Some of these +included the New Font Selection Scheme (NFSS), SLITeX (for slides), +AASTeX (the American Astronomical Society macros), etc. The major +change to LaTeX2e is the method for trying to make the use of add-on +packages more uniform by the introduction of "classes" +and "packages." Most of the new commands are the "initial" commands, +i.e., those which can appear only <em>before</em> the +<tt>\documentclass</tt> command.</p> + +<p>A few standard LaTeX commands have been modified and a few new commands +added, notably:</p> + +<ul> + <li><a href="ltx-18.html"><tt>\newcommand</tt></a> (and related) commands, + which now allow for an optional argument in newly defined commands + <li><a href="ensuremath.html"><tt>\ensuremath</tt></a> +</ul> + + +<h2>Document Styles and Style Options</h2> + +<p>In LaTeX2e, documents begin with a <tt>\documentclass</tt> command. This +replaces the LaTeX 2.09 +<a href="ltx-22.html"><tt>\documentstyle</tt></a> command. The +<tt>\usepackage</tt> command has been added and is used in conjunction +with <tt>\documentclass</tt>.</p> + +<p> aTeX2e still understands the old +<a href="ltx-22.html"><tt>\documentstyle</tt></a> command; if it is +encountered, LaTex2e enters <em>compatibility +mode</em> in which most 2.09 input files should still be processed properly.</p> + + +<h2>Type Styles and Sizes</h2> + +<p>LaTeX 2.09 commands for changing type style, for example, <tt>\tt</tt>, +still work similarly in LaTeX2e. +The major difference is that <tt>\sc</tt> and <tt>\sl</tt> +can no longer be used in math mode (except when LaTeX2e is in +<em>compatibility mode</em>, see above).</p> + +<p>However, <a href="fonts2e.html">a new set of commands</a> +have been added to allow separate (and independent) specification of </p> + +<ul> + <li>Shape + <li>Series + <li>Family +</ul> + +<p>These can be combined to form a wide variety of type styles.
