        The <function>render</function> functionality is the interface

        the <command>centos-art.sh</command> script provides to

        standardize the content production tasks inside the working

        copy.

    <screen>centos-art render [OPTIONS] [DIRECTORY]</screen>

    <para>

        The <varname>DIRECTORY</varname> parameter specifies the

        directory path, inside the working copy of &TCAR;, where the

        files you want to process are stored in.  This paramter can be

        provided more than once in order to process more than one

        directory path in a single command execution.  When this

        parameter is not provided, the current directory path where

        the command was called from is used instead.

        The <function>render</function> functionality accepts the

        following options: 

    </para>

    <variablelist>

    <varlistentry>

    <term><option>--quiet</option></term>

    <listitem>

    <para>

        This option supresses all output messages except error

        messages.  When this option is passed, all confirmation

        requests are supressed and a possitive answer is assumed for

        them, just as if the <option>--answer-yes</option> option

        would have been provided.

    </listitem>

    </varlistentry>

    <varlistentry>

    <term><option>--filter="REGEX"</option></term>

    <listitem>

    <para>

        This option reduces the list of files to process inside

        <varname>DIRECTORY</varname> using <varname>REGEX</varname> as

        pattern.  You can use this option to control the amount of

        files you want to render.  The deeper you go into the

        directory structure the more specific you'll be about the

        files you want to render.  When you cannot go deeper into the

        directory structure through <varname>DIRECTORY</varname>

        specification, use this option to reduce the list of files

        therein.

    <varlistentry>

    <term><option>--sync-changes</option></term>

        Synchronizes available changes between the working copy and

        the central repository.

    </varlistentry>

    <varlistentry>

    <term><option>--releasever="NUMBER"</option></term>

    <listitem>

    <para>

        This option expands the =\RELEASE=,

        =\MAJOR_RELEASE=, and

        =\MINOR_RELEASE= translation makers based on

        <varname>NUMBER</varname> value.  Notice that translation

        markers here were escaped using a backslash (\)

        in order to prevent their expansion. Use this option when you

        need to produce release-specific contents, but no release

        information can be retrived from the directory path you are

        currently rendering.

    <varlistentry>

    <term><option>--basearch="ARCH"</option></term>

    <listitem>

    <para>

        This option expands the =\ARCHITECTURE=,

        translation makers based on <varname>ARHC</varname> value.

        Notice that translation markers here were escaped using a

        backslash (\) in order to prevent their

        expansion. Use this option when you need to produce

        architecture-sepecific contents but no architecture

        information can be retrived from the directory path you are

        currently rendering.

    <varlistentry>

    <term><option>--theme-model="NAME"</option></term>

    <listitem>

    <para>

        This option specifies the name of theme model you want to use

        when producing theme artistic motifs. By default, if this

        option is not provided, the <literal>Default</literal> theme

        model is used as reference to produce theme artistic motifs.

        To know what values does the <varname>NAME</varname> variable

        can have, run <command>ls

        ~/artwork/trunk/Identity/Models/Themes</command> command.

    <varlistentry>

    <term><option>--post-rendition="COMMAND"</option></term>

    <listitem>

    <para>

        This option lets you apply a command as post-rendition action.

        In this case, the <varname>COMMAND</varname> represents the

        command-line you want to execute in order to perform in-place

        modifications to base-rendition output.

    <para>

        This option lets you apply a command as last-rendition action.

        In this case, the <varname>COMMAND</varname> argument

        represents the command string you want to execute in order to

        perform in-place modifications to base-rendition,

        post-rendition and directory-specific rendition outputs.

    <title>Description</title>

    <para>

        Inside the working copy of &TCAR;, rendition tasks take place

        inside renderable directories. The rendition itself is

        performed through a serie of rendition flows named

        base-rendition, post-rendition, last-rendition and

        directory-specific rendition.

    </para>

    <para>

        Renderable directories are convenctional locations inside the

        working copy where you can find source files, output files and

        auxiliar files. Source files are used to produce output files.

        Auxiliar files are used to modify the way output files are

        produced from source files (e.g., to produce localized

        output). Auxiliar files are optionals.

    </para>

    <para>

        Renderable directories are made of several directories but

        only the output dirctory path is passed to

        <function>render</function> functionality as

        <varname>DIRECTORY</varname> parameter in the command-line.

        The directories related to source and auxiliar files are

        automatically constructed based on a directory organization

        convenction. This way, the <function>render</function>

        functionality collects all the information it needs to work

        with.

    </para>

    <para>

        Inside the working copy, renderable directories are divided in

        two categories in a way differences between them can be

        preserved. These categories are named <quote>direct

        production</quote> and <quote>theme production</quote>. These

        categories provide the file organization convenction the

        <function>render</function> functionality needs, to produce

        content based on rendition flows.
