6acace
        &TCAR; development was eventually stopped at November 2011
6acace
        until July 2012 when it was decided to make the
6acace
        <command>centos-art.sh</command> script a bit more
6acace
        customizable than it presently was. For example, it was
1df8fc
        considered as a need that functionalities inside the
1df8fc
        <command>centos-art.sh</command> script must be not just
1df8fc
        conceived independent one another but reusable in different
1df8fc
        contexts.

6acace
        As consequence of this autonomy we want to have among
6acace
        functionalities, the procedure used to locale messages inside
6acace
        the <command>centos-art.sh</command> script had to be
6acace
        modified in order to accept such pluggable behavior into the
6acace
        script. We cannot have a single
6acace
        <filename>centos-art.sh.po</filename> file for all the
6acace
        functionalities because all functionalities are not used in
6acace
        the same context. Instead, it is required that each
6acace
        functionality has its own 
6acace
        class="extension">messages.po</filename> file in order to
6acace
        treat them individually. Otherwise, we would end up having
6acace
        translations for functionalities that we don't need or use in
6acace
        our current context.

        As an example, consider a situation where you are working on
6acace
        the corporate identity of &TC;; and you need to start a new
6acace
        corporate identity project for another organization. You want
6acace
        to keep the directory structure of &TCAR; and its automation
6acace
        tool, the <command>centos-art.sh</command> script. Your new
6acace
        project requires you to introduce new functionalities to
6acace
        <command>centos-art.sh</command> that don't fit the needs of
6acace
        &TC;; (e.g., you want to introduce a
6acace
        <function>report</function> functionality to mesure how much
6acace
        connect time do you consume through your PPP internface.).
6acace
    </para>
6acace
6acace
    <para>
6acace
        To solve this issue, you need to mix specific parts of
6acace
        different central repositories into one single working copy.
6acace
        This is the working copy you'll use to manage your new
6acace
        project. The <xref linkend="repository-history-2012-1" />,
6acace
        illustrates how the <function>render</function> functionality
6acace
        living in &TCAR; has been integrated into the working copy of
6acace
        your new project.

        At this point you find yourself working with a mix of two
6acace
        different central repositories in the same working copy. One
6acace
        repository provides your organization files. The other
6acace
        repository provides the files of <function>render</function>
6acace
        functionality at &TCAR;.  In this environment, all updates
6acace
        commited to the <function>render</function> functionality at
6acace
        &TCAR; will be available to you too, the next time you update
6acace
        your working copy.

6acace
        Understanding the need of mixing different repositories into a
6acace
        single working copy is an important setp for reusing the
6acace
        functionalities that come with centos-art.sh script, but it is
6acace
        not enough if you want to customize the information produced
6acace
        by it.  By default, the centos-art.sh script uses information
6acace
        related to &TC;;. You probably need to change this if you are
6acace
        producing images to a different organization than &TC;;. For
6acace
        example, some of the information you might need to change
6acace
        would be the copyright holder, brands, domain names, mailing
6acace
        lists, and so forth.  To change this information you need to
6acace
        duplicate the file <filename>centos-art.sh</filename> and
6acace
        rename it to something else. Later, you need to edit the
6acace
        renamed version and change variables inside according your
6acace
        needs. In <xref linkend="repository-history-2012-1" />, we
319720
        used the name <filename>myapp.sh</filename> instead of
6acace
        <filename>centos-art.sh</filename> so the information we set
319720
        inside it could reflect the specific needs that motivated the
6acace
        creation of a new project without affecting those from &TC;;.
6acace
    </para>
6acace
6acace
    <para>
6acace
        Most of the information you need to change in your duplicated
6acace
        version of <filename>centos-art.sh</filename> file is
319720
        controlled by a set of read-only variables. You modify these
6acace
        variables here and they will be available all along the script
6acace
        execution time. For example, you can change the value of
6acace
        <varname>CLI_WRKCOPY</varname> variable inside your duplicated
6acace
        version of <filename>centos-art.sh</filename> to change the
319720
        absolute path you use to store your working copy.
6acace
    </para>
6acace
6acace
    <caution>
6acace
        <para>
6acace
            Setting the absolute path of your working copy to
6acace
            something different than
6acace
            <filename>/home/centos/Projects/artwork</filename> will
6acace
            provoke that some components inside &TCAR; be processed
6acace
            correctly while others don't.
6acace
        </para>
6acace
6acace
        <para>
6acace
            For example, SVG design models will be processed correctly
6acace
            but CSS files won't.  This is because before processing
6acace
            SVG files we expand translation markers inside them create
6acace
            a temporal file and then process the temporal file instead
6acace
            of the original SVG file. In the case of CSS files doing
6acace
            the same isn't appropriate.
