who would set a page so as to get the greatest evenness of word spacing. LaTeX—or rather the
underlying TeX hyphenation-justification algorithm—is able to produce that evenness
automatically (see fig. 1). This has been so successful an implementation of this old technique
that it has been borrowed now for Adobe’s InDesign program, where it is called the multi-line
