Some directives that use PageSpecs allow specifying the order that matching pages are shown in. The following sort 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 (page name).
meta(title) - Order according to the [[!meta title="foo" sortas="bar"]]
or [[!meta title="foo"]] 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).
