title: Drupal 7: Hook for Node processing before page loaded
body: <p>I am in Drupal 7 and want to do some side processing, i.e. neither to affect the fields nor the themeing, on a node, before the node's page is rendered. In other words, I want to implement in a custom module an 'appropriate hook' so that I can pick-up node's info. Again the implementing function I want to be executed in .module file rather than in template.php.
  Thanks</p>
