* Although it would be possible to categorize subcommands in the same way as they are categorized in dsconfig
|
* interactive mode, this generator does not use the categories.
|
* <p>
|
* It would also be possible to generate the sort of information provided by the configuration reference, such that
|
* this reference would not stop at simply listing an option like --set {PROP:VAL}, but instead would also provide
|
* the list of PROPs and their possible VALs. A future improvement could no doubt merge the configuration reference
|
* with this content, though perhaps the problem calls for hypertext rather than the linear structure of a
|
* <refentry>.
|
* <p>
|
* Each individual subcommand results in a <refsect2> element similar to the following.
|
*
|
* <pre>
|
* <refsect2 xml:id="dsconfig-create-local-db-index">
|
* <title>dsconfig create-local-db-index</title>
|
* <para>Creates Local DB Indexes</para>
|
* <variablelist>
|
* <varlistentry>
|
* <term><option>--backend-name {name}
|
* </option></term>
|
* <listitem>
|
* <para>The name of the Local DB Backend</para>
|
* </listitem>
|
* </varlistentry>
|
* <varlistentry>
|
* <term><option>--index-name {OID}</option></term>
|
* <listitem>
|
* <para>The name of the new Local DB Index which will also be used
|
* as the value of the "attribute" property: Specifies the name
|
* of the attribute for which the index is to be maintained.</para>
|
* </listitem>
|
* </varlistentry>
|
* <varlistentry>
|
* <term><option>--set {PROP:VALUE}</option></term>
|
* <listitem>
|
* <para>Assigns a value to a property where PROP is the name of the
|
* property and VALUE is the single value to be assigned. Specify the same
|
* property multiple times in order to assign more than one value to
|
* it</para>
|
* </listitem>
|
* </varlistentry>
|
* </variablelist>
|
* </refsect2>
|
* </pre>
|
*
|
* @param sc
|
* The SubCommand containing reference information.
