The Coral Tree Library Set includes modules for basic operating system abstractions, general purpose templates and classes, well behaved application modules, platform independent builder, thread abstraction, network abstractions, event/window system abstraction, and a widget set for the event/window system abstraction.

Doxygen is a cross-platform, JavaDoc-like documentation system for C++, C, Objective-C, C#, Java, IDL, Python, PHP, VHDL, and Fortran. Doxygen can be used to generate an on-line class browser (in HTML) and/or an off-line reference manual (in LaTeX or RTF) from a set of source files. Doxygen can also be configured to extract the code-structure from undocumented source files. This includes dependency graphs, class diagrams and hyperlinked source code. This type of information can be very useful to quickly find your way in large source distributions.
mkrdns is a small Perl script that helps automate changes to your DNS zone files. It does this by reading your named.boot/named.conf file to find all the domains/networks for which you are authoritative. It then reads all of the forward zone files and generates PTR records which it inserts in the reverse zone maps.
Lout is a document formatting system which reads a high-level description of a document similar in style to LaTeX and produces a PostScript file which can be printed on most laser printers and graphic display devices. Plain text and PDF output are also available. Lout is inherently multilingual and adding new languages is easy.
GNU libavl is a library in ANSI/ISO C for the manipulation of binary trees and balanced binary trees. It is written using a literate programming system called TexiWEB. By way of TexiWEB, libavl is as much a textbook on binary trees and balanced binary trees as it is a collection of code.
