Depends on the import tool used. For simple cases (which I'm pretty sure
all the hurdextras translators are), git-cvsimport does fine -- and this
one works perfectly well with only anonymous CVS access.

Yeah, I think so. No point in lumping them together...

(IMHO, all the interesting translators should actually go into the main
Hurd tree -- but there is no consensus about that; and also, most of the
hurdextras translators don't have copyright assignments, and thus can't
really go into the main tree :-( )

The obvious thing is the --help output: it misses many formats and
fields. Looking at the source code was the only way for me to find out
how to get the information I need...

IIRC while looking at this part of the code, I also discovered some
other things that are messy -- but I don't remember the details anymore.

Hm... I wonder whether we shouldn't just drop that code. It probably
hasn't been used in something like 15 years...

(The initial development -- before the Hurd was self-hosting -- was done
using a different Mach-based system for hosting, and running the Hurd
servers next to them while debugging. Other remnants of that are the
"ux" bits in "boot".)

Nah, that's not meant as a TODO item I think. By the sound of it, it's
just a fallback, in case of things going wrong outside the control of ps
itself... Haven't actually checked the code though.
