GNU troff text-formatting system (base system components)

This package contains the traditional UN*X text formatting tools
troff, nroff, tbl, eqn, and pic. These utilities, together with the
man-db package, are essential for displaying the on-line manual pages.

groff-base is a stripped-down package containing the necessary components
to read manual pages in ASCII, Latin-1, and UTF-8, plus the PostScript
device (groff's default). Users who want a full groff installation, with
the standard set of devices, fonts, macros, and documentation, should
install the groff package.
