The package allows you to use the Ibycus 4 font for ancient
Greek with Babel. It uses a Perl script to generate hyphenation
patterns for Ibycus from those for the ordinary Babel encoding,
cbgreek. It sets up ibycus as a pseudo-language you can specify
in the normal Babel manner. For proper hyphenation of Greek
quoted in mid-paragraph, you should use it with elatex (all
current distributions of LaTeX are built with e-TeX, so the
constraint should not be onerous).
