pdfTeX is an extended version of TeX that can create PDF directly from TeX source files and enhance the result of TeX typesetting with the help of PDF. When PDF output is not selected, pdfTeX produces normal DVI output, otherwise it produces PDF output that looks identical to the DVI output. An important aspect of this project is to investigate alternative justification algorithms, optionally making use of multiple master fonts.
ChordDB is a Web-based database front-end for keeping track of and typesetting chord files (a.k.a. guitar fake sheets). It accepts chord and chordpro files as inputs, and creates output sets in a large variety of formats (PDF, text, chordpro, LaTeX) with the help of pdftex and the LaTeX Songbook style. Songs are stored internally using SQLite, so there is very little need for configuration.
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).
