+Just as with xparse, it is possible to use a special syntax consisting of
+single letters to express the arguments of a macro.  However, @code{lparse} is
+able to read arguments regardless of the macro systemd used -- whether LaTeX,
+or ConTeXt, or even plain TeX.  Of course, LuaTeX must always be used as the
+engine.")
