What do these 2 lines mean from the default Contribute robots.txt file?

User-agent: googlebot
Disallow: *.csi

[wickahead]

So the robots.txt file tells the search engine not to index certain files, so I
am hypothesizing that the robots.txt file is telling the googlebot spider not
to index files with the extension .csi . I don't exactly know what type of
files .csi are though.

My guess is that they are temporary files used in some of the drafting stuff
where you wouldn't want the incomplete content to be indexed.

My $0.02 worth.
