File::Next is a Perl CPAN module for finding files.

MooseX::NonMoose allows for easily subclassing non-Moose classes with Moose, taking care of the details connected with doing this, such as setting up proper inheritance from Moose::Object and installing (and inlining, at make_immutable time) a constructor that makes sure things like BUILD methods are called. It tries to be as non-intrusive as possible.

This package provides a Perl library to read multiple hunks of data out of your DATA section.

Log::Any::Adapter::Log4perl provides a Log::Any adapter using Log::Log4perl for logging.

This module implements an interface to the Linux 2.6.13 and later Inotify file change notification system.

This module provides convenience methods that let you easily create DateTime::Set objects for RFC 2445 style recurrences.

Sys::Hostname::Long tries very hard to get the full hostname of a system.

Loading MooX::StrictConstructor makes your constructors "strict". If your constructor is called with an attribute init argument that your class does not declare, then it dies.

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.

This package provides procedures to create read-only scalars, arrays, and hashes.

"require EXPR" only accepts Class/Name.pm style module names, not Class::Name. For that, this module provides "load_class 'Class::Name'".

This module understands the formats used by SQLite for its date, datetime and time functions. It can be used to parse these formats in order to create DateTime objects, and it can take a DateTime object and produce a timestring accepted by SQLite.

Contains the MooX and MooX::Role packages.

Crypt::DES is an XS-based implementation of the DES cryptography algorithm. The module implements the Crypt::CBC interface which has blocksize, keysize, encrypt and decrypt functions.

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.

Exporter::Lite is an alternative to Exporter, intended to provide a lightweight subset of the most commonly-used functionality. It supports import(), @EXPORT and @EXPORT_OK and not a whole lot else.

This Perl module implements Perl hashes that preserve the order in which the hash elements were added. The order is not affected when values corresponding to existing keys in the IxHash are changed. The elements can also be set to any arbitrary supplied order. The familiar perl array operations can also be performed on the IxHash.

Devel::GlobalDestruction provides a function returning the equivalent of "${^GLOBAL_PHASE} eq 'DESTRUCT'" for older perls.

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.

Role::Tiny is a minimalist role composition tool.

This package transparently speeds up functions by caching return values, trading space for time.

List::MoreUtils::XS provides some trivial but commonly needed functionality on lists which is not going to go into List::Util.

You use Tie::Cycle to go through a list over and over again. Once you get to the end of the list, you go back to the beginning.

MailTools contains the following modules:

Mail::Address

Parse email address from a header line.

Mail::Cap

Interpret mailcap files: mappings of file-types to applications as used by many command-line email programs.

Mail::Field

Simplifies access to (some) email header fields. Used by Mail::Header.

Mail::Filter

Process Mail::Internet messages.

Mail::Header

Collection of Mail::Field objects, representing the header of a Mail::Internet object.

Mail::Internet

Represents a single email message, with header and body.

Mail::Mailer

Send Mail::Internet emails via direct smtp or local MTA's.

Mail::Send

Build a Mail::Internet object, and then send it out using Mail::Mailer.

Mail::Util

"Smart functions" you should not depend on.
