+If a parsed document has a `@书社:destination` which contains `%s`,

+Pages are, from Make’s point of view, untracked side·effects of
+  installing the main output, meaning they cannot be targeted directly
+  and will not appear in `make list` or `make listout`.
+They are intended solely for the like of indices and feeds, for which
+  convenience and necessity outweigh their flaws.
