This LaTeX package provides a new way to use Postscript commands (e.g., PSTricks graphics, PSfrag replacements, EPS graphics) inside a pdfLaTeX processed document. You need recent versions of the LaTeX packages preview, ifpdf, `ifvtex' and a new LaTeX base installation. All Postscript related commands, including `\usepackage', must be a parameter of the `PSforPDF' macro. For details see the test file `ps4pdf-test.tex'. The PDF document is generated via dvips and ps2pdf.
