I've got some comments on this; at least two of the people quoted in
that file are bit confused about things.  But those I will send
off-list, as they are not relevant to tech-userlevel.

I don't know what CUPS does.  But our lpr, at least as of the manpage I
quoted the version number of (which was current as of my last update),
doesn't even _have_ explicit arguments for "this is text" or "this is
PostScript", which is my actual beef with it.  (I can deal with
guessing by default, but when the guess (a) is done with an
undocumented algorithm and (b) cannot be overridden, it crosses the
line into "broken" for me.)

Well, s/general/common/ and I'd agree with you.

I just consider it egregiously arrogant, unacceptable, broken,
whatever, for it to provide no way for the human to override that
guess, because it _will_ guess wrong at least sometimes.
