.forward file format

[AKA Solitair]

I know the format is vaguely described in the manual (I have it in front
of me), but it doesn't say very clearly if the separate arguments need
to be on the same line or on a line each.

It also doesn't say what happens if you try to pipe something to a
non-existing program (do the other pipes you specified still proceed,
assuming you have specified more than one).  Also I get the impression
that the .forward file doesn't need to be world-readable (like the
manual suggests).  I distinctly get the impression that the piped
programs are executed with your own uid,euid,gid and egid (as if it were
yourself).  Now, is this behaviour a "feature" of SunOS 4.0 or, is it
generic?

I would be very gratefull if anyone could shed some light onto this matter.
