    <para>

        In this manual, certain words are represented in different

        fonts, typefaces, sizes, and weights. This highlighting is

        systematic; different words are represented in the same style

        to indicate their inclusion in a specific category. The types

        of words that are represented this way include the

        following:

    </para>

    <variablelist>

        <varlistentry>

        <term><command>command</command></term>

        <listitem>

        <para>

            Linux commands (and other operating system commands, when

            used) are represented this way.  This style should

            indicate to you that you can type the word or phrase on

            the command line and press <keycap>Enter</keycap> to

            invoke a command.  Sometimes a command contains words that

            would be displayed in a different style on their own (such

            as file names). In these cases, they are considered to be

            part of the command, so the entire phrase is displayed as

            a command.  For example:

        </para>

        <para>

            Use the <command>centos-art render

            trunk/Identity/Images/Themes/TreeFlower/4/Distro/5/Anaconda

            --filter="01-welcome"</command> command to produce the first

            slide image used by Anaconda in the branch 5 of &TC;;

            using the version 4 of TreeFlower artistic motif.

        </para>

        </varlistentry>

        <varlistentry>

        <term><filename>file name</filename></term>

        <listitem>

        <para>

            File names, directory names, paths, and RPM package names

            are represented this way. This style indicates that a

            particular file or directory exists with that name on your

            system. Examples:

        </para>

        <para>

            The <filename>init.sh</filename> file in 

            class="directory">trunk/Scripts/Bash/Cli/</filename>

            directory is the initialization script, written in Bash,

            used to automate most of tasks in the repository.

        </para>

        <para>

            The <command>centos-art</command> command uses the

            <filename>ImageMagick</filename> RPM package to convert

            images from PNG format to other formats.

        </para>

        </listitem>

        </varlistentry>

        <varlistentry>

        <term><keycap>key</keycap></term>

        <listitem>

        <para>

            A key on the keyboard is shown in this style.  For

            example:

        </para>

        <para>

            To use <keycap>Tab</keycap> completion to list particular

            files in a directory, type <command>ls</command>, then a

            character, and finally the <keycap>Tab</keycap> key. Your

            terminal displays the list of files in the working

            directory that begin with that character.

        </para>

        </listitem>

        </varlistentry>

        <varlistentry>

        <term><keycombo action="simul"><keycap>key</keycap><keycap>combination</keycap></keycombo></term>

        <listitem>

        <para>

            A combination of keystrokes is represented in this way.

            For example: 

        </para>

        <para>

            The 

            action="simul"><keycap>Ctrl</keycap><keycap>Alt</keycap><keycap>Backspace</keycap></keycombo>

            key combination exits your graphical session and returns

            you to the graphical login screen or the console.

        </para> 

        </listitem> 

        </varlistentry>

        <varlistentry>

        <term><computeroutput>computer output</computeroutput></term>

        <listitem>

        <para>

            Text in this style indicates text displayed to a shell

            prompt such as error messages and responses to commands.

            For example, the <command>ls</command> command displays

            the contents of a directory using this style:

        </para>

<screen>

render_doTranslation.sh     render_getDirTemplate.sh    render_doBaseActions.sh

render_getConfigOption.sh   render_getOptions.sh        render_doThemeActions.sh  

render_getDirOutput.sh      render.sh

</screen>

        <para>

            The output returned in response to the command (in this

            case, the contents of the directory) is shown in this

            style.

        </para>

        </listitem>

        </varlistentry>

        <varlistentry>

        <term><prompt>prompt</prompt></term>

        <listitem>

        <para>

            A prompt, which is a computer's way of signifying that it

            is ready for you to input something, is shown in this

            style. Examples:

        </para>

        <itemizedlist>

        <listitem>

        <para>

            <prompt>$</prompt>

        </para>

        </listitem>

        <listitem>

        <para>

            <prompt>#</prompt>

        </para>

        </listitem>

        <listitem>

        <para>

            <prompt>[centos@projects centos]$</prompt>

        </para>

        </listitem>

        <listitem>

        <para>

            <prompt>projects login:</prompt>

        </para>

        </listitem>

        </itemizedlist>

        </listitem>

        </varlistentry>

        <varlistentry>

        <term><userinput>user input</userinput></term>

        <listitem>

        <para>

            Text that the user types, either on the command line or

            into a text box on a GUI screen, is displayed in this

            style. In the following example,

            <userinput>text</userinput> is displayed in this style: To

            boot your system into the text based installation program,

            you must type in the <userinput>text</userinput> command

            at the <prompt>boot:</prompt> prompt.

        </para>

        </listitem>

        </varlistentry>

        <varlistentry>

        <term><replaceable>replaceable</replaceable></term>

        <listitem>

        <para>

           Text used in examples that is meant to be replaced with

           data provided by the user is displayed in this style. In

           the following example,

           <replaceable>version-number</replaceable> is displayed in

           this style: The directory for the kernel source is

           class="directory">/usr/src/kernels/<replaceable>version-number</replaceable>/</filename>,

           where <replaceable>version-number</replaceable> is the

           version and type of kernel installed on this system. 

        </para>

        </listitem>

        </varlistentry>

    </variablelist>

    <para>Additionally, we use several different strategies to draw

    your attention to certain pieces of information. In order of

    urgency, these items are marked as a note, tip, important,

    caution, or warning. For example:</para>

    <note>

        <para>Remember that Linux is case sensitive. In other words, a

        rose is not a ROSE is not a rOsE.</para>

    </note> 

    <tip>

        <para>The directory 

        class="directory">/usr/share/doc/</filename> contains

        additional documentation for packages installed on your

        system.</para>

    </tip>

    <important>

        <para>If you modify the DHCP configuration file, the changes

        do not take effect until you restart the DHCP daemon.</para>

    </important>

    <caution>

        <para>Do not perform routine tasks as root — use a

        regular user account unless you need to use the root account

        for system administration tasks.</para>

    </caution>

    <warning>

        <para>Be careful to remove only the necessary partitions.

        Removing other partitions could result in data loss or a

        corrupted system environment.</para>
