 of appending images, so the new WIM may be slightly smaller than the old WIM.
 In addition, some errors in the original WIM may be fixed by re-writing it

+This command is also available as simply \fBwimoptimize\fR if the appropriate

 .SH OPTIONS

 \fB--check\fR
-When reading \fIWIMFILE\fR, verify its integrity if the integrity table is
-present; in addition, include an integrity table in the optimized WIM.  If this
-option is not specified, no integrity table is included in the optimized WIM,
-even if there was one in the original WIM.
+When reading \fIWIMFILE\fR, verify its integrity if an integrity table is
+present.  In addition, include an integrity table in the optimized WIM.  If this
+option is not specified, by default the integrity table (if present) is not
+checked, and an integrity table is included in the rebuilt WIM if and only if
+one was present in the original WIM.

+Neither verify the integrity of \fIWIMFILE\fR using the integrity table, nor

+\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.

+\fB--not-pipable\fR
+Rebuild the WIM in the non-pipable format.  (This is the default if
+\fIWIMFILE\fR is not pipable.)

 \fB@IMAGEX_PROGNAME@ optimize\fR does not support split WIMs.
