+Description
+-----------
+
+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.  The trick
+is that the standard LaTeX2e graphics packages can parse
+MetaPost-produced EPS directly.  Hence, purifyeps need only convert an
+arbitrary EPS file into the same stylized format that MetaPost
+outputs.
+
+Documentation is provided in Unix man-page format and in PDF
+(U.S. letter-sized).  In addition, executing "purifyeps --help" gives
+basic command-line usage.
+
+
+Requirements
+------------
+
+To run purifyeps, you will need the following:
+
+   * Perl     (http://www.cpan.org)
+
+   * pstoedit (http://www.pstoedit.net/pstoedit)
+
+   * a LaTeX distribution that includes MetaPost (mpost)
+
+purifyeps itself is a Perl script.  On certain operating systems, you
+may need to rename purifyeps (e.g., to purifyeps.pl) to notify the
+system that purifyeps is, in fact, a Perl script.
