The PCP::PMDA Perl module contains the language bindings for building Performance Metric Domain Agents (PMDAs) using Perl. Each PMDA exports performance data for one specific domain, for example the operating system kernel, Cisco routers, a database, an application, etc.
This module allows you to reuse PDF-files. You can use pages, images, fonts and Acrobat JavaScript from old PDF-files (if they were not encrypted), and rearrange the components, and add new graphics, texts etc. There is also support for graphics. In the tutorial there is a description of how to transform simple PDF-pages to graphic Perl objects with the help of programs based on this module. The module is fairly fast, so it should be possible to use it for mass production.
Perl::Critic is an extensible framework for creating and applying coding standards to Perl source code. Essentially, it is a static source code analysis engine. Perl::Critic is distributed with a number of Perl::Critic::Policy modules that attempt to enforce various coding guidelines. Most Policy modules are based on Damian Conway's book Perl Best Practices. However, Perl::Critic is not limited to PBP and will even support Policies that contradict Conway. You can enable, disable, and customize those Polices through the Perl::Critic interface. You can also create new Policy modules that suit your own tastes.
This module allows you to change perl's internal destruction level. The default value of the destruct level is 0; it means that perl won't bother destroying all of its internal data structures and lets the OS do the cleanup for it at exit. For perls built with debugging support (-DDEBUGGING), an environment variable PERL_DESTRUCT_LEVEL allows you to control the destruction level. This module enables you to modify it on non-debugging perls too. Note that some embedded environments might extend the meaning of the destruction level for their own purposes: mod_perl does that, for example.

Modules that provide OS-specific behaviors often need to know if the current operating system matches a more generic type of operating systems. For example, 'linux' is a type of 'Unix' operating system and so is 'freebsd'. This module provides a mapping between an operating system name as given by $^O and a more generic type. The initial version is based on the OS type mappings provided in Module::Build and ExtUtils::CBuilder (thus, Microsoft operating systems are given the type 'Windows' rather than 'Win32').
