This package has been designed so to allow people to typeset Greek language documents using XeLaTeX or LuaLaTeX. 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.
