Darius Tools is a collection of miscellaneous scripts which are useful for a variety of purposes. They are all designed to be faster and easier to use than the command line that would normally be required to accomplish the same task. For example, there are scripts for mass conversion of WAV files to Ogg files and Ogg files to WAV files, for converting LaTeX to PostScript and viewing the output in ggv, for creating image thumbnails, for converting from the Euro to another currency, for automated updating via FTP and for removing backups recursively. The Darius Tools are split among several packages according to different categories.
CL-BibTeX is a replacement for the BibTeX program, written in Common Lisp. The aim is to enable the user to format bibliographic entries using Common Lisp programs, rather than using the stack language of BibTeX style files. A compiler that transforms BibTeX style files into comprehensible Common Lisp programs is included.
gnome-courier is a collection of programs for courier services. It includes programs for managing clients, managing coworkers, managing jobs (receiving, distributing, and editing), printing bills and overdue notices, and managing the payroll. Various statistical modules are available, and since the project is based on a modular concept, it can easily be extended.
The Freehand Formula Entry System is a research prototype for recognizing online handwritten mathematical notation, developed jointly by researchers in New Zealand, the United States and Canada. A user draws expressions with a mouse or data tablet, and LaTeX, a bitmap, and an operator tree are produced as output. Symbol recognition and expression interpretation are performed as the user draws.
TeX++ is an implementation of (most parts of) TeX in C++, based on CommonTeX. It fits better into a Unix system by being able to act inside a pipe, has command line settings for page geometry and other typesetting parameters, and several other new features. It is intended as the typesetting engine for a TeX-based Web browser, but can be used standalone.
