Groff

GNU's version of nroff and troff. Groff produces output both for printing and plain ASC text. Macro packages are provided for different types of documents.
Macros:

mgs - Writing papers
man - For writing man pages

To make a man page from a created file(see the section on how to make a man page) type:

groff -t -man -Tascii viewmod.txt > viewmod.1

-Tascii Procuces ASCII text -Tps Produces postscript -Tdvi Output similar to TeX (DVI - Device Independent)

TEX and LaTeX

LaTeX is a set of macros on top of TEX that is concerned with the structure of a document such as chapters, footnotes and sections.
TEX Commands:

\documentstyle{letter}		Choices: article, report, book, letter. They specify global macros
\begin		Begin document
\End		End document
\\		Line break
\		Starts a command, If backslach is trailing, a space is forced
~		Forces a space between tow words or characters without a line break
{\em }		Text within brackets is emphasized
\bf		Boldfaced
\tt		Typwriter text

Example:

\documentstyle{letter}
\address{123 Desert Rd \\Unit 2B\\Wayside, AZ  08821}
\signature{John Smith}
\begin{document}
\begin{letter}{Mr.~George~Lunuxuser\\
		1100 N East Street \\
		California, MD  20190}
\opening{Dear George,}
I would like to inform you that I have just discovered \LaTex\ and it is the greatest
thing since sliced bread.  You should use it for all your text processing needs.
\closing{Most Sincerely,}
\end{letter}
\end{document}

Save as tolinux.tex
Type "latex tolinux"
Results are output in tolinux.dvi

Use "dvips" to make a postscript file from the dvi file, Ex: dvips –o tolinux.ps tolinux.dvi
To see the output, you can use "xdvi" from X windows.
The program "dvilj" will print dvi files on Laserjet printers.
The program "eps" will print dvi files on epson printers.

Texinfo

Used to produce hypertext info pages and printed manuals.

@ - Begins a command
@c or @comment - Begins a comment
@setfilename - Name of output file
@settitle - The title of the document
@setchapternewpage - Tells where to start new chapters. Choices: odd, even
@code - Specifies text to be emphasized
@ifinfo - Specified text to show up only in info file
@enumerate
@end - Way to end things like ifinfo, titlepage, menu, enumerate
@table
@var - Indicates a metavariable
@xref - Cross reference to another node
@cindex - Makes entries in the concept index at the end of the document

Example file:

\input texinfo @c -*-texinfo-*-
@c %**start of header
@setfilename test.info
@settitle An example texinfo file
@c %**end of header

@titlepage
@sp 10
@comment This is to be in large font
@center @titlefont(This Test Title)
@end titlepage

@c	       Node, Next            , Previous, Up
@node Top , First Chapter , (dir), (dir)
@ifinfo
This is a test info file.  There is no worthwhile text here.
This is only a test.
@end ifinfo

@menu
* First Chapter::   	The only chapter
* Concept Index::	Index of Concepts
@end menu

@c		Node             , Next               ,previous, up
@node	First Chapter, Concept Index, Top, Top
@chapter First Chapter
@cindex Sample index entry

@c A numbered list
@enumerate
@item
The first one
@item
The second one
@end enumerate

The @code{makeinfo} and @code{texinfo-format-buffer}
commands transform a Texinfo file into an Info file.  @TeX{}
typesets it for a printed manual.

@c		Node              ,next , previous         , up
@node	Concept Index,       ,  First Chapter, Top
@unnumbered Concept Index

@printindex cp

@contents
@bye

If the file is called test.texi, type "makeinfo test.texi" to make an info file called test.info.
