 * Base class for other PEAR classes.  Provides rudimentary

 *
 * 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.

When upgrading, your package will be updated if the provided new
package has a higher version number (use the -f option if you need to
upgrade anyway).

More than one package may be specified at once.

  <doc>[channel/]&lt;package&gt; ...
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.

     * callback types are:
     *
     *  'setup'       called at the very beginning, parameter is a UI object
     *                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.
     *                Note that $save_dir will not be affected by this, only
     *                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 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
     * setting), the proxy will be used.
     *

     * Download a file through HTTP.  Considers suggested file name in
     * Content-disposition: header and can run a callback function for
     * different events.  The callback will be called with two
     * parameters: the callback type, and parameters.  The implemented
     * callback types are:
     *
     *  'setup'       called at the very beginning, parameter is a UI object
     *                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.
     *                Note that $save_dir will not be affected by this, only
     *                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
     * setting), the proxy will be used.
     *
     * @param string  $url       the URL to download
     * @param object  $ui        PEAR_Frontend_* instance
     * @param object  $config    PEAR_Config instance
     * @param string  $save_dir  directory to save file in
     * @param mixed   $callback  function/method to call for status
     *                           updates

     * @param false|array $accept Accept headers to send
     * @param false|string $channel Channel to use for retrieving authentication
     * @return mixed  Returns the full path of the downloaded file or a PEAR
     *                error on failure.  If the error is caused by
     *                socket-related errors, the error object will
     *                have the fsockopen error code available through
     *                getCode().  If caching is requested, then return the header
     *                values.
     *                If $lastmodified was given and the there are no changes,
     *                boolean false is returned.

/**
 * 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

===================================
Last update : 2001-08-15



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");


Public arguments :
------------------

None


Public Methods :
----------------

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.

     * arguments without the leading reference to the running program.

     * option letters can be followed by a colon ':' to specify that the option
     * requires an argument, or a double colon '::' to specify that the option
     * takes an optional argument.

     * option argument should be followed by '=='.

to migrate over to one of the alternatives that have ben provided:
* PEAR_Common-&gt;downloadHttp (use PEAR_Downloader-&gt;downloadHttp instead)
* PEAR_Common-&gt;infoFromTgzFile (use PEAR_PackageFile-&gt;fromTgzFile instead)
* PEAR_Common-&gt;infoFromDescriptionFile (use PEAR_PackageFile-&gt;fromPackageFile instead)
* PEAR_Common-&gt;infoFromString (use PEAR_PackageFile-&gt;fromXmlstring instead)
* PEAR_Common-&gt;infoFromArray (use PEAR_PackageFile-&gt;fromAnyFile instead)
* PEAR_Common-&gt;xmlFromInfo (use a PEAR_PackageFile_v* object&apos;s generator instead)
* PEAR_Common-&gt;validatePackageInfo (use the validation of PEAR_PackageFile objects)
* PEAR_Common-&gt;analyzeSourceCode (use a PEAR_PackageFile_v* object instead)
* PEAR_Common-&gt;detectDependencies (use PEAR_Downloader_Package-&gt;detectDependencies instead)
* PEAR_Common-&gt;buildProvidesArray (use PEAR_PackageFile_v1-&gt;_buildProvidesArray or
  PEAR_PackageFile_v2_Validator-&gt;_buildProvidesArray)

PHP 4.4 and 5.1.6 are now the minimum PHP requirements, for brave souls
pear upgrade -f PEAR will allow people with lower versions
to upgrade to this release but no guarantees will be made that it will work properly.

Support for XML RPC channels has been dropped - The only ones that used it
(pear.php.net and pecl.php.net) have used the REST interface for years now.
SOAP support also removed as it was only proof of concept.

  NOTE!
  Functions that have been deprecated for 3+ years in PEAR_Common, please take a moment
  to migrate over to one of the alternatives that have ben provided:
  * PEAR_Common-&gt;downloadHttp (use PEAR_Downloader-&gt;downloadHttp instead)
  * PEAR_Common-&gt;infoFromTgzFile (use PEAR_PackageFile-&gt;fromTgzFile instead)
  * PEAR_Common-&gt;infoFromDescriptionFile (use PEAR_PackageFile-&gt;fromPackageFile instead)
  * PEAR_Common-&gt;infoFromString (use PEAR_PackageFile-&gt;fromXmlstring instead)
  * PEAR_Common-&gt;infoFromArray (use PEAR_PackageFile-&gt;fromAnyFile instead)
  * PEAR_Common-&gt;xmlFromInfo (use a PEAR_PackageFile_v* object&apos;s generator instead)
  * PEAR_Common-&gt;validatePackageInfo (use the validation of PEAR_PackageFile objects)
  * PEAR_Common-&gt;analyzeSourceCode (use a PEAR_PackageFile_v* object instead)
  * PEAR_Common-&gt;detectDependencies (use PEAR_Downloader_Package-&gt;detectDependencies instead)
  * PEAR_Common-&gt;buildProvidesArray (use PEAR_PackageFile_v1-&gt;_buildProvidesArray or
    PEAR_PackageFile_v2_Validator-&gt;_buildProvidesArray)

  PHP 4.4 and 5.1.6 are now the minimum PHP requirements, for brave souls
  pear upgrade -f PEAR will allow people with lower versions
  to upgrade to this release but no guarantees will be made that it will work properly.

  Support for XML RPC channels has been dropped - The only ones that used it
  (pear.php.net and pecl.php.net) have used the REST interface for years now.
  SOAP support also removed as it was only proof of concept.

  Move codebase from the PHP License to New BSD 2 clause license

  <doc>[channel/]&lt;package&gt; ...
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.

Upgrades one or more PEAR packages.  See documentation for the
"install" command for ways to specify a package.

When upgrading, your package will be updated if the provided new
package has a higher version number (use the -f option if you need to
upgrade anyway).

More than one package may be specified at once.

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.

/**
 * Coordinates download parameters and manages their dependencies
 * prior to downloading them.
 *
 * Input can come from three sources:
 *
 * - local files (archives or package.xml)
 * - remote files (downloadable urls)
 * - abstract package names
 *
 * The first two elements are handled cleanly by PEAR_PackageFile, but the third requires
 * accessing pearweb's xml-rpc interface to determine necessary dependencies, and the
 * 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.

/**
 * 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().

     *                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

/**
 * 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!

 * 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 - The PEAR Installer
*************************
.. image:: https://travis-ci.org/pear/pear-core.svg?branch=stable
    :target: https://travis-ci.org/pear/pear-core

=========================================
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.

To run the tests with another PHP version, modify ``php_bin`` and set the
``PHP_PEAR_PHP_BIN`` environment variable::

  $ pear config-set php_bin /usr/local/bin/php7
  $ PHP_PEAR_PHP_BIN=/usr/local/bin/php7 ./scripts/pear.sh run-tests -r tests

Happy PHPing, we hope PEAR will be a great tool for your development work!


Test dependencies
=================
* ``zlib``


=========
Releasing
=========
Create a PEAR package as well as phars for pear-less installation::

    $ rm -f PEAR-*.tgz
    $ pear package package2.xml
    $ cd go-pear-tarballs
    $ rm -f PEAR-*
    $ cp ../PEAR-*.tgz .
    $ gunzip PEAR-*.tgz
    $ pear download -Z Archive_Tar Console_Getopt Structures_Graph XML_Util
    $ mkdir src && cd src
    $ for i in ../*.tar; do tar xvf $i; done
    $ mv *\/* .
    $ cd ../../
    $ php make-gopear-phar.php
    $ php make-installpear-nozlib-phar.php

(Or simply run ``build-release.sh``).

``go-pear.phar`` is contains the PEAR installer installer that asks questions
where to install it.
It is available from http://pear.php.net/go-pear.phar.

``install-pear-nozlib.phar`` installs PEAR automatically without asking
anything.
It is shipped with PHP itself.

  <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.

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