- .UL troff
- is a text-formatting program for driving the Graphic Systems
- phototypesetter on the
- .UX
- and
- .UC GCOS
- operating systems.
- This device is capable of producing high quality
- text;
- this paper is an example of
- .UL troff
- output.

- 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.

- 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
- is identical to
- .UL troff ,
- so this document also serves as a tutorial on
- .UL nroff .
