Be prepared children: we’re heading for heavy church-geek waters.
The Rev. Chris Tessone (Even the Devils Believe) has typeset some public-domain chant settings using a TeX-derived application, OpusTeX. TeX (pronounced with a Greek chi) is a venerable typesetting system, still widely used through template packages and even graphic interfaces. In computing terms, there’s something foundational and powerful about TeX, like Latin itself, even though I put off exploring it more than a year ago as too esoteric for most producers of church-related documents. (Readers with advanced degrees in the hard sciences and mathematics may remember LaTeX with love or hate, as its use in creating theses and disserations is still robust and its ability to set mathematical formulae is unexcelled.)
I’ll be interested where Fr. Chris goes with this.
