The libwww-perl collection is a set of Perl modules which provides a
simple and consistent application programming interface to the World-Wide
Web. The main focus of the library is to provide classes and functions
that allow you to write WWW clients. The library also contain modules that
are of more general use and even classes that help you implement simple
HTTP servers.

perl-libxml-perl is a collection of Perl modules for working with XML.

This module provides a simple object for logging to files under the
Log::Dispatch::* system, and automatically rotating them according to
different constraints. This is basically a Log::Dispatch::File wrapper
with additions. To that end the arguments

name, min_level, filename and mode

behave the same as Log::Dispatch::File. So see its man page (perldoc
Log::Dispatch::File)

Mail::Mbox::MessageParser is a feature-poor but very fast mbox parser.
It uses the best of three strategies for parsing a mailbox: either
using cached folder information, GNU grep, or highly optimized Perl.

The Mcrypt module provides a simple and intuitive Perl abstraction of
the libmcrypt cryptography library. It provides mechanisms for
encoding and decoding Perl scalars.

MIME::Lite is intended as a simple, standalone module for generating
(not parsing!) MIME messages... specifically, it allows you to output a
simple, decent single- or multi-part message with text or binary
attachments. It does not require that you have the Mail:: or MIME::
modules installed.

modules for parsing (and creating!) MIME entities

MIME types are used in MIME entities, for instance as part of e-mail
and HTTP traffic. Sometimes real knowledge about a mime-type is need.
This module will supply it.

MLDBM, the Perl module that can be used to store multidimensional hash
structures in tied hashes (including DBM files).

This module wraps around the MLDBM interface, by handling concurrent
access to MLDBM databases with file locking, and flushes i/o explicity
per lock/unlock. The new [Read]Lock()/UnLock() API can be used to
serialize requests logically and improve performance for bundled reads
& writes.

Net::DNS is a Perl interface to the DNS resolver. It allows the
programmer to perform any type of DNS query from a Perl script. For
details and examples, please read the Net::DNS manual page.

You can either use the simple interface, which does one ident lookup at a
time, or use the asynchronous interface to perform (possibly) many
simultaneous lookups, or simply continue serving other things while the
lookup is proceeding.

This is the Net::IP module, designed to allow easy manipulation of IPv4
and IPv6 addresses.

Net::Jabber is a convenient tool to use for any perl script that would
like to utilize the Jabber Instant Messaging protocol. While not a
client in and of itself, it provides all of the necessary back-end
functions to make a CGI client or command-line perl client feasible and
easy to use. Net::Jabber is a wrapper around the rest of the official
Net::Jabber::xxxxxx packages.

Parse, manipulate and lookup IP network blocks.

Net::Server is an extensible, generic Perl server engine. Net::Server
combines the good properties from Net::Daemon (0.34), NetServer::Generic
(1.03), and Net::FTPServer (1.0), and also from various concepts in the
Apache Webserver.

The Net::SNMP module abstracts the intricate details of the Simple
Network Management Protocol by providing a high level programming
interface to the protocol. Each Net::SNMP object provides a one-to-one
mapping between a Perl object and a remote SNMP agent or manager. Once an
object is created, it can be used to perform the basic protocol exchange
actions defined by SNMP.

There is a related module called Net::SSLeay::Handle included in this
distribution that you might want to use instead. It has its own pod
documentation.

Net::Telnet allows you to make client connections to a TCP port and do
network I/O, especially to a port using the TELNET protocol. Simple
I/O methods such as print, get, and getline are provided. More
sophisticated interactive features are provided because connecting to a
TELNET port ultimately means communicating with a program designed for
human interaction. These interactive features include the ability to
specify a time-out and to wait for patterns to appear in the input
stream, such as the prompt from a shell.

Net::XMPP is a convenient tool to use for any perl script that would
like to utilize the XMPP Instant Messaging protocol. While not a
client in and of itself, it provides all of the necessary back-end
functions to make a CGI client or command-line perl client feasible and
easy to use. Net::XMPP is a wrapper around the rest of the official
Net::XMPP::xxxxxx packages.

This module provides an interface to the protocol family represented by
IMAP, IMSP, ACAP, and ICAP. A usable IMAP module is also provide.

This module lets you quickly and easily construct new packages.
It gives them unused names and sets up their package data,
if provided.

The Params::Validate module allows you to validate method or function
call parameters to an arbitrary level of specificity. At the simplest
level, it is capable of validating the required parameters were given
and that no unspecified additional parameters were passed in.

It is also capable of determining that a parameter is of a specific
type, that it is an object of a certain class hierarchy, that it
possesses certain methods, or applying validation callbacks to
arguments.

The Comprehensive Perl Archive Network (CPAN) is a very useful collection
of Perl code. It has several indices of the files that it hosts, including
a file named "02packages.details.txt.gz" in the "modules" directory. This
file contains lots of useful information and this module provides a simple
interface to the data contained within.
