-## 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.
