This is Debian GNU/Linux's prepackaged version of Compress::Zlib (renamed to be libcompress-zlib-perl), the Perl module for creation and manipulation of gzip files. Michael Alan Dorman assembled this package. The library is available from the Comprehensive Perl Archive Network (CPAN). Visit to find a CPAN site near you. Upstream URL: http://search.cpan.org/dist/Compress-Zlib/ The only change for the Debian package was the addition of the debian/ files and the modification of the examples to reference /usr/bin/perl.
