In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "Go to your theme's .info file."

A block of code is set as follows:

Code [<?php
if (!$page) {
  print "<h2><a href=\"$node_url\">$title</a></h2>";
}

if ($submitted) {
  print "<span class=\"submitted\">$submitted</span>";
}
?>]

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Click on the Clear all caches button located at Administration | Configuration | Development | Performance."
