Here's my first attempt at writting directions for installing the
gdev820c.c driver into ghostscript.  These are the steps I used
under Slackware Linux.  Your millage will vary.  I (hopefully)
will be writting a little more verbose version of this in the future.

untar ghostscript-3.33
cd gs3.33
untar ghostscript-3.33jpeg
(for 5.10 untar libpg and zlib too)

Edit gcc-head.mak
    set XLDFLAGS= to -L/usr/X11/lib
    add djet820c.dev onto DEVICE_DEVS3

Edit devs.mak
    Add:
----cuthere----
# djet820c H-P DeskJet 820C
gdev820c.$(OBJ): gdev820c.c $(PDEVH)

djet820c_=gdev820c.$(OBJ) gdevprn.$(OBJ)
djet820c.dev: $(djet820c_)
	$(SETDEV) djet820c $(djet820c_)
----cuthere----
NOTE: the last line must start with a single tab character, not spaces

sh tar_cat
ln -s unix-gcc.mak makefile
make

For 3.33 untar fonts into /usr/local/lib/ghostview/fonts.
For 5.10 untar fonts into /usr/local/share/ghostview/fonts.
