+	@brief Codeset flags that determine how the codebook is used for encoding
+
+	The codeset flags determine how the codebook in the codeset is used to
+	compute the tables for encoding coefficient magnitudes and runs of zeros.
+
+	The companding curve is applied to the quantized coefficients before the
+	values are entropy coded to fit the coefficient magnitudes into the range
+	of magnitudes provided by the codebook.  The companding curve is applied
+	when the encoding table for coefficient magnitudes is computed.
