Пакет heirloom-doctools: Информация

The Heirloom Documentation Tools provide troff, nroff, and related
utilities to format manual pages and other documents for output on
terminals and printers. They are portable and enhanced versions of
the respective OpenSolaris utilities, which descend to ditroff and
the historical Unix troff. troff provides advanced typographical
features such as kerning, tracking, and hanging characters. It can
access PostScript Type 1, OpenType, and TrueType fonts directly.
Internationalized hyphenation, international paper sizes, and UTF-8
input are supported.
