-The \TL{} installer supports only Cygwin 1.7.
 Before beginning the installation, use Cygwin's \filename{setup.exe} program to
 install the \filename{perl} and \filename{wget} packages if you have
 not already done so.  The following additional packages are
 recommended:
 \begin{itemize*}
-\item \filename{fontconfig} [needed by \XeTeX]
+\item \filename{fontconfig} [needed by \XeTeX\ and Lua\TeX]
 \item \filename{ghostscript} [needed by various utilities]
 \item \filename{libXaw7} [needed by \code{xdvi}]
 \item \filename{ncurses} [provides the \code{clear} command used by the installer]
