Conventions

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.

There are three styles for code. Code words in text are shown as follows: "Notice that we have added only the keywords contrib and non-free after our repository definitions".

A block of code will be set as follows:

# /etc/apt/souces.list
deb http://ftp.br.debian.org/debian/ etch main contrib non-free
deb-src http://ftp.br.debian.org/debian/ etch main contrib non-free

When we wish to draw your attention to a particular part of a code block, the relevant lines or items will be made bold:

<?xml version="1.0" encoding="UTF-8"?>
<Context path="/serMyAdmin">
  <Resource auth="Container" driverClassName="com.mysql.jdbc.Driver" maxActive="20" maxIdle="10" maxWait="-1" name="jdbc/openser_MySQL" type="javax.sql.DataSource" url="jdbc:mysql://localhost:3306/openser" username="sermyadmin" password="secret"/>
</Context>

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

openser:/usr/src# cp mysql-connector-java-5.1.5/mysql-connector-java-5.1.5-bin.jar /usr/local/tomcat6/lib

New terms and important words are introduced in a bold-type font. Words that you see on the screen, in menus or dialog boxes for example, appear in our text like this: "To register a new user, in the login screen simply click on the Register Button".
