+## Pagination
+
+It is possible to have a single source file produce multiple output
+  files via `<书社:page>` elements, whose `@name` gives the name of the
+  page.
+If a parsed document has a `@书社:destination` which contains `%s`,
+  the `%s` will be replaced with the `@name` for each `<书社:page>` (and
+  removed for the main output).
+Otherwise, the `@name` is inserted before the first period of the
+  filename (or at the end of the filename for those with no period).
+If `<书社:page>`s do not have a `@name`, they are numbered
+  sequentially.
+The destination of pages must be in the same directory as their parent.
+
+Pagination essentially forms a limited convenience for the more
+  sophisticated technique of creating an archive with ⛩️📰 书社 and
+  then unarchiving it.
+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.
