		+	== Name Tables ==
		+
		+	Name tables are pools of strings used by multiple different JSYSTEM files, under the class name JUTNameTab. They collect all strings used in a chunk or section so that multiple references to the same string can be referenced by an index into the name table. A name table is laid out like this:
		+
		+	{\| class="wikitable"
		+	\|-
		+	! Offset !! Type !! Name !! Description
		+	\|-
		+	\| <center>0x00</center> \|\| int \|\| Name Count \|\| The number of names in this Name Table.
		+	\|-
		+	\| <center>0x04</center> \|\| JUTNameTabEntry[Count] \|\| Entries \|\| A variable-length set of entries.
		+	\|}
		+
		+	Each entry consists of the following.
		+
		+	{\| class="wikitable"
		+	\|-
		+	! Offset !! Type !! Name !! Description
		+	\|-
		+	\| <center>0x00</center> \|\| short \|\| Hash Code \|\| A hash code of the string for fast lookup.
		+	\|-
		+	\| <center>0x02</center> \|\| short \|\| String Offset \|\| An offset, relative to the start of the name table, containing the string contents followed by a NUL byte.
		+	\|}
