orders can be specified.
* `age` - List pages from the most recently created to the oldest.
+
* `mtime` - List pages with the most recently modified first.
-* `title` - Order by title.
-* `title_natural` - Only available if [[!cpan Sort::Naturally]] is
- installed. Orders by title, but numbers in the title are treated
+
+* `title` - Order by title (page name).
+[[!if test="enabled(sortnaturally)" then="""
+* `title_natural` - Orders by title, but numbers in the title are treated
as such, ("1 2 9 10 20" instead of "1 10 2 20 9")
+"""]]
+[[!if test="enabled(meta)" then="""
+* `meta(title)` - Order according to the `\[[!meta title="foo" sortas="bar"]]`
+ or `\[[!meta title="foo"]]` [[ikiwiki/directive]], or the page name if no
+ full title was set. `meta(author)`, `meta(date)`, `meta(updated)`, etc.
+ also work.
+"""]]
+
+In addition, you can combine several sort orders and/or reverse the order of
+sorting, with a string like `age -title` (which would sort by age, then by
+title in reverse order if two pages have the same age).
