This section focuses on how to invoke the
groff front end. This
front end takes care of the details of constructing the pipeline among
gtroff and the postprocessor.
It has become a tradition that GNU programs get the prefix ‘g’ to
distinguish it from its original counterparts provided by the host (see
Environment, for more details). Thus, for example,
eqn. On operating systems like GNU/Linux or the Hurd, which
don’t contain proprietary versions of
troff, and on
troff and associated programs are not
available at all, this prefix is omitted since GNU
troff is the
only used incarnation of
troff. Exception: ‘groff’ is never
replaced by ‘roff’.
In this document, we consequently say ‘gtroff’ when talking about
troff program. All other implementations of
are called AT&T
troff, which is the common origin of all
troff derivates (with more or less compatible changes).
Similarly, we say ‘gpic’, ‘geqn’, etc.
