 is that every stream in the original WIM will be checksummed, so this can help
 verify that the WIM is intact (equivalent to applying all the images from it).

-Note: as mentioned in the README, wimlib generally provides a slightly better
-XPRESS compression ratio than Microsoft's software, while it generally provides
-a slightly worse LZX compression ratio than Microsoft's software.  So, you may
-not want to specify \fB--recompress\fR when optimizing a LZX-compressed WIM
-created on Windows with Microsoft's ImageX.
+Note: as of wimlib v1.5.3, wimlib's LZX compressor usually achieves the same or
+better compression than Microsoft's, but is slightly slower.

-\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.

+Spend even more time compressing the data in order to achieve a more optimal
+compression ratio.  This only affects LZX-compressed WIM files.  Compared to the
+default \fB--recompress\fR, this will make compression about twice as slow and
+will increase the compression ratio by maybe 1%, depending on the data.
