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

This package provides a simple Perl library to extract height/width from images.

Exception::Class allows you to declare exception hierarchies in your modules in a "Java-esque" manner.

List::Compare provides a module to perform comparative operations on two or more lists. Provided operations include intersections, unions, unique elements, complements and many more.

Class::XSAccessor implements fast read, write, and read/write accessors in XS. Additionally, it can provide predicates such as "has_foo()" for testing whether the attribute "foo" is defined in the object. It only works with objects that are implemented as ordinary hashes. Class::XSAccessor::Array implements the same interface for objects that use arrays for their internal representation.

This module provides a clone() method which makes recursive copies of nested hash, array, scalar and reference types, including tied variables and objects.

The namespace::clean pragma will remove all previously declared or imported symbols at the end of the current package's compile cycle. Functions called in the package itself will still be bound by their name, but they won't show up as methods on your class or instances.

Socket::MsgHdr provides advanced socket messaging operations via sendmsg and recvmsg.

It also allows manipulating ancillary data or so-called control information (cmsghdr). This ancillary data may be used for file descriptor passing, IPv6 operations, and a host of implementation-specific extensions.

This module is used by Schmorp's modules during configuration stage to test the installed perl for compatibility with his modules.

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.

MIME::Charset provides information about character sets used for MIME messages on Internet.

This toolkit primarily provides modules for performing both traditional and object-oriented i/o) on things *other* than normal filehandles; in particular, IO::Scalar, IO::ScalarArray, and IO::Lines.

File::Find::Object::Rule is an alternative Perl interface to File::Find::Object.

The functions exported by this module deal with runtime handling of Perl modules, which are normally handled at compile time.

The Getopt::Long module implements an extended getopt function called GetOptions(). It parses the command line from ARGV, recognizing and removing specified options and their possible values.

This function adheres to the POSIX syntax for command line options, with GNU extensions. In general, this means that options have long names instead of single letters, and are introduced with a double dash "--". Support for bundling of command line options, as was the case with the more traditional single-letter approach, is provided but not enabled by default.

This package provides some basic statistics on numerical vectors. All the subroutines can take a reference to the vector to be operated on.

Module::Build::XSUtil is subclass of Module::Build for support building XS modules.

This is a list of a new parameters in the Module::Build::new method:

1. needs_compiler_c99: This option checks C99 compiler availability.

2. needs_compiler_cpp: This option checks C++ compiler availability. Can also pass extra_compiler_flags and extra_linker_flags for C++.

3. generate_ppport_h: Generate ppport.h by Devel::PPPort.

4. generate_xshelper_h: Generate xshelper.h which is a helper header file to include EXTERN.h, perl.h, XSUB.h and ppport.h, and defines some portability stuff which are not supported by ppport.h.

   It is ported from Module::Install::XSUtil.

5. cc_warnings: Toggle compiler warnings. Enabled by default.

6. -g options: Invoke Build.PL with -g to enable debug options.

Guard implements so-called guards. A guard is something (usually an object) that "guards" a resource, ensuring that it is cleaned up when expected.

Specifically, this module supports two different types of guards: guard objects, which execute a given code block when destroyed, and scoped guards, which are tied to the scope exit.

Dates are complex enough without times and timezones. This module may be used to create simple date objects. It handles validation, interval arithmetic, and day-of-week calculation. It does not deal with hours, minutes, seconds, and time zones.

This module tries to make it easy to build Perl extensions that use functions and typemaps provided by other perl extensions. This means that a perl extension is treated like a shared library that provides also a C and an XS interface besides the perl one.

MooseX::Types::LoadableClass provides a ClassName type constraint with coercion to load the class.

This module converts Perl data structures to JSON and vice versa.

This subclass of Module::Build adds some tools and processes to make it easier to use for wrapping C++ using XS++ (ExtUtils::XSpp).

Text::Diff provides a basic set of services akin to the GNU diff utility. It is not anywhere near as feature complete as GNU diff, but it is better integrated with Perl and available on all platforms. It is often faster than shelling out to a system's diff executable for small files, and generally slower on larger files.
