The link feature was made to don't loose the user and help him to
understand the _build directory system. However when one become more
experienced I advise to hunt directly in the _build directory.

You can even forbid ocamlbuild to make these links with the flag
-no-links or the option Options.make_links.

In a prototyping/scripting mode running directly them is really nice.

If you want the _log to be in _build, just say it (-log _build/_log).
For the emacs mode since both authors don't use emacs we don't have
ported yet. Damien Doligez will do it but you can also send patches ;)
