RTK (Ruckus Tool Kit) is a high-performance, Perl-based, dynamic, content-generation system. It provides a nearly transparent bridge between HTML-based code pages and traditional CGI-based systems. It has been designed to automatically take advantage of existing systems, such as basic CGI, Apache's mod_perl, FastCGI, and SpeedyCGI, but does not require such systems for high-performance optimization.
Monotone::AutomateStdio is a Perl library module for accessing Monotone's automate stdio interface. Monotone is a distributed, change-set based SCM system. It has a mode where commands can be sent to it via STDIN and output read from it via STDOUT. Monontone::AutomateStdio makes use of this facility to provide the Perl programmer with a programmatic interface to Monotone.
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.
CGI::ContactForm is a Perl module that generates a contact form for the Web and sends a message to a predestinated recipient. Unlike many form-to-mail programs, it's limited to this single purpose, but it allows you to set up a decently designed form with a minimum of effort. In other words, it's simple to use rather than flexible, even if there are quite a few customization possibilities.
