.SH NAME
@IMAGEX_PROGNAME@-optimize \- Optimize a WIM archive
.SH SYNOPSIS
not want to specify \fB--recompress\fR when optimizing a LZX-compressed WIM
created on Windows with Microsoft's ImageX.
.TP
+\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.
+.TP
\fB--threads\fR=\fINUM_THREADS\fR
Number of threads to use for compressing data. Default: autodetect (number of
processors). This parameter is only meaningful when \fB--recompress\fR is also
