In response to some questions, here is a troff source files that use the
postscript embedding macros I posted recently. I put the ps macros from
my earlier message in /tmp/psmac, the file below in /tmp/pstest, and
gave the command
troff -Tpsc /tmp/pstest > /tmp/pstest.dvi
Notice that the inital %! is not needed. That is done in PB.
If the postscript embedding macros are processed by troff with a printer
type other than -Tpsc (or -Tpostscript), it will print as an empty box
instead of the postscript you want.
