 .SH NAME
-imagex-optimize \- Optimize a WIM archive
-
+@IMAGEX_PROGNAME@-optimize \- Optimize a WIM archive
 .SH SYNOPSIS
-\fBimagex optimize\fR \fIWIMFILE\fR [--check]
-
+\fB@IMAGEX_PROGNAME@ optimize\fR \fIWIMFILE\fR [--check] [--recompress]
 .SH DESCRIPTION
-.PP
-\fBimagex optimize\fR will rebuild the stand-alone WIM \fIWIMFILE\fR.  The new
+\fB@IMAGEX_PROGNAME@ optimize\fR will rebuild the stand-alone WIM \fIWIMFILE\fR.  The new
 WIM is written to a temporary file, and it is renamed to the original file when
 it's ready.  This action will remove any holes that have been left as a result
 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
 (although most cannot).

 .SH OPTIONS
 .TP 6
+\fB--check\fR
 When reading \fIWIMFILE\fR, verify its integrity if the integrity table is
-present; include an integrity table in the optimized WIM.  If this option is not
-specified and \fIWIMFILE\fR, no integrity table is included in the optimized
-WIM, even if there was one before.

+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.
+.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.
