    <title>Description</title>

    <para>

        The <function>help</function> functionality exists to create

        and maintain documentation manuals inside &TCAR;.

    </para>

    <refsection id="scripts-bash-help-description-docentry">

    <title>Documentation Entries</title>

    <para>

        The documentation entry identifies the specific file you want

        to work with inside a documentation manual. The help

        functionality recognizes documentation entries in the

        following two formats:

    </para>

    <variablelist>

    <varlistentry>

    <term>Path style</term>

    <listitem>

    <para>

        This format uses paths to represent the documentation entries

        you want to work with.  This format assumes you are using the

        first path component as chapter and the rest of the path as

        section identifier both inside <quote>tcar-fs</quote>

        documentation manual as parent documentation structure. The

        field related to the part sectioning structure in the

        documentation entry (the second field) is assumed empty, as

        well. For example, if you want to document the directory

        <quote>

        class="directory">trunk/Scripts/Bash/Functions/Help</filename></quote>,

        then you can do it with the following command:

    </para>

    <cmdsynopsis>

    <command>centos-art help --edit trunk/Scripts/Bash/Functions/Help</command>

    </cmdsynopsis>

    </listitem>

    </varlistentry>

    <varlistentry>

    <term>Colon style</term>

    <listitem>

    <para>

        This format uses colons to represent the documentation entries

        you want to work with. In this format, the whole documentation

        entry is divided in fields using colon as separator character.

        Documentation entries written this way use each field to

        specify manual, part, chapter and section identifiers (in this

        order). The section identifier can use a path style or hyphen

        style to separate

        components. For example, if you want to document the directory

        <quote>

        class="directory">trunk/Scripts/Bash/Functions/Help</filename></quote>,

        then you can do it with any of the following commands:

    </para>

    <cmdsynopsis>

    <command>centos-art help --edit tcar-fs::trunk:Scripts/Bash/Functions/Help</command>

    <command>centos-art help --edit tcar-fs::trunk:scripts-bash-functions-help</command>

    </cmdsynopsis>

    <para>

        The documentation manual name specified in the first field of

        a colon style documentation entry, must match the name the

        name of the directory where the documentation manual is stored

        in. By default documentation manuals are written in

        trunk/Documentation/Models/Texinfo or

        trunk/Documentation/Models/Docbook directories, based on

        whether they are written in Texinfo or Docbook documentation

        format. 

    </para>

    <para>

        The match relation between the manual name you provide in the

        documentation entry and the related directory name inside

        &TCAR; is case insensitive. The same is true for all other

        documentation entry fields.

    </para>

    </listitem>

    </varlistentry>

    </variablelist>

    <para>

        From these documentation entry formats, the colon style

        provides more flexibility than path style does. You can use

        documentation entries written in colon style to create and

        maintain different documentation manuals, including the

        <quote>tcar-fs</quote> documentation manual. This is something

        you cannot do with documentation entries written in path style

        because they confine all documentation actions to

        <quote>tcar-fs</quote> documentation manual.

        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 create new documentation manuals inside &TCAR; use the

        following command:

        The first time you execute this command, you will be prompted

        document title, document subtitle, document author, etc.  Once

        this information has been collected the

        <function>help</function> functionality performs some

        Once the documentation structure has been created this way,
