+	 * <li>MANY_MANY: e.g. a member has many skills and a skill belongs to a member.</li>
+	 * </ul>
+	 *
+	 * By declaring these relations, CActiveRecord can bring back related objects
+	 * in either lazy loading or eager loading approach, and you save the effort of
+	 * writing complex JOIN SQL statements.
+	 *
+	 * Each kind of related objects is defined in this method as an array with the following elements:
+	 * <pre>
+	 * 'varName'=>array('relationType', 'className', 'foreignKey', ...additional options)
+	 * </pre>
+	 * where 'varName' refers to the name of the variable/property that the related object(s) can
+	 * be accessed through; 'relationType' refers to the type of the relation, which can be one of the
+	 * following four constants: self::BELONGS_TO, self::HAS_ONE, self::HAS_MANY and self::MANY_MANY;
+	 * 'className' refers to the name of the active record class that the related object(s) is of;
+	 * and 'foreignKey' states the foreign key that relates the two kinds of active record.
+	 * Note, for composite foreign keys, they must be listed together, separating with space or comma;
+	 * and for foreign keys used in MANY_MANY relation, the joining table must be declared as well
+	 * (e.g. 'joinTable(fk1, fk2)').
+	 *
+	 * Additional options may be specified as name-value pairs in the rest array elements:
+	 * <ul>
+	 * <li>'select': string|array, a list of columns to be selected. Defaults to '*', meaning all columns.
+	 *   Column names should be disambiguated if they appear in an expression (e.g. COUNT(??.name) AS name_count).</li>
+	 * <li>'condition': string, the WHERE clause. Defaults to empty. Note, column references need to
+	 *   be disambiguated with prefix '??.' (e.g. ??.age&gt;20)</li>
+	 * <li>'order': string, the ORDER BY clause. Defaults to empty. Note, column references need to
+	 *   be disambiguated with prefix '??.' (e.g. ??.age DESC)</li>
+	 * <li>'with': string|array, a list of child related objects that should be loaded together with this object.
+	 *   Note, this is only honored by lazy loading, not eager loading.</li>
+	 * <li>'joinType': type of join. Defaults to 'LEFT OUTER JOIN'.</li>
+	 * <li>'alias': the alias for the table associated with this relationship.
+	 *   This option has been available since version 1.0.1. It defaults to null,
+	 *   meaning the table alias is the same as the relation name.</li>
+     * <li>'params': the parameters to be bound to the generated SQL statement.
+	 *   This should be given as an array of name-value pairs. This option has been
+	 *   available since version 1.0.3.</li>
+	 * <li>'on': the ON clause. The condition specified here will be appended
+	 *   to the joining condition using the AND operator. This option has been
+	 *   available since version 1.0.2.</li>
+	 * </ul>
+	 *
+	 * The following options are available for certain relations when lazy loading:
+	 * <ul>
+	 * <li>'group': string, the GROUP BY clause. Defaults to empty. Note, column references need to
+	 *   be disambiguated with prefix '??.' (e.g. ??.age). This option only applies to HAS_MANY and MANY_MANY relations.</li>
+	 * <li>'having': string, the HAVING clause. Defaults to empty. Note, column references need to
+	 *   be disambiguated with prefix '??.' (e.g. ??.age). This option only applies to HAS_MANY and MANY_MANY relations.</li>
+	 * <li>'limit': limit of the rows to be selected. This option does not apply to BELONGS_TO relation.</li>
+	 * <li>'offset': offset of the rows to be selected. This option does not apply to BELONGS_TO relation.</li>
+	 * </ul>
+	 *
