IntroFoundation (3402 words)
	The Foundation Kit includes the root object class, classes representing basic data types such as strings and byte arrays, and collections of other objects, and classes representing system information such as dates and communication ports between applications.
	The Foundation Kit introduces several paradigms to avoid confusion in common situations, and to introduce a level of consistency across class hierarchies.
	The Foundation Kit's ownership policy limits itself to the question of when you have to dispose of an object; it doesn't specify that any object received in a method must remain valid throughout that method's scope.

Duramax 10 x 13 Woodbridge Vinyl Storage Shed + Foundation Kit & Free Skylight Kit (1722 words)
	One box is an 10x8 shed, a second box is a foundation kit for the 10x8 shed, and boxes three and four are shed extension kits.
	The reason why only a foundation kit is provided for the 10x8 shed is because each extension kit includes a foundation for this portion of the shed.
	In addition to the foundation kit, you can also purchase an optional window kit which can be installed on a side or back wall of the shed.
