Is this different than print/a2ps?

I tried that and it worked fine. I'd suggest surrounding it by ".if exists"
so that you don't get errors when it doesn't exist -- if I do:
PAPERSIZE!= cat /tmp/.media
all:
@echo ${PAPERSIZE}
% make
cat: /tmp/.media: No such file or directory
"Makefile", line 1: warning: Couldn't read shell's output
"Makefile", line 1: warning: "cat /tmp/.media" returned non-zero
but
.if exists(/tmp/.media)
PAPERSIZE!= cat /tmp/.media
.endif
all:
@echo ${PAPERSIZE}
does:
hub% make PAPERSIZE=booga
booga
hub% echo fooga > /tmp/.media
hub% make PAPERSIZE=booga
booga
hub% make
fooga
(watch out for that last one -- it says that the user can override your
file on the make command line...)
