This package implements usleep, ualarm, and gettimeofday for Perl, as well as wrappers to implement time, sleep, and alarm that know about non-integral seconds.

Internationalized Domain Names (IDNs) use characters drawn from a large repertoire (Unicode), but IDNA allows the non-ASCII characters to be represented using only the ASCII characters already allowed in so-called host names today (letter-digit-hyphen, /[A-Z0-9-]/i).

Use this module if you just want to convert domain names (or email addresses), using whatever IDNA standard is the best choice at the moment.

Term::ProgressBar is a wonderful module for showing progress bars on the terminal. This module acts very much like that module when it is run interactively. However, when it is not run interactively (for example, as a cron job) then it does not show the progress bar.

XML::Writer is a simple Perl module for writing XML documents: it takes care of constructing markup and escaping data correctly. By default, it also performs a significant amount of well-formedness checking on the output to make certain (for example) that start and end tags match, that there is exactly one document element, and that there are not duplicate attribute names.

This package provides a way to memory map a file.

Crypt::MySQL emulates the MySQL PASSWORD() function. The module does not depend on an interface to the MySQL database server. This enables the comparison of encrypted passwords without the need for a real MySQL environment.

This module handles parsing, modifying and creating configuration files of the style used by the Git version control system.

This module implements a subset of the YAML specification for use in reading and writing CPAN metadata files like META.yml and MYMETA.yml.

IO::Pager can be used to locate an available pager and use it to display output if a TTY is in use.

This package is a companion module to DateTime.pm. It implements the Julian calendar. It supports everything that DateTime.pm supports and more: about one day per century more, to be precise.

This module facilitates using Moose or Mouse modules without changing the code. By default, Mouse will be provided to libraries, unless Moose is already loaded, or explicitly requested by the end-user. End users can force the decision of which backend to use by setting the environment variable ANY_MOOSE to be Moose or Mouse.

This package provides encodings for JIS X 0212, which is also known as JIS 2000.

Data::UUID provides a framework for generating Universally Unique Identifiers (UUIDs), also known as Globally Unique Identifiers (GUIDs). A UUID is 128 bits long, and is guaranteed to be different from all other UUIDs/GUIDs generated until 3400 CE.

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.

The Time::Warp module offers developers control over the measurement of time.

The Devel::StackTrace module contains two classes, Devel::StackTrace and Devel::StackTrace::Frame. These objects encapsulate the information that can be retrieved via Perl's caller() function, as well as providing a simple interface to this data.

Locale::gettext provides an object oriented interface to the internationalization functions provided by the C library.

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.

This module exports a single hash (%RE) that stores or generates commonly needed regular expressions. Patterns currently provided include: balanced parentheses and brackets, delimited text (with escapes), integers and floating-point numbers in any base (up to 36), comments in 44 languages, offensive language, lists of any pattern, IPv4 addresses, URIs, and Zip codes.

This module provide a convenient way to create directories of arbitrary depth and to delete an entire directory subtree from the file system.

This module is a data dumper optimized for logging of arbitrary parameters.

File::Find::Rule is a friendlier interface to File::Find. It allows you to build rules which specify the desired files and directories.

This module allows code attributes of methods to be introspected using Moose meta method objects.

Routines to manipulate defhash, a convention to define things more precisely and uniformly using a hash, in Perl.
