There are still several reasons to use the “traditional” way of creating PDF output, namely the sequence LaTeX → DVIPS → PS2PDF. Using pdfLaTeX is onlypossible when the PostScript related code is handled before the pdfLaTeX run. Thus, several packages and/or scripts have been developed which supports EPS images, or general PostScript-relatedcode, in a document which is compiled at least one time with pdfLaTeX:pst-pdf, auto-pst-pdf, pdftricks, epstopdf, pst2pdf, pstools, … All have the same general goal,but each works in a different way. We will demonstrate with severalexamples.
