@crontab:
 
  SYNTAX: @crontab
          @cron/add
          @cron/add <job name>=<time>/<object>|<attribute>
          @cron/del <job name>

  Wizard Only
 
  <time> is in the format: [month]|[date]|[day of week]|[hour]|[minute]
  <object> must be a dbref
  [month] and [day of week] are alpha entries (Jan, Mar, Tue, Sat, etc), not 
  numeric entries. Case is unimportant (code lcstr's everything before running 
  it through).
  
  Multiple entries inside any crontab category are space separated. (BE VERY 
  CAREFUL WHEN LEAVING THE LAST 2 ENTRIES BLANK! - ANY BLANK MATCHES 
  EVERYTHING!)

  @cron/add includes error checking and will not allow invalid month or day of 
  week entries, or invalid dbrefs (including non-dbrefs like *jeff).
