Ok, let's end the ballistic game. I think Gilles is very concerned by
the fact that introducing inconsistencies or any ambiguity in downstream
packages will certainly backfire upstream, with endless posting on the
xenomai mailing lists from users being lost in space. Which makes sense.

Personally, I would really recommend to move the Xenomai stuff in its
own sub-dir whenever possible, as a first remedy; requiring PATH update
is much better than forking the Xenomai namespace.
In the future, maybe we could simply provide a wrapper script accepting
sub-commands, such as "xeno latency, xeno sigtest" etc, to be put
into /usr/bin by distros, which would hide the actual location of those
binaries?

In any case, thanks for your work so far. We probably need to discuss
the packaging issues on this list, so that we get both consistency and
usability in the future.

Gilles and Roland, if this is fine with you, I'll handle the liaison
role with upstream packagers, so please CC me explicitly on those mails.
We'll sort out this issue, it doesn't look that bad anyway.
