Underlining Package for LaTeX

If you want to use underlining (standard or wavy) or strikethroughs in LaTeX, consider adding

\usepackage[normalem]{ulem}

to your LaTeX source file. This opens up the following useful commands:

Command	Description
\uline{foo}	Underlines foo
\uuline{foo}	Double underlines foo
\uwave{foo}	Underlines foo with a wavy line
\sout{foo}	Strikesout foo
\xout{foo}	Crosses out foo with `/'

And don't forget that you can use \emph{foo} to obtain an italicised version of foo.

These are preferable over \underline{foo} and {\em foo} because they can handle the edge cases of spanning multiple lines (for underlining) and the space correction after italicisation (for the emphasis component).
