System::Command is a class that launches external system commands and return an object representing them, allowing to interact with them through their STDIN, STDOUT and STDERR handles.

Term::Menus allows you to create powerful Terminal, Console and CMD environment menus. Any perl script used in a Terminal, Console or CMD environment can now include a menu facility that includes sub-menus, forward and backward navigation, single or multiple selection capabilities, dynamic item creation and customized banners. All this power is simple to implement with a straight forward and very intuitive configuration hash structure that mirrors the actual menu architecture needed by the application. A separate configuration file is optional. Term::Menus is cross platform compatible.

Test::LeakTrace provides several functions that trace memory leaks. This module scans arenas, the memory allocation system, so it can detect any leaked SVs in given blocks. Leaked SVs are SVs which are not released after the end of the scope they have been created. These SVs include global variables and internal caches. For example, if you call a method in a tracing block, perl might prepare a cache for the method. Thus, to trace true leaks, no_leaks_ok() and leaks_cmp_ok() executes a block more than once.

Term::Size::Perl is yet another implementation of Term::Size in pure Perl, with the exception of a C probe run on build time.

Test::CheckDeps adds a test that assures all dependencies have been installed properly. If requested, it can bail out all testing on error.

Test::Compile lets you check the validity of a Perl module file or Perl script file, and report its results in standard Test::Simple fashion.

This module provides a few subroutines for examining and modifying tied variables, including those that hold weak references to the objects to which they are tied (weak ties).

This module is used to check the portability across operating systems of the names of the files present in the distribution of a module.

Swarm is both a global distributed registry, like gproc, and a clustering utility. It was designed for the use case where large numbers of persistent processes are created for things like devices, and are unique across a cluster of Erlang nodes, and messages must be routed to those processes, both individually, and in groups. Additionally, Swarm is designed to distribute these processes evenly across the cluster based on a consistent hashing algorithm, and automatically move processes in response to cluster topology changes, or node crashes.

libqb is a library with the primary purpose of providing high performance client server reusable features. It provides high performance logging, tracing, ipc, and poll.
