- Name:
- tar Class
-
- Author:
- Josh Barger <joshb@npt.com>
-
- Description:
- This class reads and writes Tape-Archive (TAR) Files and Gzip
- compressed TAR files, which are mainly used on UNIX systems.
- This class works on both windows AND unix systems, and does
- NOT rely on external applications!! Woohoo!

-
- Version History:
- 1.0 04/10/2002 - InitialRelease
-
- 2.0 04/11/2002 - Merged both tarReader and tarWriter
- classes into one
- - Added support for gzipped tar files
- Remember to name for .tar.gz or .tgz
- if you use gzip compression!
- :: THIS REQUIRES ZLIB EXTENSION ::
- - Added additional comments to
- functions to help users
- - Added ability to remove files and
- directories from archive
- 2.1 04/12/2002 - Fixed serious bug in generating tar
- - Created another example file
- - Added check to make sure ZLIB is
- installed before running GZIP
- compression on TAR
- 2.2 05/07/2002 - Added automatic detection of Gzipped
- tar files (Thanks go to J?gen Falch
- for the idea)
- - Changed "private" functions to have
- special function names beginning with
- two underscores
