[drupal-docs] cron jobs in the install text

[Anisa]

Okay, so why is this:
=====================
6. CRON TASKS

   Many Drupal modules have periodic tasks that must be triggered by a
   cron job.  To activate these tasks, you must call the cron page;
   this will pass control to the modules and the modules will decide
   if and what they must do.

   The following example crontab line will activate the cron script
   on the hour:

   0    *   *   *   *   wget -O - -q http://HOSTNAME/cron.php

   More information about the cron scripts are available in the admin
   help pages and in the Drupal handbook at drupal.org.  Example
   scripts can be found in the scripts/ directory.

=====================

IN the install text?  So many things that make not a lot of sense.  I 
bet most people ignore this.  *I* ignore this.  I don't know how to call 
this cron page, or where to put that goobledegook to activate a cron 
script.  Actually, and this is the first time I have even noticed the 
admin help pages, where is this help for the cron script?  There is more 
explanation in the handbook, but I think I still don't get it.  ;p  How 
essential is this to drupal working?
