Chapter 20 . Working with Words and Images 509 . Scientific notation is supported. With geqn, you can create complex equations. LaTeX and TeX are suited for technical notation, and some math publications require LaTeX. . Editing can be faster because traditional Linux documents are created with a text editor. You usually get better performance out of a text editor than a word processor. Simple page layouts work well with Linux documentation tools. For example, a technical book with a few flow charts and images can be easily produced and maintained using Groff or TeX documentation tools. Letters and memos are also easy to do with these tools. And, of course, Linux man pages are created with text-based tools. Additionally, Linux likes PostScript. Although people think of PostScript as a printing language, it is really more of a programming language (you could write PostScript code directly). Most Linux document-processing software includes print drivers for PostScript. Some documents on the Web are distributed in PostScript (.ps). The drawback to the traditional Linux document tools is that they are not intuitive. Although there are some easier front ends to LaTeX (see the description of LyX later in this chapter), if you are creating documents in a text editor, you need to learn what macros to type into your documents and which formatting and print commands to use. For many years, the UNIX system documentation distributed by AT&T was created in troff/nroff formats, which predate Groff. The documents used separate macro packages for man pages and guide material. Using a source code control system (SCCS), thousands of pages of documentation were ported to different UNIX systems. Creating Documents in Groff or LaTeX You can use any text editor to create documents for both Linux s Groff (troff/nroff) and LaTeX (TeX) styles of publishing. Most Linux distributions come with several text editors. You always have the option to download others from the Internet. (See the Choosing a Text Editor sidebar for more information.) Here are the general steps for creating documents in Groff or LaTeX: 1. Create a document with any text editor. The document will contain text and markup. 2. Format the document using a formatting command that matches the style of the document that you created (for example, with groff or latex). During this step, you may need to indicate that the document contains special content, such as equations (eqn command), tables (tbl command), or line drawings (pic command). Note
