-/**
- * Those constants represent the compression method to use.
- * COMPRESS_GZIP is used for the GZIP compression; COMPRESS_BZIP for
- * BZIP2 and COMPRESS_NONE for no compression.
- *
- * On the other hand, COMPRESS_AUTO is a bit harder. It will first check
- * if the zlib extensions are loaded.
- * If it is, GZIP will be used. Else it will check if the bz2 extensions
- * are loaded. If it is, BZIP2 will be used. Else no compression will be
- * performed.
- *
- * You can then use getCompression() to know the compression chosen.
- *
- * If you selected a compression which can't be used (i.e extension not
- * present), it will be just disabled, and won't produce any error !
- * As a consequence, getCompression() will return COMPRESS_NONE
- *
- * ARCHIVE_DYNAMIC can be passed as the first argument of the constructor, to
- * create an archive in memory instead of a file. See also: MaxgTar(),
- * getDynamicArchive() and writeArchive()
- *
- * ARCHIVE_RENAMECOMP is a flag that can be multiplied by the compression method
- * (i.e COMPRESS_AUTO * ARCHIVE_RENAMECOMP). This will add the correct extension
- * to the archive name, which is useful with COMPRESS_AUTO, ie .bz2 if you gave
- * COMPRESS_BZIP. See also getCompression(TRUE) which does exactly the
- * same
- *
- * COMPRESS_DETECT does exactly the opposite and try to detect the
- * compression to use to read the archive depending on its extension. (i.e if
- * the archive ends with .tar.gz TarLib will try to decompress it with
- * GZIP). See also setCompression()
- *
- * FULL_ARCHIVE is a -1 constant that means "the complete archive" when
- * extracting. This is explained in Extract()

-     * (ie https://host.dom/archive.tar.gz), but for reading only and if the
-     * directive allow_url_fopen is enabled in PHP.INI (this can be checked with
-     * TarInfo()). If you pass a file that doesn't exist, the script
-     * will try to create it. If the archive already exists and contains files,
-     * you can use Add() to append files.But by default this parameter
-     * is ARCHIVE_DYNAMIC (write only) so the archive is created in memory and
-     * can be sent to a file [writeArchive()] or to the client
-     * [sendClient()]
-     *
-     * compression_type should be a constant that represents a type of
-     * compression, or its integer value. The different values are described in
-     * the constants.
-     *
-     * compression_level is an integer between 1 and 9 (by default) an
-     * represent the GZIP or BZIP compression level.  1 produce fast compression,
-     * and 9 produce smaller files. See the RFC 1952 for more infos.
