ASAPlate separates PHP source code from templates. The library is based on FastTemplate, but the project has a different philosophy. It is easy to learn and use. There's no need to especify in the source code which templates will be found in the template files. Template files can be edited with any WYSIWYG editor, can be dynamic, and are recursively parsed.
MP3-CD-Sleeve is composed of two Perl scripts that produce HTML or LaTeX-style pages that can be printed as the index sleeve of an (MP3) CD. It briefly lists the directory hierarchy, by enumerating directories for ease of use in MP3 CD players. The LaTeX script tries to fit everything in a 5" x 5" (12.5cm x 12.5 cm) frame with wrap-around at the edges (no fold-out feature is included yet, it produces just the front cover).
XMLPublication is a set of tools to generate Web pages from (possibly large) desktop documents or other structured documents, such as books with paragraphs, or tabular data. It cuts documents into Web pages, and creates customizable multi-indices. All this is done through a repeatable process in which data is separated from presentation and user settings. It uses XML techniques, particularly XSLT and Ant.
