+Commands @code{\\mfpic} and @code{\\endmfpic} (in LaTeX, the @code{mfpic}
+environment) enclose a group in which drawing commands may be placed.  The
+commands generate a Meta-language file, which may be processed by MetaPost (or
+even Metafont).  The resulting image file will be read back in to the document
+to place the picture at the point where the original (La)TeX commands
+appeared.")
