Yes this is extremely usefull, and would be a necessity if you don't want
people to simply install all their stuff in the $OCAMLLIB directory, possibly
overwritting some future addition to the what is put in there by ocaml.

Also, what is the reason the current system does search in the $OCAMLLIB as
well as the current directory for files ? if this was so, we could simply
write :

    ocamlc -c -I labltk -I lablGL gears.ml

and have ocamlc search in the following places (and in this order ?) :

    $OCAMLLIB
    $PWD
    $PWD/labltk
    $PWD/lablGL
    $OCAMLLIB/labltk
    $OCAMLLIB/lablGL

C does something similar with his include files ?

Also another related issue would be to be able to append a modules path
element to libraries when building them. (or maybe this is already possible
?).

It would go like this :

    ocamlc -<some special flag> XXX -a foo.cmo bar.cmo -o xxx.cma 

which would give would put the modules in the xxx.cma library as follows :

   XXX.Bar
   XXX.Foo

instead of :

   Bar
   Foo

Thus permitting people to reuse modules names in their libraries whitout
needing to be carefull with conflict with other similar module names.
