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

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

        standardize frequent documentation tasks, based on specific

        documentation formats, as described in 

        linkend="manuals-formats"/>.

    <para>

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

        documentation entry you want to process.  It can be provided

        one or more times in the form

        MANUAL:PART:CHAPTER:SECTION or

        MANUAL::CHAPTER:SECTION based on whether the

        manual documentation backend you are using supports

        structuring through parts or not. When

        <varname>DOCENTRY</varname> parameter is not provided,

        <quote>&TCAR; Repository File System</quote> documentation

        manual is used as default value.

    </para>

    <para>

        To determine the documentation format to use, when new

        documentation manuals are created and no configuration file is

        available, the <function>help</function> functionality request

        you to enter one of the supported documentation formats and

        then, uses it to create the documentation manual. Once the

        documentation manual is created, the document configuration

        file is available inside the manual directory structure and

        used to retrive the document format information, instead.

    <listitem>

    <para>

        Supress 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.

    </para>

    <para>

        The <varname>DOCENTRY</varname> parameter must point to any

        directory inside the working copy.  When more than one

        <varname>DOCENTRY</varname> are passed as non-option

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

        command-line, they are queued for further edition.  The

        edition itself takes place through your default text editor

        (e.g., the one you specified in the <envar>EDITOR</envar>

        environment variable) and the text editor opens one file at

        time (i.e., the queue of files to edit is not loaded in the

        text editor.).

        non-option parameter is considered the source location and the

    <para>

        When documentation entries are renamed, it is required to pass

        only two non-option parameters to the command-line. The first

        non-option parameter is considered the source location and the

        second one the target location.  Both source location and

        copy.

    <para>

        When documentation entries are removed (e.g., through

        <option>--delete</option> or <option>--rename</option>

        options), the <function>help</function> functionality takes

        care of updating nodes, menus and cross references related to

        documentation entries in order to keep the manual structure in

        a consistent state.
