This module has 3 functions: one to copy files only, one to copy directories only, and one to do either depending on the argument's type.

Exporter implements an import method which allows a module to export functions and variables to its users' namespaces. Many modules use Exporter rather than implementing their own import method because Exporter provides a highly flexible interface, with an implementation optimised for the common case.

The Specio distribution provides classes for representing type constraints and coercion, along with syntax sugar for declaring them. Note that this is not a proper type system for Perl. Nothing in this distribution will magically make the Perl interpreter start checking a value's type on assignment to a variable. In fact, there's no built-in way to apply a type to a variable at all. Instead, you can explicitly check a value against a type, and optionally coerce values to that type.

This module exports a single function: ttie. It ties a variable to a type constraint, ensuring that whatever values stored in the variable will conform to the type constraint. If the type constraint has coercions, these will be used if necessary to ensure values assigned to the variable conform.

This package eases the writing of command line utilities, accepting commands and subcommands and so on. These commands can form a tree, which is mirrored in the package structure. On invocation, each command along the path through the tree (starting from the top-level command through to the most specific one) is instantiated.

This module provides a flexible calling interface to some frequently-performed string conversion functions, including applying and expanding standard C/Unix-style backslash escapes like and , wrapping and removing double-quotes, and truncating to fit within a desired length.

The File::LibMagic module is a simple perl interface to libmagic from the file package.

Parse::RecDescent can incrementally generate top-down recursive-descent text parsers from simple yacc-like grammar specifications.

This module allows you to execute code when perl finished compiling the surrounding scope.

This module provides convenience methods that let you easily create DateTime::Set objects for various recurrences, such as "once a month" or "every day". You can also create more complicated recurrences, such as "every Monday, Wednesday and Thursday at 10:00 AM and 2:00 PM".

MIME-tools is a collection of Perl5 MIME:: modules for parsing, decoding, and generating single- or multipart (even nested multipart) MIME messages.

Text::CSV_XS provides facilities for the composition and decomposition of comma-separated values. An instance of the Text::CSV_XS class will combine fields into a CSV string and parse a CSV string into fields. The module accepts either strings or files as input and support the use of user-specified characters for delimiters, separators, and escapes.

Sys::SigAction is a Perl extension for Consistent Signal Handling.

AppConfig is a bundle of Perl5 modules for reading configuration files and parsing command line arguments.

This module allows you to call isa, can, does, and DOES safely on things that may not be objects.

This module provides a list of known mime-types, combined from various sources. For instance, it contains all IANA types and the knowledge of Apache.

Pod::Simple is a Perl library for parsing text in the Pod (plain old documentation) markup language that is typically used for writing documentation for Perl and for Perl modules.

When searching through large amounts of data, it is often the case that a result set is returned that is larger than we want to display on one page. This results in wanting to page through various pages of data. The maths behind this is unfortunately fiddly, hence this module.

Log::Any provides a standard log production API for modules. Log::Any::Adapter allows applications to choose the mechanism for log consumption, whether screen, file or another logging mechanism like Log::Dispatch or Log::Log4perl.

A CPAN module uses Log::Any to get a log producer object. An application, in turn, may choose one or more logging mechanisms via Log::Any::Adapter, or none at all.

Log::Any has a very tiny footprint and no dependencies beyond Perl itself, which makes it appropriate for even small CPAN modules to use. It defaults to null logging activity, so a module can safely log without worrying about whether the application has chosen (or will ever choose) a logging mechanism.

Text::Table renders plaintext tables.

This module provides various type-testing functions. These are intended for functions that care what type of data they are operating on. There are two flavours of function. Functions of the first flavour provide type classification only. Functions of the second flavour also check that an argument is of an expected type. The type enforcement functions handle only the simplest requirements for arguments of the types handled by the classification functions. Enforcement of more complex types may be built using the classification functions, or it may be more convenient to use a module designed for the more complex job, such as Params::Validate

This Perl module provides Unicode normalization forms.

Module::Refresh provides ways to refresh %INC files when updated on disk.

DateTime is a class for the representation of date/time combinations. It represents the Gregorian calendar, extended backwards in time before its creation (in 1582).
