The soul package
Melchior Franz · 2002
This article describes the soul package 1 , which provides h y p h e n a t a b l e l e t t e r s p a c i n g ( s p a c i n g o u t ) , underlining and some derivatives such as overstriking and highlighting. Although the package is optimized for L ATEX 2, it also works with Plain TEX and with other a vors 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.
