Overview
The Parts format specifies how phonemes should be expanded into multi-state biphone categories.

Variables
Variable
 Description
token
 An item name, where an item typically represents a phoneme.
clusterName
 A cluster name identifes a group of tokens.  This group of tokens can then be represented by clusterName in a context description.
metaClusterName A cluster name identifes a group of tokens and/or clusters.  This meta-cluster name is then used to define all the ways of expanding a token in a left or right context.
state
 A state name associated with a token.  A state name may include a clusterName as a left or right context, as specified in the state specification format.

Description
The Parts format specifies how phonemes should be expanded into multi-state biphone categories.  The parts format is read by the statenet writeCDRules command.
