-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.

+.IP ""
+Note: as of wimlib v1.5.3, wimlib's LZX compressor usually achieves the same or
+better compression than Microsoft's, but is slightly slower.
+.TP
+\fB--recompress-slow\fR, \fB--compress-slow\fR
+Spend even more time compressing the data in order to achieve a more optimal
+compression ratio. 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. This option implies \fB--recompress\fR and
+\fB--compress\fR="maximum" (recompress using LZX compression).
+.TP
+\fB--compress\fR=\fITYPE\fR
+Recompress the WIM file using the specified compression type. \fITYPE\fR may be
+"none", "fast", or "maximum". This implies \fB--recompress\fR.
+.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.)
