purifyeps | creates EPS files usable in TeX and pdfTeX | Mehr ...
While pdfLaTeX has a number of nice features, its primary shortcoming relative to standard LaTeX+dvips is that it is unable to read ordinary Encapsulated PostScript (EPS) files, the most common graphics format in the LaTeX world. purifyeps converts EPS files into a "purified" form that can be read by *both* LaTeX+dvips and pdfLaTeX.
