+and configurable variant of TeX while at the same time offering downward
+compatibility.  LuaTeX uses Unicode (as UTF-8) as its default input encoding,
+and is able to use modern (OpenType) fonts (for both text and mathematics).
+It should be noted that LuaTeX is still under development; its specification
+has been declared stable, but absolute stability may not in practice be
+assumed.")
