+\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
+specified.
+.TP
+\fB--pipable\fR
+Rebuild the WIM so that it can be applied fully sequentially, including from a
+pipe. See \fB@IMAGEX_PROGNAME@ capture\fR(1) for more details about creating
+pipable WIMs. By default, when neither \fB--pipable\fR or \fB--not-pipable\fR
+is specified, the rebuilt WIM will be pipable if and only if it was already
+pipable.
+.TP
+\fB--not-pipable\fR
+Rebuild the WIM in the non-pipable format. (This is the default if
+\fIWIMFILE\fR is not pipable.)
