Detailed Description

Class for the manipulation of a gzipped tar archive (tar.gz)

Copyright (c) 2007, Itay Perl, Canorus development team All Rights Reserved. See AUTHORS for a complete list of authors.

Licensed under the GNU GENERAL PUBLIC LICENSE. See LICENSE.GPL for details.

This class allows read/write operations on tar.gz archives.

Warning

This is not a CATar subclass as it does not represent a tar file, but a gzipped file. The uncompressed content is a tar file.

See RFC 1952 for the GZIP specification.
