I agree with Ben about Macleans' readme files, and with all the comments. I still think this amounts to vandalism, whatever the reason it was done. In the UK vandalism is termed criminal damage, and prosecuted as such if the perpetrator is caught. I sincerely hope this person is caught and dealt with.

The greatest part of wisdom is learning to develop  the ineffable genius of extracting the "neither here nor there" out of any situation...."
