+#
+# ParseDate converts a date into an array of values.
+# For example:
+#
+#   require 'parsedate'
+#
+#   ParseDate.parsedate "Tuesday, July 6th, 2007, 18:35:20 UTC"
+#   # => [2007, 7, 6, 18, 35, 20, "UTC", 2]
+#
+# The order is of the form [year, month, day of month, hour, minute, second,
+# timezone, day of the week].

+  # ParseDate.parsedate can also take a second argument, +comp+, which
+  # is a boolean telling the method to compensate for dates with years
+  # expressed as two digits. Example:
+  #
+  #   require 'parsedate'
+  #
+  #   ParseDate.parsedate "Mon Dec 25 00 06:53:24 UTC", true
+  #   # => [2000, 12, 25, 6, 53, 24, "UTC", 1]
