Discussions about HieroTeX, an extension for the LaTeX text processor I made long time ago (1993 !), but which is very useful for long texts (e.g. books).
HieroTeX has been used for publishing a few books: Dagmar Budde, Die Göttin Seschat, and Vincent Pierre-Michel Laisney, L'enseignement d'Amenémopé.
As basically it works reasonably well, little work has been done on it since a few years, but at some point, I'll certainly write a Java engine for producing LaTeX code for hieroglyphs... except if someone feels like doing it right now :-)
