Hello,

Is there a concise introduction/coverage of Ruby similar to how
Kernighan & Ritchie did for C?

I am quite comfortable with programming, and I am currently reading
"Programming Ruby" which I like, but it seems too much. Ie it makes
Ruby seem like a very big language, perhaps it actually is?

I don't just want a simple reference, but something with a concise
tutorial along the lines of K&R. Is there such a book?

Thanks,
Esmail

ps: Ruby in a Nutshell seems a bit outdated and hasn't gotten very
     good reviews.
