522 Part IV . Running Applications File Description filename.dvi Device-independent output file that can be translated for use by several different types of output devices (such as PostScript). filename.log A log file that contains diagnostic messages. filename.aux An auxiliary file used by LaTeX. The .dvi file produced can be formatted for a particular device. For example, you could use the dvips command to output the resulting .dvi file to your PostScript printer (dvips filename.dvi). Or you could use the xdvi command to preview the .dvi file in X. Creating and Formatting a LaTeX Document Because LaTeX is the most common way of using TeX, this section describes how to create and format a LaTeX document. A LaTeX macro (often referred to as a command) appears in a document in one of the two following forms: string{option}[required] A backslash () followed by a command. (Replace string with the name of the command.) Optional arguments are contained in braces ({}), and required arguments are in brackets ([]). ?{option}[required] A backslash () followed by a single character (not a letter) command. (Replace ? with the command character.) Optional arguments are contained in braces ({}), and required arguments are in brackets ([]). Each command defines some action to be taken. The action can control page layout, the font used, spacing, paragraph layout, or a variety of other actions on the document. The minimum amount of formatting that a LaTeX document can contain is the following: documentclass{name} begin{document} TEXT GOES HERE! end{document} Replace {name} with the name of the class of document you are creating. The text for the file, along with your formatting commands, goes between the begin and end document commands. The best way to get started with LaTeX is to use the LyX editor, which provides a GUI for creating LaTeX documents. It also contains a variety of templates you can use instead of just creating a document from scratch. Figure 20-10 shows an example of the LyX editor.
