+* `feedfile` - Can be used to change the name of the file generated for the
+ feed. This is particularly useful if a page contains multiple feeds.
+ For example, set "feedfile=feed" to cause it to generate `page/feed.atom`
+ and/or `page/feed.rss`. This option is not supported if the wiki is
+ configured not to use `usedirs`.
+* `pagenames` - If given instead of `pages`, this is interpreted as a
+ space-separated list of absolute page names ([[SubPage/LinkingRules]] are
+ not taken into account), and they are inlined in exactly the order given:
+ the `sort` and `pages` parameters cannot be used in conjunction with
+ this one.
+* `trail` - If set to "yes" and the [[!iki plugins/trail desc=trail]] plugin
+ is enabled, turn the inlined pages into a trail with next/previous links,
+ by passing the same options to [[ikiwiki/directive/trailitems]]. The `skip`
+ and `limit` options are ignored by the trail, so the next/previous links
+ traverse through all matching pages.
