+Alter links to traceability items
+=================================
+
+If the item ID matched by *TRACEABILITY_ITEM_ID_REGEX* is incorrect, e.g. it does not exist in the collection of
+traceability items, you can configure the plugin to link to the desired item ID instead.
+Add the item ID returned by Coverity as a key to the Python dictionary *TRACEABILITY_ITEM_ID_REGEX* and the desired
+item ID as value.
