67       instead of init.
68    
69       In Drupal 6, there are now two hooks that can be used by modules to execute code
70       at the beginning of a page request. hook_boot() replaces hook_boot() in Drupal 5
71       and runs on each page request, even for cached pages. hook_boot() now only runs
72       for non-cached pages and thus can be used for code that was previously placed in
73       hook_menu() with $may_cache = FALSE:
74    
75       Dynamic menu items under a '!$may_cache' block can often be simplified
76       to remove references to arg(n) and use of '%<function-name>' to check
77       conditions. See http://drupal.org/node/103114.
78    
79       The title and description arguments should not have strings wrapped in t(),
80       because translation of these happen in a later stage in the menu system.
