Hi Matz,

I went to Amazon.com to look for Ruby books.  I notice that you have
written "The Ruby Programming Language" book with another "matz" due to be
released for sale in September of this year according to Amazon.  

(BTW, the "logo" on the cover is a ruby stone in the shape of a heart!)

Could you give us a preview of what's in your book ?  Is it more of a
reference type or a complete discussion of the main and advanced features
of Ruby (the internals) or both in the same style as Larry Wall's
"Programming Perl".
