Hello People,
I have written a free to use Ruby book http://is.gd/fYNuH
Hope you people read it and give your suggestions.
To be honest, that's a good effort.
I'd suggest removing the reference that 'eval("string")' is a good way
of making symbols - I'd use "string".intern instead 
And just after that, you use loads of symbols with capitalised initial
letters - not ideal naming convention. Otherwise, pretty good (I even
learnt about "shebang" which I had not know before 
Thanks for your feedback. Will try to correct as soon as possible.
