ocamlbuild and installed modules and libraries

["Daniel Bünzli" <daniel.buenzli@erratique.ch>]

Hello,

Is it possible to specify a single installed module (instead of a lib)  
for link time ? That is is there something like -lib but for module so  
that I can type :

ocamlbuild -I +xmlm -mod xmlm test.native

where test.ml uses the xmlm module

And what about having special tags use_lib_$LIB and use_mod_$MOD that  
automatically create rules to use libraries $LIB.cm(x)a and module  
$MOD.cm(o|x) so that just the appropriate -I to find the files has to  
be specified. In most cases having to use a plugin just for that seems  
overkill. Or is there another way ?

Best,

Daniel
