+\fB--check\fR
+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.
+.TP
+\fB--nocheck\fR
+Neither verify the integrity of \fIWIMFILE\fR using the integrity table, nor
+include an integrity table in the rebuilt WIM file.
+.TP
+\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).
+.IP ""
+Note: as mentioned in the README, wimlib generally provides a slightly better
+XPRESS compression ratio than Microsoft's software, while it generally provides
+a slightly worse LZX compression ratio than Microsoft's software. So, you may
+not want to specify \fB--recompress\fR when optimizing a LZX-compressed WIM
+created on Windows with Microsoft's ImageX.
+.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.)
