+elements from a LaTeX source, like formulas or graphics, into separate
+pages of a DVI file.  A flexible and convenient interface allows it to
+specify what commands and constructs should be extracted.  This works
+with DVI files postprocessed by either Dvips and Ghostscript or
+dvipng, but it also works when you are using PDFTeX for generating PDF
+files.")
