Epstopdf is a Perl script that converts an EPS file to an encapsulated PDF file (a single page file whose media box is the same as the original EPS's bounding box). The resulting file suitable for inclusion by pdfTeX as an image. LaTeX users may make use of the epstopdf package, which will run the epstopdf script on the fly, thus giving the illusion that pdfLaTeX is accepting EPS graphic files.
