+\fB--compress-slow\fR
+With \fB--recompress\fR: Spend even more time compressing the data in order to
+achieve a higher compression ratio.  Currently, this only has an effect with LZX
+("maximum") compression.  Depending on the data, compressing with this option
+will take around 10 to 15 times longer and produce a LZX-compressed WIM about 1%
+to 5% smaller than one produced with the default LZX compressor.  Depending on
+the data, the resulting WIM may be approximately the same size (typically no
+more than 0.4% different) as a LZX-compressed WIM produced by WIMGAPI.
