What is the difference between the Posix and Cobalt skin, as far as xeno-co=
nfig is concerned??

Difference between
  xeno-config --skin posix --cflags
  xeno-config --skin cobalt --cflags
is that the former declares -D__COBALT_WRAP__ (which in turn adds fwd decla=
rations for clock_nanosleep() and pthread_setname_np() in boilerplate/libc.=
h).

difference between=20
  xeno-config --skin posix --ldflags
  xeno-config --skin cobalt --ldflags
is that the former adds `-Wl,@/usr/xenomai/lib/cobalt.wrappers`

So it seems to me that `--skin posix` expects you to call, e.g.: pthread_cr=
eate(), while `--skin cobalt` expects you to call, e.g.: __wrap_pthread_cre=
ate()

Is this correct?
Is that it?
What are the intended uses?
I don't think this is documented anywhere? Where would be the best place to=
 have this written down? Perhaps the --help of xeno-config? Also, while we =
are at it, --skin alchemy vs --skin native and the effect of --compat could=
 use some description.

Best,
Giulio
