\begin{document}
This short paragraph demonstrates the usefulness
of the packages \textsf{showhyphenation} and
\textsf{check-lua-hyphens}. The first
automatically marks all hyphenation points found
by the engine with a small triangular mark. The
second package writes out all hyphenations that
happened in the document into a file with the
extension \texttt{.uhy}. You can then examine
that file to find any issues with the
hyphenation and correct them as necessary.
