-\fB--compress-slow
-For LZX compression only: spend even more time compressing the data in order to
-achieve a more optimal compression ratio. This will make compression about
-twice as slow and will increase the compression ratio by maybe 1%, if you're
-lucky.
+\fB--recompress-slow\fR, \fB--compress-slow\fR
+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.
