<h3 class="section">1.2 Using Texinfo</h3>

Using Texinfo, you can create a printed document (via the TeX
typesetting system) the normal features of a book, including chapters,
sections, cross references, and indices.  From the same Texinfo source
file, you can create an Info file with special features to make
documentation browsing easy.  You can also create from that same
source file an HTML output file suitable for use with a web browser,
or an XML file.  See the next section (see <a href="Output-Formats.html#Output-Formats">Output Formats</a>) for
details and the exact commands to generate output from the source.

  <p>TeX works with virtually all printers; Info works with virtually all
computer terminals; the HTML output works with virtually all web
browsers.  Thus Texinfo can be used by almost any computer user.

  <p><a name="index-Source-file-format-13"></a>A Texinfo source file is a plain ASCII file containing text
interspersed with <dfn>@-commands</dfn> (words preceded by an &lsquo;<samp><span class="samp">@</span></samp>&rsquo;)
that tell the typesetting and formatting programs what to do.  You can
edit a Texinfo file with any text editor, but it is especially
convenient to use GNU Emacs since that editor has a special mode,
called Texinfo mode, that provides various Texinfo-related features. 
(See <a href="Texinfo-Mode.html#Texinfo-Mode">Texinfo Mode</a>.)

  <p>You can use Texinfo to create both online help and printed manuals;
moreover, Texinfo is freely redistributable.  For these reasons, Texinfo
is the official documentation format of the GNU project.  More
information is available at the <a href="http://www.gnu.org/doc/">GNU documentation web page</a>.
