Mfpic is a scheme for producing pictures from LaTeX commands. 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 put the picture at the point where the original LaTeX commands appeared. Note that the ability to use MetaPost here means that the package works equally well in LaTeX and PDFLaTeX. The authors are Daniel H. Luecking and Geoffrey Tobin. See also mkpic.
