Texpipeline allows the conversion of (La)TeX documents with simple filter pipes such as "cat input.tex | tex2pdf > output.pdf". It removes the hassle of running (la)tex again and again, leaving lots of auxiliary files in the current directory. This is especially useful for programs which create LaTeX files automatically and just want to present the PDF output to the user.
RefDB is a reference database and bibliography tool for SGML, XML, and LaTeX documents. Command-line tools allow interactive or scriptable access to the data which are stored in a SQL database. RefDB can also be accessed through a Web interface, a SRU interface, or via editor extensions (Emacs/vim). Libraries for Perl and PHP are available for programmers. RefDB provides sophisticated character encoding handling, using Unicode by default.
dvdmenuauthor makes it easy and efficient to author a DVD with menus in an indirect (non-WYSIWYG) way. An XML project file drives the DVD authoring, from which both menus and a dvdauthor XML file are generated. dvdauthor and spumux are then used to author the DVD filesystem. Menu items (buttons and static items such as images and text) can be specified conscisely in the project XML file with LaTeX markup (to be processed by pdfLaTeX and rendered by xpdf).
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.
