Hi,

I have asked for help from the Ocaml team, in #debian-ocaml. Mehdi has
been of great help, and he explained me lots of things. I think I got it
a lot better this time.

I have attached a new patch against the current Xen in SID (eg:
4.1.1-2). What I did is that in the debian folder, once Xen is built
once, you can do: cd debian && ./find_ocaml_libs, and it will print the
content that we should put in debian/libxen-ocam[dev].install.in. That
small shell script is just a hackish helper that I used to make sure I
wouldn't forget any file, so I didn't feel comfortable setting it up at
build time, but I think it's ok to ship it in our source package for
later reference (in case a new OCaml lib is later added in upstream source).

Then, once we got debian/libxen-ocaml.install.in and
debian/libxen-ocaml-dev.install.in, we have dh_ocamlinit that does the
magic of the variable substitutions using sed, and finally dh_install
does the rest.

"dh_ocamlinit -d" takes care of deleting leftovers from dh_ocamlinit.

Altogether, the patch looks a lot cleaner. Thanks for insisting so that
I would do it right, and thanks to Medhi for his help yesterday evening.

Yup, I forgot these. This patch also add them.

I have set debian-ocaml-maint at lists.debian.org as Cc: to this email, in
the hope that the Debian OCaml task force can have a last look on my
work. I'd appreciate comments, and I hope I didn't do mistakes this
time. Please keep in mind that I don't know much about OCaml...
