It has become popular in the last year or so to criticize people who ask
questions on this list essentially for not already knowing the answer. If you
have lost track of what sort of information a Perl beginner may not know then
you should not be trying to help them. It is entirely possible that the OP had
no knowledge of the built in documentation, or even that he had already read it,
failed to understand it and was looking for a summary from people who were more
familiar with the language. The pompous RTFM reply is precisely what Casey was
trying to put a stop to when he initiated this list.
And I wondered if you were really from the Cocos Islands because your email has
a .cc country code. I spent a couple of weeks there when I last finished working
in India.
