http://Drupal.org.in has published Drupal 4.7 code documentation. It uses phpxref version of documentation. Referenced Drupal code is available as part of doc.Doc is searchable for classes, function, variable and constants used in code. It will be valuable resource for Drupal beginner. Experienced developers may take advantage of the doc as reference material for module developments. The doc will be also a good resource for any new php programmer as reference material.
Also, if developers find it useful, I request mods/admin to add the link on their development website.
