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: "Create a directory called moodledata somewhere on the disk."

A block of code is set as follows:

DatabaseDirectory Z:\clamav\db
DatabaseMirror clamav.edebris.com
DatabaseMirror database.clamav.net
NotifyClamd Z:\clamav\clamd.conf

Any command-line input or output is written as follows:

CREATE DATABASE moodle CHARSET 'utf8' COLLATION 'utf8_general_ci';
CREATE USER 'moodle'@'localhost' IDENTIFIED BY 'somepass';

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: "Make sure you check Unattended operation at the bottom".
