I am not kidding. There is a lot of documentation you don't appear to have
consulted. It resides here: http://kenn.frap.net/ocamlconf/docs.html/
It is not amazing, but much better than before.
I'm quite sold on Skaller's idea of the whole build process being a
general-purpose program, and I'm trying to supply an API that make that easier,
plus the trivial service of making a portable script out of your O'Caml
program. Since ocamlconf is *mostly* an API, the ocamldoc output is the most
valuable reference.

Excerpt from http://kenn.frap.net/ocamlconf/docs.html/Conf.html
val configure : (configuration_item * bool) list -> t
Takes a configuration_item list, supplemented with a bool to say whether to show
each item to the user, and returns the configuration that results from all the
tests.
To further clarify, when a user types './configure --help' the boolean
determines whether they see the item so you can have behind-the-scenes work.

There are no C-oriented tests, because that is a tough problem with better
solutions than I have time for. If your project is C-heavy, I'd recommend
either:
(1) using autoconf all the way
(2) gluing autoconf to ocamlconf - much easier than reimplementing autoconf
(3) contribute code :-)
I hope eventually to make it easy to glue ocamlconf and autoconf together, but I
do not intend to touch the C library/header issue. I'm always open to concrete
suggestions and/or code.

I haven't found the time to write a narrative tutorial, so until I do I have to
limit my target audience to people who are familiar with autoconf's concepts,
and/or are willing to read reference documentation.

I do like to write documentation :-) but it takes a lot of time, and so mostly I
annotate my sources so ocamldoc can do the work for me. In addition, the API
for ocamlconf is very unstable (note the small number of releases, and low
version number), so it would be a waste of time to put together a tutorial just
to rewrite the API.

In summary:
(1) The "documentation" does not mean "the README and examples", it means the
API docs
(2) I want to write a tutorial eventually, but
(3) I don't have time
(4) The API is not stable enough to merit it
(5) OCamlConf knows how to build mixed C/O'Caml programs, but not how to search
for C libraries.
I understand your frustration, and my answer is that eventually it may be what
you want.
