TAR/GZIP/BZIP2/ZIP Archives is a class for
manipulating tar, gzip, bzip2, zip, and
self-extracting zip archives. It is capable of
recursing through and storing a directory
structure and creating archives in memory or on
disk, and can allow the client to download the
created archive directly from memory. Zip file
comments are supported. It supports symbolic links
where applicable, and archived files are
automatically sorted within the archive for
greater compression in gzip and bzip2 archives.
