[Handel] [ANNOUNCE] Handel 0.30 Released

[Christopher H. Laco]

Back by popular demand, I present to thee Handel 0.30. It includes the
following coding mistakes:

0.30 Fri Dec 23 22:52:23 2005

    * Constraint constraint_price now accepts 0 as a valid value

    * Added order_class to Handel::Checkout to allow Checkout->order to
create subclassed versions of Order objects

    * Added cart_class to Handel::Order to allow Order->new to create
subclassed versions of Cart objects

    * Added copy_cart/copy_cart_items in Handel::Order so subclasses can
customize order creation from custom carts

    * When copying cart items into a new order, only columns in
Handel::Cart::Item instead of all columns found
