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.
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).
