I use the following Makefile machinations:

DATE=3D$(shell git log -1 --format=3D"%cd")
REV=3D$(shell git describe --tags)
S2PS=3Dsed -e "s/date=3D.*$$/date=3D$(DATE)/" -e =
"s/rev=3D.*$$/rev=3D$(REV)/" $< >tmp.sch; \
        $(GSCHEM) -p -o $@ -s print.scm tmp.sch; \
        rm tmp.sch

%.sym.ps : %.sym
        $(S2PS)

%.ps : %.sch
        $(S2PS)

PS2PDF=3Dps2pdf -sPAPERSIZE=3Dletter

%.pdf : %.ps
        $(PS2PDF) $<


With this, I can say =93make some-schematic.pdf=94 and get a pdf file =
with the date and revision taken from the git design repository.
