# Tag Info

Questions with this tag are about the uses and problems with using the `soul` package for letterspacing, underlining, overstriking and highlighting, perhaps with the use of colour. Answers may show the use of `soul` but could also deal with limitations and alternative means to achieve the desired end.
`soul` is included in current versions of both TeX Live and MikTeX.
From the preamble to the `soul` documentation (e.g. on CTAN):
This article describes the soul package, which provides hyphenatable letterspacing (spacing out), underlining and some derivatives such as overstriking and highlighting. Although the package is optimized for LaTeX2ε , it also works with Plain TeX and with other flavors of TeX like, for instance, ConTeXt. By the way, the package name `soul` is only a combination of the two macro names `\so` (space out) and `\ul` (underline)---nothing poetic at all.
