I upgraded ghostscript today. And for some reason, my printing started
using A4 (instead of letter). (I can't remember if I hard-coded that long
ago.) Anyways, it was an easy workaround to use -sPAPERSIZE with my gs
wrapper.

I made a patch for papersize package to support ghostscript.

 $ getpapersize
 a2ps has default papersize: A4
 ghostscript has default papersize: (unknown)
 $ setpapersize letter ghostscript
 Set ghostscript package default paper size to Letter in
 /usr/pkg/share/ghostscript/6.01vflib/lib/gs_init.ps
 $ getpapersize
 a2ps has default papersize: A4
 ghostscript has default papersize: letter

I am looking at /usr/pkg/share/ghostscript/6.01vflib/lib/gs_init.ps.
It says the default is letter. The alternative a4 line is commented out.

The package build has:
.if defined(PAPERSIZE) && (${PAPERSIZE} == "A4" || ${PAPERSIZE} == "a4")
CFLAGS+=                -DA4
.endif

And I see that A4 is set in mk/bsd.pkg.defaults.mk so was built that way.

It looks like some of the patches hard-code A4 also.

Wouldn't it be easier to use the gs_init.ps file?

Also, how should I figure out location of gs_init.ps (because
${GS_VERS}vflib may change)?

My patch for papersize below my signature. Please share your comments.

By the way, setpapersize(1) should:
- check for success before overwriting current configs;
- probably should use some mktemp for temp files;
- only output that it was Set if really set.
And getpapersize(1) should say unknown if unknown.
