Visual debugging for LuaTeX
===========================
The LuaTeX package `lua-visual-debug` shows boxes, glues, kerns and penalties in the PDF output.
Usage:
LaTeX:
\usepackage{lua-visual-debug}
or (plain)
\input lua-visual-debug.sty
Requirements: The package has only been tested with LuaTeX and
the formats plain and LaTeX. Other formats might work as well,
but other engines only show a warning message.
