1.0 SCOPE

This paragraph identifies and provides an overview of the released files.

1.1 Identification

This release, identified in 3.2, is a collection of Perl modules that extend the capabilities of the Perl language.

The Archive::TarGzip module provides tar subroutine to archive a list of files in an archive file in the tar format. The archve file may be optionally compressed using the gzip compression routines. The ARchive::TarGzip module also provides a untar subroutine that can extract the files from the tar or tar/gzip archive files.

The tar and untar top level subroutines use methods from the Archive::TarGzip class. The Archive::TarGzip class is dervided from its parent Archive::Tar class. The new methods supplied with the Archive::TarGzip derived class provide means to access individual files within the archive file without bringing the entire archive file into memory. When the gzip compression option is active, the compression is performed on the fly without creating an intermediate uncompressed tar file. The new methods provide a smaller memory footprint that enhances performance for very large archive files.

3.3 Changes

Changes are as follows

Archive::TarGzip-0.01

Originated

Archive::TarGzip-0.02

Outsource the gzip compression to Tie::Gzip.

Archive::TarGzip-0.03

The lastest build of Test::STDmaker expects the test library in the same directory as the test script. Coordiated with the lastest Test::STDmaker by moving the test library from tlib to t/Archive, the same directory as the test script and deleting the test library File::TestPath program module.
