Triceps is an innovative embeddable Complex Event Processing (CEP) system. It can be thought of as an in-memory database driven by triggers, or a data-flow machine working on a stream of events, or a spreadsheet on steroids. The major architectural advantages of Triceps include the direct use of procedural logic (as opposed to all-SQL systems), support of both compiled and general scripting languages (C++, Perl), light weight, and easy extensibility.
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.
