Class::EHierarchy is intended for use as a base class for custom objects. The objects need one or more of the following features: orderly bottom-up destruction of objects, opaque objects, class-based access restrictions for properties and methods, primitive strict property type awareness, and alias-based object retrieval.
The Paranoid modules provide a number of routines that are intended for use in strict and taint-safe scripts. The modules cover a variety of tasks from command-line argument parsing to process and network management. All of the modules use a debug trace framework for diagnostic output that is easily used and extended for application code as well.
The metric implemented in the Image::Density Perl Module estimates the density of data where there is data, and has a reasonable correlation with goodness as judged by humans. That is, if you let a human look at a set of images and judge quality, the density values for those images as calculated here tend to correlate well with the human judgement (densities that are too high or too low represent "bad'' images). It is intended for use on bitonal TIFF images, such as those from scanning paper documents.
Inq is a scripting language for client/server systems. The server provides transaction, persistence, concurrency, and events support. The client is presently desktop only, though Web clients are planned. Inq uses a generic node structure throughout and reification techniques to obviate boilerplate code, especially in the areas of persistence and MVC.
Radiance is a set of tools which provide an advanced lighting simulation software package. It allows very detailed definition of materials' and light sources' properties through the use of advanced techniques like brdf and ies files, as well as a powerful mathematical scripting language, resulting in accurate renderings of scenes which are usually imported from CAD and 3D modelers. It uses the hybrid approach of Monte Carlo and deterministic ray tracing to achieve a reasonably accurate result in a reasonable time.
jIRCii is a cross platform Internet Relay Chat client. It is fully scriptable using a Perl-like language called sleep. The focus is to provide a console client experience with the advantages of a solid GUI. It includes DCC/CTCP support, the ability to connect to SSL servers, and over 65 built-in commands.
