texlive-generic-ulem 51265 Underline text in TeX
The package provides an
\ul (underline) command which will break over line ends; this technique may be used to replace
\em (both in that form and as the
\emph command), so as to make output look as if it comes from a typewriter. The package also offers double and wavy underlining, and striking out (line through words) and crossing out (/// over words).
