 = ThirdBase: A Fast and Easy Date/DateTime Class for Ruby
 
 ThirdBase differs from Ruby's standard Date/DateTime class in the following
 ways:
 
-- ThirdBase is roughly 2-12 times faster depending on usage
+- ThirdBase is roughly 2-10 times faster depending on usage
 - ThirdBase has a lower memory footprint
 - ThirdBase supports pluggable parsers
 - ThirdBase doesn't depend on Ruby's Rational class
 - ThirdBase always uses the gregorian calendar

-A ThirdBase Date/Datetime parser consists of two parts, a regular

 Adding a parser to a parser type adds it to the front of the array of parsers 
 for that type, so it will be tried before other parsers for that type.  It is
 an error to add a parser to a parser type that doesn't exist.

+=== Adding strptime Parsers to Parser Types (New in 1.2.0)
+
+ThirdBase 1.2.0 added the ability to more easily create common parsers
+using the strptime format string syntax.  These are created similar to regexp
+parsers, but use a format string, and the block is then optional (and should
+be omitted unless you know what you are doing):

+  DateTime.add_parser(:mine, '%Z %m~%Y~%d %S`%M`%H')
 
 === Modifying the Order of Parsers Types
 
 You can change the order in which parsers types are tried by using the
 use_parsers class method, which takes multiple arguments specifying the order
