This may be working as-is for greek and bilingual (greek & english)
text, but it's actually work in progress.  I'll come back to it.

We have an issue with fonts, try to figure out how to make this
parametric.  We also have an issue with appendix numbers in Greek
(that's why I have "numerals=arabic" for greek).

This is the first version that plays with xelatex and utf8.

The old versions used to work with "grlatex", which will most
probably be impossible to find.  I don't think you have a fat
chance of working with these sources.  Wait until the later
versions, based on xelatex.

Hardwired in many places, bad implementation.
Just before the diploma project of Kyriakos Ginis.

which included commits to RCS files with non-trunk default branches.
