Title Page Software Version Description for Tie::Gzip - gzip and gunzip with a small memory footprint Revision: - Version: 0.01 Date: 2003/09/12 Prepared for: General Public Prepared by: SoftwareDiamonds.com Esupport@SoftwareDiamonds.comE Copyright: copyright © 2003 Software Diamonds Classification: NONE 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. 1.2 System overview The 'Tie::Gzip' module provides a file handle Tie for compressing and uncompressing files using the gzip format. By tieing a filehandle to 'Tie::Gzip' subsequent uses of the file subroutines with the tied filehandle will compress data written to an opened file using gzip compression and decompress data read from an opened file using gzip compression. If the 'Tie::Gzip' tie receives a *filename* or *mode filename* after completing the tie, 'Tie::Gzip' will open *filename*. During the tie, Tie::Gzip will first try to load the 'Compress::Zlib' module and package. If successful, 'Tie::Gzip' uses the 'Compress::Zlib' for compressing and decompressing the file data. If unsuccessful, 'Tie::Gzip' setups up the following pipes to an anticipated GNU 'gzip' site command for compressing and decompressing the file data: gzip --decompress --stdout {} | # read file data | gzip --stdout > {} # write file data where the string '{}' is a placeholder for the *filename*. 1.3 Document overview. This document releases Tie::Gzip version 0.01 providing a description of the inventory, installation instructions and other information necessary to utilize and track this release. 3.0 VERSION DESCRIPTION All file specifications in this SVD use the Unix operating system file specification. 3.1 Inventory of materials released.
