building ocsigen documentation and building doc from .eliom files

[MdeLv]

Following #594 and ocsigen/graffiti#11, can you tell us:

1/ how to build eliom documentation from its source with eliomdoc?
And for ocsigenserver, js_of_ocaml, tyxml as well?

2/ how to build the documentation of a program from its .eliom[i] and .ml[i] files?
man eliomc references http://ocsigen.org/eliom/manual/workflow-compilation which is a broken link (btw, this needs to be fixed).
However, this link is available: https://ocsigen.org/eliom/6.6/manual/workflow-compilation#h5o-5 .

I could preprocess a few .eliom files
$ eliompp -server foo.eliom

However, the following outputs nothing:

$ eliompp -client foo.eliom
# 1 "foo.eliom"
# 1 "<command-line>"
# 1 "foo.eliom"

while there are some let%client and let%shared definitions in foo.eliom .
It's not normal because there are client definitions and because shared definitions are supposed to be duplicated as server and client declarations.
How to fix that?

I could not use
$ eliomdoc -client -d doc/client -html foobar.eliom Fatal error: exception Fl_package_base.No_such_package("js_of_ocaml-camlp4", "required by eliom.syntax.predef'")
I tried the following commands with no success:
$ eliomdoc -pp eliompp -client -d doc/client -html foobar.eliom
$ eliomdoc -pp eliompp -package js_of_ocaml-camlp4 -client -d doc/client -html foobar.eliom $ eliomdoc -ppx eliompp -client -d doc/client -html foobar.eliom`
...
Where is js_of_ocaml-camlp4 or remplacement available? (ppx?)
How to do?

Thanks
