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)

- * not supported, PEAR installer version is not supported, or non-PECL extensions are not
- * installed.

-/**
- * 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

-  <title>Introduction</title>
-  <para>
-  Structures_Graph is a package for creating and manipulating graph datastructures. A graph is a set of objects, called nodes, connected by arcs. When used as a datastructure, usually nodes contain data, and arcs represent relationships between nodes. When arcs have a direction, and can be travelled only one way, graphs are said to be directed. When arcs have no direction, and can always be travelled both ways, graphs are said to be non directed.
-  </para>
-  <para>
-  Structures_Graph provides an object oriented API to create and directly query a graph, as well as a set of Manipulator classes to extract information from the graph.
-  </para>
- </refsect1>
- <refsect1 id="{@id package.database.structures_graph.tutorial.creation}">
-  <title>Creating a Graph</title>
-  <para>
-   Creating a graph is done using the simple constructor:
-   <programlisting>
-    <![CDATA[
-require_once 'Structures/Graph.php';
-
-$directedGraph =& new Structures_Graph(true);
-$nonDirectedGraph =& new Structures_Graph(false);
-    ]]>
-   </programlisting>
-   and passing the constructor a flag telling it whether the graph should be directed. A directed graph will always be directed during its lifetime. It's a permanent characteristic.
-  </para>
-  <para>
-  To fill out the graph, we'll need to create some nodes, and then call Graph::addNode.
-   <programlisting>
-    <![CDATA[
-require_once 'Structures/Graph/Node.php';
-
-$nodeOne =& new Structures_Graph_Node();
-$nodeTwo =& new Structures_Graph_Node();
-$nodeThree =& new Structures_Graph_Node();
-
-$directedGraph->addNode(&$nodeOne);
-$directedGraph->addNode(&$nodeTwo);
-$directedGraph->addNode(&$nodeThree);
-    ]]>
-   </programlisting>
-   and then setup the arcs:
-   <programlisting>
-    <![CDATA[
-$nodeOne->connectTo($nodeTwo);
-$nodeOne->connectTo($nodeThree);
-    ]]>
-   </programlisting>
-   Note that arcs can only be created after the nodes have been inserted into the graph. 
-  </para>
- </refsect1>
- <refsect1 id="{@id package.database.structures_graph.tutorial.nodesanddata}">
-  <title>Associating Data</title>
-  <para>
-  Graphs are only useful as datastructures if they can hold data. Structure_Graph stores data in nodes. Each node contains a setter and a getter for its data.
-   <programlisting>
-    <![CDATA[
-$nodeOne->setData("Node One's Data is a String");
-$nodeTwo->setData(1976);
-$nodeThree->setData('Some other string');
-
-print("NodeTwo's Data is an integer: " . $nodeTwo->getData());
-    ]]>
-   </programlisting>
-  </para>
-  <para>
-  Structure_Graph nodes can also store metadata, alongside with the main data. Metadata differs from regular data just because it is stored under a key, making it possible to store more than one data reference per node. The metadata getter and setter need the key to perform the operation:
-   <programlisting>
-    <![CDATA[
-$nodeOne->setMetadata('example key', "Node One's Sample Metadata");
-print("Metadata stored under key 'example key' in node one: " . $nodeOne->getMetadata('example key'));
-$nodeOne->unsetMetadata('example key');
-    ]]>
-   </programlisting>
-  </para>
- </refsect1>
- <refsect1 id="{@id package.database.structures_graph.tutorial.querying}">
-  <title>Querying a Graph</title>
-  <para>
-  Structures_Graph provides for basic querying of the graph:
-   <programlisting>
-    <![CDATA[
-// Nodes are able to calculate their indegree and outdegree
-print("NodeOne's inDegree: " . $nodeOne->inDegree());
-print("NodeOne's outDegree: " . $nodeOne->outDegree());
-
-// and naturally, nodes can report on their arcs
-$arcs = $nodeOne->getNeighbours();
-for ($i=0;$i<sizeof($arcs);$i++) {
-    print("NodeOne has an arc to " . $arcs[$i]->getData());
-}
-    ]]>
-   </programlisting>
-  </para>
- </refsect1>
-</refentry>

-                       Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-
-  This version of the GNU Lesser General Public License incorporates
-the terms and conditions of version 3 of the GNU General Public
-License, supplemented by the additional permissions listed below.
-
-  0. Additional Definitions.
-
-  As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the GNU
-General Public License.
-
-  "The Library" refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-
-  An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
-  A "Combined Work" is a work produced by combining or linking an
-Application with the Library.  The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
-  The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
-  The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
-  1. Exception to Section 3 of the GNU GPL.
-
-  You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
-  2. Conveying Modified Versions.
-
-  If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
-   a) under this License, provided that you make a good faith effort to
-   ensure that, in the event an Application does not supply the
-   function or data, the facility still operates, and performs
-   whatever part of its purpose remains meaningful, or
-
-   b) under the GNU GPL, with none of the additional permissions of
-   this License applicable to that copy.
-
-  3. Object Code Incorporating Material from Library Header Files.
-
-  The object code form of an Application may incorporate material from
-a header file that is part of the Library.  You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
-   a) Give prominent notice with each copy of the object code that the
-   Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the object code with a copy of the GNU GPL and this license
-   document.
-
-  4. Combined Works.
-
-  You may convey a Combined Work under terms of your choice that,
-taken together, effectively do not restrict modification of the
-portions of the Library contained in the Combined Work and reverse
-engineering for debugging such modifications, if you also do each of
-the following:
-
-   a) Give prominent notice with each copy of the Combined Work that
-   the Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the Combined Work with a copy of the GNU GPL and this license
-   document.
-
-   c) For a Combined Work that displays copyright notices during
-   execution, include the copyright notice for the Library among
-   these notices, as well as a reference directing the user to the
-   copies of the GNU GPL and this license document.
-
-   d) Do one of the following:
-
-       0) Convey the Minimal Corresponding Source under the terms of this
-       License, and the Corresponding Application Code in a form
-       suitable for, and under terms that permit, the user to
-       recombine or relink the Application with a modified version of
-       the Linked Version to produce a modified Combined Work, in the
-       manner specified by section 6 of the GNU GPL for conveying
-       Corresponding Source.
-
-       1) Use a suitable shared library mechanism for linking with the
-       Library.  A suitable mechanism is one that (a) uses at run time
-       a copy of the Library already present on the user's computer
-       system, and (b) will operate properly with a modified version
-       of the Library that is interface-compatible with the Linked
-       Version.
-
-   e) Provide Installation Information, but only if you would otherwise
-   be required to provide such information under section 6 of the
-   GNU GPL, and only to the extent that such information is
-   necessary to install and execute a modified version of the
-   Combined Work produced by recombining or relinking the
-   Application with a modified version of the Linked Version. (If
-   you use option 4d0, the Installation Information must accompany
-   the Minimal Corresponding Source and Corresponding Application
-   Code. If you use option 4d1, you must provide the Installation
-   Information in the manner specified by section 6 of the GNU GPL
-   for conveying Corresponding Source.)
-
-  5. Combined Libraries.
-
-  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 that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
-   a) Accompany the combined library with a copy of the same work based
-   on the Library, uncombined with any other library facilities,
-   conveyed under the terms of this License.
-
-   b) Give prominent notice with the combined library that part of it
-   is a work based on the Library, and explaining where to find the
-   accompanying uncombined form of the same work.
-
-  6. Revised Versions of the GNU Lesser General Public License.
-
-  The Free Software Foundation may publish revised and/or new versions
-of the GNU 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 as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
-  If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

-* 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));
