The package provides “store boxes” whose user interface matches that of normal LaTeX “save boxes”, except that the content of a store box appears at most once in the output PDF file, however often it is used.

The present version of the package supports pdfLaTeX and LuaLaTeX; when DVI is output, store boxes behave the same as save boxes.
