.PP

|
.UL troff
|
|
is a text-formatting program for
|
|
typesetting on the
|
|
.UX
|
|
operating system.
|
|
This device is capable of producing high quality
|
|
text;
|
|
this paper is an example of
|
|
.UL troff
|
|
output.
|
|
.PP
|
|
The phototypesetter itself normally runs with four fonts,
|
|
containing roman, italic and bold letters
|
|
(as on this page),
|
|
a full greek alphabet, and a substantial number of
|
|
special characters and mathematical symbols.
|
|
Characters can be printed in a range of sizes,
|
|
and placed anywhere on the page.
|
|
.PP
|
|
.UL troff
|
|
allows the user full control over fonts,
|
|
sizes, and character positions,
|
|
as well as the usual features of a formatter _
|
|
right-margin justification, automatic hyphenation,
|
|
page titling and numbering, and so on.
|
|
It also provides macros, arithmetic variables and operations,
|
|
and conditional testing, for complicated formatting tasks.
|
|
.PP
|
|
This document is an introduction to the most basic use of
|
|
.UL troff .
|
|
It presents just enough information to enable the user
|
|
to do simple formatting
|
|
tasks like making viewgraphs,
|
|
and to make incremental changes to existing packages
|
|
of
|
|
.UL troff
|
|
commands.
|
|
In most respects, the
|
|
.UC UNIX
|
|
formatter
|
|
.UL nroff
|
|
and a more recent version
|
|
.ul
|
|
(device-independent
|
|
.UL troff)
|
|
are identical to
|
|
the version described here, so this document also serves as a tutorial for
|
|
them as well.

\fB\s+1NOTE: This document refers to the historical \f(BItroff\fB program, and
|
|
not to \f(BIgroff\fB. This is a first cut at importing the tutorial from
|
|
4.4BSD, now that the code has been released. It should at some time be modified
|
|
to describe \f(BIgroff\fR.\s0
