This package has been designed so to allow people to typeset Greek language documents using XeLaTeX. And it is released in the hope that people will use it and spot errors, bugs, features so to improve it. Practically, it provides all the capabilities of the greek option of the babel package. The package can be invoked with any of the following options: monotonic (for typesetting modern monotonic Greek), polytonic (for typesetting modern polytonic Greek), and ancient (for typesetting ancient texts). The default option is monotonic. The command \setlanguage{<lang>} to activate the hyphenation patterns of the language <lang> This, however, can be done only if the format file has not been built with the babel mechanism.
