// PclTar is a library that allow you to create a GNU TAR + GNU ZIP archive,

// So far tests show that the files generated by PclTar are readable by
// gzip tools and WinZip application.
//
// Description :

//
// Warning :
// This library and the associated files are non commercial, non professional
// work.
// It should not have unexpected results. However if any damage is caused by

// Creates a new archive with name $p_tarname containing the files and/or

// $p_mode ("tar" or "tgz").

// which is not the real path of the files.
// Parameters :
// $p_tarname : Name of an existing tar file
// $p_filelist : An array containing file or directory names, or
// a string containing one filename or directory name, or
// a string containing a list of filenames and/or directory
// names separated by spaces.
// $p_mode : "tar" for normal tar archive, "tgz" for gzipped tar archive,
// if $p_mode is not specified, it will be determined by the extension.
// $p_add_dir : Path to add in the filename path archived
// $p_remove_dir : Path to remove in the filename path archived
// Return Values :
// 1 on success, or an error code (see table at the beginning).

// PclZip is the class that represent a Zip archive.
// The public methods allow the manipulation of the archive.
// Attributes :
// Attributes must not be accessed directly.
// Methods :
// PclZip() : Object creator
// create() : Creates the Zip archive
// listContent() : List the content of the Zip archive
// extract() : Extract the content of the archive
// properties() : List the properties of the archive

// This method supports two different synopsis. The first one is historical.
// This method creates a Zip Archive. The Zip file is created in the

// are added in the archive. See the parameters description for the
// supported format of $p_filelist.
// When a directory is in the list, the directory and its content is added
// in the archive.
// In this synopsis, the function takes an optional variable list of
// options. See bellow the supported options.
// Parameters :
// $p_filelist : An array containing file or directory names, or
// a string containing one filename or one directory name, or
// a string containing a list of filenames and/or directory
// names separated by spaces.
// $p_add_dir : A path to add before the real path of the archived file,
// in order to have it memorized in the archive.
// $p_remove_dir : A path to remove from the real path of the file to archive,
// in order to have a shorter path memorized in the archive.
// When $p_add_dir and $p_remove_dir are set, $p_remove_dir
// is removed first, before $p_add_dir is added.

// status : status of the action (depending of the action) :
// Values are :
// ok : OK !
// filtered : the file / dir is not extracted (filtered by user)
// already_a_directory : the file can not be extracted because a
