That will get you the document
which is an excellent summary, and gives pointers to more information.
I think the key sentence that Kari is looking for is this:
The presence of an empty "/robots.txt" file has no explicit associated
semantics, it will be treated as if it was not present, i.e. all robots
will consider themselves welcome.
I.e., by default, search engines should have wide open access to your
site, and it's up to you to disallow certain URLs to certain agents,
if you so desire. If you don't have a robots.txt, and a particular
engine can't spider through your site, but a web browser can manually
access all the documents you want by following HTML links, it's likely
a flaw in that engine. Note that I specifically said HTML links.
