+ * TCL_TOKEN_WORD -		The token describes one word of a command,
+ *				from the first non-blank character of the word
+ *				(which may be " or {) up to but not including
+ *				the space, semicolon, or bracket that
+ *				terminates the word. NumComponents counts the
+ *				total number of sub-tokens that make up the
+ *				word. This includes, for example, sub-tokens
+ *				of TCL_TOKEN_VARIABLE tokens.
+ * TCL_TOKEN_SIMPLE_WORD -	This token is just like TCL_TOKEN_WORD except
+ *				that the word is guaranteed to consist of a
+ *				single TCL_TOKEN_TEXT sub-token.
+ * TCL_TOKEN_TEXT -		The token describes a range of literal text
+ *				that is part of a word. NumComponents is
+ *				always 0.
+ * TCL_TOKEN_BS -		The token describes a backslash sequence that
+ *				must be collapsed. NumComponents is always 0.
+ * TCL_TOKEN_COMMAND -		The token describes a command whose result
+ *				must be substituted into the word. The token
+ *				includes the enclosing brackets. NumComponents
+ *				is always 0.
+ * TCL_TOKEN_VARIABLE -		The token describes a variable substitution,
+ *				including the dollar sign, variable name, and
+ *				array index (if there is one) up through the
+ *				right parentheses. NumComponents tells how
+ *				many additional tokens follow to represent the
+ *				variable name. The first token will be a
+ *				TCL_TOKEN_TEXT token that describes the
+ *				variable name. If the variable is an array
+ *				reference then there will be one or more
+ *				additional tokens, of type TCL_TOKEN_TEXT,
+ *				TCL_TOKEN_BS, TCL_TOKEN_COMMAND, and
+ *				TCL_TOKEN_VARIABLE, that describe the array
+ *				index; numComponents counts the total number
+ *				of nested tokens that make up the variable
+ *				reference, including sub-tokens of
+ *				TCL_TOKEN_VARIABLE tokens.
+ * TCL_TOKEN_SUB_EXPR -		The token describes one subexpression of an
+ *				expression, from the first non-blank character
+ *				of the subexpression up to but not including
+ *				the space, brace, or bracket that terminates
+ *				the subexpression. NumComponents counts the
+ *				total number of following subtokens that make
+ *				up the subexpression; this includes all
+ *				subtokens for any nested TCL_TOKEN_SUB_EXPR
+ *				tokens. For example, a numeric value used as a
+ *				primitive operand is described by a
+ *				TCL_TOKEN_SUB_EXPR token followed by a
+ *				TCL_TOKEN_TEXT token. A binary subexpression
+ *				is described by a TCL_TOKEN_SUB_EXPR token
+ *				followed by the TCL_TOKEN_OPERATOR token for
+ *				the operator, then TCL_TOKEN_SUB_EXPR tokens
+ *				for the left then the right operands.
+ * TCL_TOKEN_OPERATOR -		The token describes one expression operator.
+ *				An operator might be the name of a math
+ *				function such as "abs". A TCL_TOKEN_OPERATOR
+ *				token is always preceded by one
+ *				TCL_TOKEN_SUB_EXPR token for the operator's
+ *				subexpression, and is followed by zero or more
+ *				TCL_TOKEN_SUB_EXPR tokens for the operator's
+ *				operands. NumComponents is always 0.
+ * TCL_TOKEN_EXPAND_WORD -	This token is just like TCL_TOKEN_WORD except
+ *				that it marks a word that began with the
+ *				literal character prefix "{*}". This word is
+ *				marked to be expanded - that is, broken into
+ *				words after substitution is complete.
