+ * Adds an AsciiDoc inline macro named package that provides a shorthand syntax for linking to the
+ * page on Fedora apps for the specified Fedora package.
+ *
+ * This macro produces links that use the base URL https://apps.fedoraproject.org/packages by
+ * default. That URL can be overridden by defining the document attribute named
+ * uri-package-url-format. The %s token in the value of that attribute gets replaced by the name of
+ * the package.
+ *
+ * Example:
+ *
+ *   package:asciidoctor[]
