 RDoc - Documentation from Ruby Source Files:
  * Generates structured HTML and XML documentation from Ruby source
    and C extensions.
  * Automatically extracts class, module, method, and attribute
    definitions. These can be annotated using inline comments.
  * Analyzes method visibility.
  * Handles aliasing.
  * Uses non-intrusive and implicit markup in the comments. Readers of
    the original source needn't know that it is marked up at all.
 .
 This package provides the RDoc tool which uses Ruby 1.8.
