GNU libmatheval is a library which contains several procedures that make it possible to create an in-memory tree from the string representation of a mathematical function over single or multiple variables. This tree can be used later to evaluate a function for specified variable values, to create a corresponding tree for the function derivative over a specified variable or to write a textual tree representation to a specified string. The library exposes C and Fortran 77 interfaces.

CVSps is a program for generating 'patchset' information from a CVS repository. A patchset in this case is defined as a set of changes made to a collection of files, and all committed at the same time (using a single 'cvs commit' command). This information is valuable to seeing the big picture of the evolution of a cvs project. While cvs tracks revision information, it is often difficult to see what changes were committed 'atomically' to the repository.

PatchReader is a set of utilities for reading in, transforming, and doing various other things with a patch. It basically allows you to create a chain of readers that can read a patch, remove files from a patch, add CVS context, fix up the patch root according to CVS, and output the patch as raw unified or through a template processor (used in some places to output a patch as HTML).

** If you are unfamiliar with testing read Test::Tutorial first! ** This is a simple, basic module for checking whether a class is a Singleton. A Singleton describes an object class that can have only one instance in any system. An example of a Singleton might be a print spooler or system registry, or any kind of central dispatcher. For a description and discussion of the Singleton class, see "Design Patterns", Gamma et al, Addison-Wesley, 1995, ISBN 0-201-63361-2.

vcp is a tool for copying revision controlled files between various SCM repositories. For example, using vcp, it is possible to copy the contents of a entire Perforce depot (or part of one) into a depot on a different Perforce server or to copy the contents of a CVS repository into a Perforce server (or vice-versa). This port is a private snapshot because p5-VCP's distribution files is gone from the MASTER_SITE, and does not currently work with svk.

UAE is a mostly complete software emulation of the hardware of the Commodore Amiga 500/1000/2000. Commodore Amiga, for those who don't know, is a 16/32 bit computer system based on the Motorola 680x0 CPU and a few specially designed custom chips that provide very good graphics and sound capabilities. Its first incarnation, the A1000, appeared in 1985, followed by the highly successful A500 and A2000 models. Requires a valid Amiga ROM file in order to be useful.

This are Text utilities for use with the GD drawing package. This package provides three modules: GD::Text: Provides information about a font, irrespective of whether the font is a TTF or builtin font. GD::Text::Align Align a string around a coordinate, left, right, center, top, bottom or center. GD::Text::Wrap Wrap a long string between a right and left margin, starting at a certain y coordinate. Layout the text flush left, flush right, center, or justified.

DejaGnu is a framework for testing other programs. Its purpose is to provide a single front end for all tests. Think of it as a custom library of Tcl procedures crafted to support writing a test harness. A Test Harness is the testing infrastructure that is created to support a specific program or tool. Each program can have multiple testsuites, all supported by a single test harness. DejaGnu is written in Expect, which in turn uses Tcl -- Tool command language.

The FreeRADIUS Client is a framework and library for writing RADIUS Clients which additionally includes radlogin, a flexible RADIUS aware login replacement, a command line program to send RADIUS authentication/authorisation requests and accounting records and a utility to query the status of a RADIUS server. All these programs are based on a library which lets you develop a RADIUS-aware application in less than 50 lines of C code. It is highly portable and runs on Linux, many BSD variants and Solaris.
