+ (description
+ "JBIG2 is designed for lossy or lossless encoding of 'bilevel'
+(1-bit monochrome) images at moderately high resolution, and in
+particular scanned paper documents. In this domain it is very
+efficient, offering compression ratios on the order of 100:1.
+
+This is a decoder only implementation, and currently is in the alpha
+stage, meaning it doesn't completely work yet. However, it is
+maintaining parity with available encoders, so it is useful for real
+work.")
