| // Presentation : |
| // PclZip is a PHP library that manage ZIP archives. |
| // So far tests show that archives generated by PclZip are readable by |
| // WinZip application and other tools. |
| // |
| // Description : |
| // See readme.txt 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. |

| // ----- File list separator |
| // In version 1.x of PclZip, the separator for file list is a space |
| // (which is not a very smart choice, specifically for windows paths !). |
| // A better separator should be a comma (,). This constant gives you the |
| // abilty to change that. |
| // However notice that changing this value, may have impact on existing |
| // scripts, using space separated filenames. |
| // Recommanded values for compatibility with older versions : |
| //define( 'PCLZIP_SEPARATOR', ' ' ); |

| // memory_limit of PHP and apply a ratio. |
| // threshold = memory_limit * ratio. |

| // $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 |
