DESCRIPTION

This distribution provides a Perl interface to allow reading and writing of compressed data created with the zlib and bzip2.

IO-Compress supports reading and writing of the following compressed data formats

bzip2
RFC 1950
RFC 1951
RFC 1952 (i.e. gzip)
zip

There are a number of companion modules for IO-Compress that extend the suite of compression formats available.

IO-Compress-Zstd
Adds support for zstd (Zstandard).
IO-Compress-Lzma
Adds support for lzma, xz and lzip.
IO-Compress-Lzf
Adds support for lzf.
IO-Compress-Lzop
Adds support for lzop.

Note that the following modules used to be distributed separately, but are now included with the IO-Compress distribution.

Compress-Zlib
IO-Compress-Zlib
IO-Compress-Bzip2
IO-Compress-Base

PREREQUISITES

Before you can build IO-Compress you need to have the following installed on your system:

FEEDBACK

How to report a problem with IO-Compress.

To help me help you, I need all of the following information:

The Versions of everything relevant. This includes:

a. The complete output from running this

    perl -V

Do not edit the output in any way.
Note, I want you to run "perl -V" and NOT "perl -v".

If your perl does not understand the "-V" option it is too
old. This module needs Perl version 5.004 or better.

b. The version of IO-Compress you have. If you have successfully installed IO-Compress, this one-liner will tell you:

   perl -MIO::Compress::Gzip -e 'print qq[ver $IO::Compress::Gzip::VERSION\n]'

If you are  running windows use this

   perl -MIO::Compress::Gzip -e "print qq[ver $IO::Compress::Gzip::VERSION\n]"

If you haven't installed IO-Compress then search IO::Compress::Gzip.pm
for a line like this:

  $VERSION = "2.213" ;

If you are having problems building IO-Compress, send me a complete log of what happened. Start by unpacking the IO-Compress module into a fresh directory and keep a log of all the steps, including the setting of configuration environment variables (if applicable).
```
[edit config.in or set environment varialbes, if necessary]
