A text file like:
{
	data: {
		name: "Kneelawk",
		location: [
			1,
			2,
			3
		]
	}
}
would produce an NBT file like:
TAG_Compound(None): 1 entry
{
	TAG_Compound('data'): 2 entries
	{
		TAG_String('name'): 'Kneelawk'
		TAG_List('location'): 3 entries
		{
			TAG_Int(None): 1
			TAG_Int(None): 2
			TAG_Int(None): 3
		}
	}
}

A text file like:
(file
(properties
name=test.nbt
type=compressed
)
(data
{
	data: {
		str: "Hello World!"
	}
}
)
)
would be produced by a compressed NBT file called 'test.nbt' with contents:
TAG_Compound(None): 1 entry
{
	TAG_Compound('data'): 1 entry
	{
		TAG_String('str'): 'Hello World!'
	}
}

A text file like:
(file
(properties
name=r.-1.-2.mca
type=anvil
)
(partition
(properties
x=-41
z=-52
)
(data
{
	data: {
		hello: "World!"
	}
}
)
)
(partition
(properties
x=-41
z=-53
)
(data
{
	data: {
		hello: "Kneelawk!"
	}
}
)
)
)
would be produced by an anvil region file called 'r.-1.-2.mca' that contained the chunks at (-41,-52) and (-41,-53).
