PSfrag is a LaTeX package that allows one to overlay Encapsulated PostScript (EPS) figures with arbitrary LaTeX constructions, properly aligned, scaled, and rotated.
PSfrag will remove the tag and replace it by the specified LaTeX construction.
The authors of PSfrag are Craig Barratt, Michael Grant and David Carlisle.
PSfrag is not pdf-compatible, but there exist external solutions, like pstool, pst-pdf or pdfrack.
