META tags
---------
Technically, these guys aren't tokens, but it is very important that your
event description files contain them.

<META EVENTNAME="..." [CATEGORY="..."]>
  This is the most important thing to include in your event files.  The value
  of EVENTNAME is used as the headline for the event listing.  If it's not
  set, you get a null headline, which makes it impossible for users to click
  on the link to see your event details.

  CATEGORY is optional and specifies the category the event belongs to.  If
  you're going to use the categorization feature, be sure to set this -
  events which don't belong to any category only appear when all categories
  are displayed.  You can also specify a comma-separated list of multiple
  categories.

<META REPEAT="year month dom dow">
  If you're familiar with crontabs, this one should come easily to you.  If
  not, don't worry - it's not that tough.

  Each of the 4 parameters can take a comma-separated list of the following
  types of values:
    * - Match any number
    a number - Match only that number
    num1-num2 - Match any numbers in the range num1 to num2, inclusive
    */num - Match any number divisible by num
    num1-num2/num3 - Match any number in the range num1 to num2 inclusive and
                     divisible by num3

  The parameters are year, month (1 = January), day of month, and day of week
  (0 = Sunday).

  Now some examples:
  REPEAT="* * 1 *" - Event takes place on the first of every month
  REPEAT="* * * 6" - Every Saturday
  REPEAT="*/4 * * *" - Every day during leap years
  REPEAT="* */2 14-20 5" - The first Friday following the second Saturday of
                           all even-numbered months
