-/**
- * 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()

- * The constructor initialize the variables and prepare the class for the
- * archive, and return the object created. Note that you can use multiple
- * instances of the MaxgTar class, if you call this function another time and
- * store the object in an other variable.
- *
- * In fact, MaxgTar accepts the following arguments (all are optional) :
- *
- * filename can be either a file name (absolute or relative). In this
- * case, it can be used both for reading and writing. You can also open
- * remote archive if you add a protocole name at the beginning of the file
- * (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.

- * In this case the file are read from the webserver filesystem and the

- * - The more useful usage is to pass bidimensional arrays, where the

- * contents. You can even add empty folders to the package if the filename
- * has a leading '/'. Once again, have a look at the exemples to understand
- * better.
- *
- * Note you can also give arrays with both dynamic contents and static files.
- *
- * The optional parameter RemovePath can be used to delete a part of the tree
- * of the filename you're adding, for instance if you're adding in the root
- * of a package a file that is stored somewhere in the server tree.
- *
- * On the contrary the parameter AddPath can be used to add a prefix folder
