• Log::Log4perl – Log4j implementation for Perl – metacpan.org
• Log::Log4perl::Config – Log4perl configuration file syntax – metacpan.org – everything about the configuration file syntax, includes a “cookbook”
• the initial article on Log::Log4perl at perl.com [link], and the errata [link]
• Michael Schilli at github and esp. his Log4perl [link]

its ancestor log4j:

• “Short introduction to log4j” by Ceki Gülcü, March 2002 [the proper link]
• log4j‘s wikipedia [link] with a nice and terse description
• Vipan Singla’s article “Don’t Use System.out.println! Use Log4j” [link]

Log::Log4perl lets you remote-control and fine-tune the logging behaviour of your system from the outside. It implements the widely popular (Java-based) Log4j logging package in pure Perl.

Log4perl is also compatible with log4j’s graphical log analyser Chainsaw.

Test::Simple and Test::More have proven to be popular testing modules, but they’re not always flexible enough. Test::Builder provides a building block upon which to write your own test libraries which can work together.

IO::Compress::Zip – Write zip files/buffers – metacpan.org

I found code, that makes use of this module. The 1st problem, I had to deal with: the file to be written into the ZIP archive and the ZIP archive both get named using absolute pathnames. That’s alright for the ZIP archive, but you usually don’t like archive members with absolute pathnames. The manual page describes, which feature deals with this (“FilterName”), and it also gives a nice and short recipe.

Cvs – Object oriented interface to the CVS command – metacpan.org

It also has a nice module_list method. I would love to know, how to that on the command line outside this module.
