The CPAN shell (and module) automates or at least simplifies the building and installation of Perl modules and extensions. It includes some primitive searching capabilities and knows how to use Net::FTP, LWP, and certain external download clients to fetch distributions from the Internet. Then it automatically tests and installs them and their dependencies.
Module::Build is a system for building, testing, and installing Perl modules. It is meant to be an alternative to ExtUtils::MakeMaker. Developers may alter the behavior of the module through subclassing in a much more straightforward way than with EU::MM. It also does not require a 'make' on your system: most of the Module::Build code is pure Perl and written in a very cross-platform way. In fact, you don't even need a shell, so even platforms like Mac OS (traditional) can use it fairly easily.
Pod::Manual is a module that gathers the pod of several Perl modules into a comprehensive manual. Its primary objective is to generate a document that can be printed, but it also allow to output the document into other formats (e.g., docbook). podmanual is a utility that uses Pod::Manual.
Hook::LexWrap allows you to install a pre- or post-wrapper (or both) around an existing subroutine. Unlike other modules that provide this capacity (e.g. Hook::PreAndPost and Hook::WrapSub), Hook::LexWrap implements wrappers in such a way that the standard 'caller' function works correctly within the wrapped subroutine.
Net::SMPP is a Perl module that implements versions 3.4, 4.0, and 5.0 of the SMPP protocol for ESME and SMSC roles. SMPP is commonly used by clients and servers for sending SMS messages in mobile network. This module allows you to implement an SMS client, an SMS server, or even an SMS proxy. It supports all standard TLVs and some vendor specific TLVs as well.
Cruddy! is an instant CRUD Web front-end, featuring auto-discovery of the data dictionary. It is similar to phpMyAdmin in the plug-and-play manner, but much more user-friendly for staff and clients with access restrictions. Unlike phpMyAdmin, Cruddy!'s underlying CGI::CRUD is a full object-oriented webapp development framework. Currently, Oracle and MySQL RDBMS are supported. Cruddy! is stable and used in several production sites around the world including ValueClick, Inc.
