# ullrcorners: draw corners on the upper left and lower right sides of a word

The package **ullrcorners** provides a command to surround a word or a
sequence or words by small corners on the upper left and lower right
sides. The typographical convention is inspired by *Mastering Regular
Expressions*, by Jeffrey E. F. Friedl (O'Reilly Media, 2006), where it
is used to delimit regular expressions.
