It was originally written by Stephen Frede, who now works for some australian company. We use a customized version of his 'tpscript'-package. Our customizations include some improvements concerning the generated PostScript and an extended '\!'-interface. Namely, we added an execution-directive, that allows to 'invoke' any UNIX(1) command and insert it's (standard-)output into the stream of PostScript generated by the postprocessor. This - of course - makes only sense with unix-commands which produce PostScript on standard-out themselves. We use this feature with a program that converts GEM-Metafiles to PostScript. The described approach is not limited to the Metafile-converter, but can be applied to any PostScript-graphic for which bounding-box information is obtainable. We have one single troff-macro that interfaces very conveniently to this mechanism. Axel Mahler, Tech.Univ. Berlin UUCP: axel@coma.uucp (unido!coma!axel) BITNET: axel@db0tui62.bitnet
