 \fB--recompress\fR
 Recompress all compressed streams in \fIWIMFILE\fR when rebuilding it.  This
-will increase the time needed to rebuild the WIM,unless the WIM is uncompressed,
-but it may result in a better compression ratio if wimlib can do a better job
-than the program that wrote the original file.  A side effect of this 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

+not want to specify \fB--recompress\fR when optimizing a LZX-compressed WIM
