everypage – Provide hooks to be run on every page of a document

The pack­age pro­vides hooks to per­form ac­tions on ev­ery page, or on the cur­rent page. Specif­i­cally, ac­tions are per­formed af­ter the page is com­posed, but be­fore it is shipped, so they can be used to pre­pare the out­put page in tasks like putting wa­ter­marks in the back­ground, or in set­ting the next page lay­out, etc.
