One problem with adding this is that the hpoj installation process
automatically adds an "hpoj" line, so you would end up with a possibly
confusing situation of two such lines, one commented out somewhere in the
middle and another not commented out at or near the end.  If it's done
right, a binary package (such as the hpoj packages in Mandrake 9.0) should
be able to do a similar thing, so this doesn't help all that much and
will cause a similar problem of confusion.  In any case, the hpoj
documentation explains how to modify this file if necessary, for
example, if the installation process doesn't do the right thing.

I think this is more trouble than it's worth.  I'm trying to not have
too many functional linkages from SANE to hpoj, because that makes it
harder for me to make changes in hpoj.

That will happen automatically with the next SANE release.
