- // Presentation :
- // PclTar is a library that allow you to create a GNU TAR + GNU ZIP archive,
- // to add files or directories, to extract all the archive or a part of it.
- // So far tests show that the files generated by PclTar are readable by
- // gzip tools and WinZip application.

- // See readme.txt (English & Fran�ais) and http://www.phpconcept.net

- // 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
- // this software the author can not be responsible.
- // The use of this software is at the risk of the user.

- // Creates a new archive with name $p_tarname containing the files and/or
- // directories indicated in $p_list. If the tar filename extension is
- // ".tar", the file will not be compressed. If it is ".tar.gz" or ".tgz"
- // it will be a gzip compressed tar archive.
- // If you want to use an other extension, you must indicate the mode in
- // $p_mode ("tar" or "tgz").
- // $p_add_dir and $p_remove_dir give you the ability to store a path
- // 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).
