The RHG is a book that explains how the ruby interpreter (the official C implementation of the Ruby language) works internally.
It is partially translated from Japanese. Official RHG contains only 4 chapters.
The IRHG Project has been significantly improved by the integration of the Ruby Forge Translation Documents. The two projects have been merged and have provided a improved format, especially with the addition of color graphics.
All front-end pages and chapters 1 through 10, and chapter 18 have been completed.
Chapter11 is partially completed.
Part of chapter 11, chapters 12 through 17, and chapters 19 and 20 are presently in machine translated form. Due to the use of Google Translation API's, these are much more readable than previously.
