 .SH SYNOPSIS
@@ -33,11 +33,33 @@ 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).

-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.
+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=\fImaximum\fR (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.
+.IP ""
+\fITYPE\fR may also be "recovery" (or "LZMS"); however, this will result in
+reduced compatibility.  See the documentation for this option to
+\fB@IMAGEX_PROGNAME@ capture\fR (1) for more details.
+.TP
+\fB--chunk-size\fR=\fISIZE\fR
+Set the WIM compression chunk size to \fISIZE\fR.  See the documentation for
+this option to \fB@IMAGEX_PROGNAME@ capture\fR (1) for more details.
+.TP
+\fB--pack-streams\fR
+Create a "solid" archive that compresses multiple files together.  This can
+result in a higher compression ratio, but has disadvantages such as reduced
+compatibility; see the documentation for this option to
+\fB@IMAGEX_PROGNAME@-capture\fR (1) for more details.
