   Sys.getcwd : unit -> string


If I understood correctly, it is more about the directory of the module at
compile time.

One (hackish) way to do it is with the value __FILE__  in Pervasives (see
http://caml.inria.fr/pub/docs/manual-ocaml/libref/Pervasives.html#6_Debugging
for some compile time constant used for debugging).
It simply returns the path of the .ml given to the compiler, not an
absolute path (except if you called the compiler on an absolute path, of
course).

I do not think there is any way to get the current directory of an
implementation at compile time otherwise.
