Looking up module information / loading at runtime
Module::Load::Conditional provides simple ways to query and possibly load any of the modules you have installed on your system during runtime. It is able to load multiple modules at once or none at all if one of them was not able to load. It also takes care of any error checking and so forth.

Tools for working with directory and file names.
The Carp routines are useful in your own modules because they act like die() or warn(), but with a message which is more likely to be useful to a user of your module. In the case of cluck, confess, and longmess that context is a summary of every call in the call-stack. For a shorter message you can use carp or croak which report the error as being from where your module was called. There is no guarantee that that is where the error was, but it is a good educated guess.
High resolution time, sleep, and alarm for perl
Implement usleep, ualarm, and gettimeofday for Perl, as well as wrappers to implement time, sleep, and alarm that know about non-integral seconds.
This pragma allows you to declare constants at compile-time. When a constant is used in an expression, Perl replaces it with its value at compile time, and may then optimize the expression further. In particular, any code in an "if (CONSTANT)" block will be optimized away if the constant is false.
Networking constants and support functions
This module provides a variety of constants, structure manipulators and other functions related to socket-based networking. The values and functions provided are useful when used in conjunction with Perl core functions such as socket(), setsockopt() and bind(). It also provides several other support functions, mostly for dealing with conversions of network addresses between human-readable and native binary forms, and for hostname resolver operations.
Finding and running system commands made easy
IPC::Cmd allows for the searching and execution of any binary on your system. It adheres to verbosity settings and is able to run intereactive. It also has an option to capture output/error buffers.
A highly capable, feature-rich programming language
Perl 5 is a highly capable, feature-rich programming language with over 30 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large scale development projects.
This utility is designed to write a Makefile for an extension module from a Makefile.PL. It is based on the Makefile.SH model provided by Andy Dougherty and the perl5-porters. It splits the task of generating the Makefile into several subroutines that can be individually overridden. Each subroutine returns the text it wishes to have written to the Makefile. As there are various Make programs with incompatible syntax, which use operating system shells, again with incompatible syntax, it is important for users of this module to know which flavour of Make a Makefile has been written for so they'll use the correct one and won't have to face the possibly bewildering errors resulting from using the wrong one. On POSIX systems, that program will likely be GNU Make; on Microsoft Windows, it will be either Microsoft NMake, DMake or GNU Make. See the section on the "MAKE" parameter for details. ExtUtils::MakeMaker (EUMM) is object oriented. Each directory below the current directory that contains a Makefile.PL is treated as a separate object. This makes it possible to write an unlimited number of Makefiles with a single invocation of WriteMakefile(). All inputs to WriteMakefile are Unicode characters, not just octets. EUMM seeks to handle all of these correctly. It is currently still not possible to portably use Unicode characters in module names, because this requires Perl to handle Unicode filenames, which is not yet the case on Windows.
Parse text into an array of tokens or array of arrays
The &nested_quotewords() and &quotewords() functions accept a delimiter (which can be a regular expression) and a list of lines and then breaks those lines up into a list of words ignoring delimiters that appear inside quotes. &quotewords() returns all of the tokens in a single long list, while &nested_quotewords() returns a list of token lists corresponding to the elements of @lines. &parse_line() does tokenizing on a single string. The &*quotewords() functions simply call &parse_line(), so if you're only splitting one line you can call &parse_line() directly and save a function call. The $keep argument is a boolean flag. If true, then the tokens are split on the specified delimiter, but all other characters (including quotes and backslashes) are kept in the tokens. If $keep is false then the &*quotewords() functions remove all quotes and backslashes that are not themselves backslash-escaped or inside of single quotes (i.e., &quotewords() tries to interpret these characters just like the Bourne shell). NB: these semantics are significantly different from the original version of this module shipped with Perl 5.000 through 5.004. As an additional feature, $keep may be the keyword "delimiters" which causes the functions to preserve the delimiters in each string as tokens in the token lists, in addition to preserving quote and backslash characters.
This package is the shared library for perl.
Implements default import method for modules
The Exporter module implements an import method which allows a module to export functions and variables to its users' name spaces. Many modules use Exporter rather than implementing their own import method because Exporter provides a highly flexible interface, with an implementation optimized for the common case.
Generic input parsing/checking mechanism
Params::Check Allows for generic input checking and validating using a powerfull templating system, providing default values and so on.
