With pdfpic, all .EPS images can also be used even in PDF. When using .PDFPIC instead of .PSPIC, .EPS graphics are automatically used within all devices. A restriction to .PSPIC is quite strange - .PDFPIC with pdfpic.tmac is a must.
I will need the pdfpic.tmac with .PDFPIC especially for glilypond, but not yet today. The macro was written by Peter Schaffter in 2014. So the license should be added by the author, as well as the documentation in the man-page man/groff_tmac.5.man should be improved.. Bernd Warken
