pstool – Sup­port for ps­frag within pdfLaTeX

The pack­age works in the same sort of way as pst-pdf, but it also pro­cesses the PostScript graph­ics with ps­frag to add la­bels within the graphic, be­fore con­ver­sion. Thus the bun­dle re­places two steps of an or­di­nary work­flow. (Nat­u­rally, the pack­age re­quires that \write 18 is en­abled.)
Ps­tool en­sures that each ver­sion of each graphic is com­piled once only (the graphic is (re-)com­piled only if it has changed since the pre­vi­ous com­pi­la­tion of the doc­u­ment). This dras­ti­cally speeds up the run­ning of the pack­age in the typ­i­cal case (though the first run of any doc­u­ment is in­evitably just as slow as with any sim­i­lar pack­age).
