If you use LaTeX, and want to typeset hieroglyphic texts, this package is for you. If you want to typeset hieroglyphs, and don't know LaTeX, then have a look at the file EGypto.tex, to get an idea of what LaTeX looks like.
You can use also use the (ugly, but getting better) fonts for your own programs. There are both a metafont and gsf (postscript type I) fonts. The fonts were made with the GNU fontutils.
