Thus we find that the LaTeX +standard <i>article</i> class is represented on disc by a file called +<i>article.cls</i>, while the <i>footmisc</i> package (which +refines <i>article</i>’s definition of footnotes) is represented on +disc by a file called <i>footmisc.sty</i>. +<p>The user defines the class of his document with the +<code>\</code><code>documentclass</code> command (typically the first command in a +document), and loads packages with the <code>\</code><code>usepackage</code> command. A +document may have several <code>\</code><code>usepackage</code> commands, but it may have +only one <code>\</code><code>documentclass</code> command. (Note that there are +programming-interface versions of both commands, since a class may +choose to load another class to refine its capabilities, and both +classes and packages may choose to load other packages.) +<p><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=clsvpkg">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=clsvpkg</a> +</body> |
