+.SH NAME
+wimlib-imagex-optimize \- Optimize a WIM archive
+.SH SYNOPSIS
+\fBwimlib-imagex optimize\fR \fIWIMFILE\fR [\fIOPTION\fR...]
+.SH DESCRIPTION
+\fBwimlib-imagex 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.
+.PP
+By default, compressed data will be re-used, and not recompressed. Use the
+\fB--recompress\fR or \fB--compress\fR=\fITYPE\fR[:\fILEVEL\fR] option to
+request recompression.
+.PP
+This command is also available as simply \fBwimoptimize\fR if the appropriate
+hard link or batch file has been installed.
+.SH OPTIONS
+.TP 6
+\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 greatly increase the time needed to rebuild the WIM file, but it may result
+in a better compression ratio if wimlib can do a better job than the program
+that wrote the original file.
+.TP
+\fB--compress\fR=\fITYPE\fR[:\fILEVEL\fR]
+Recompress the WIM file using the specified compression type, and optionally the
+specified compression level for that compression type. This implies
+\fB--recompress\fR.
+.IP ""
+See the documentation for this option to \fBwimlib-imagex 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 \fBwimlib-imagex capture\fR (1) for more details.
+.TP
+\fB--solid\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 \fBwimlib-imagex
+capture\fR (1) for more details.
+.TP
+\fB--solid-chunk-size\fR=\fISIZE\fR
+Like \fB--chunk-size\fR, but set the chunk size used in solid blocks. See the
+documentation for this option to \fBwimlib-imagex capture\fR (1) for more
+details.
+.TP
+\fB--solid-compress\fR=\fITYPE\fR[:\fILEVEL\fR]
+Like \fB--compress\fR, but set the compression type used in solid blocks. See
+the documentation for this option to \fBwimlib-imagex capture\fR (1) for
+more details.
+.TP
+\fB--threads\fR=\fINUM_THREADS\fR
+Number of threads to use for compressing data. Default: autodetect (number of
+processors). This parameter only has an effect when data recompression is
+requested.
+.TP
+\fB--pipable\fR
+Rebuild the WIM so that it can be applied fully sequentially, including from a
+pipe. See \fBwimlib-imagex 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.)
+.SH NOTES
+\fBwimlib-imagex optimize\fR does not support split WIMs.
+.PP
+\fBwimlib-imagex optimize\fR is roughly equivalent to:
+.RS
+.PP
+\fBwimlib-imagex export\fR \fIWIMFILE\fR all tmp.wim && mv tmp.wim \fIWIMFILE\fR
+.RE
+.PP
+.SH EXAMPLES
+Rebuild the WIM file 'install.wim':
+.RS
+.PP
+wimoptimize install.wim
+.RE
+.PP
+Rebuild and recompress the WIM file 'install.wim':
+.RS
+.PP
+wimoptimize install.wim --recompress
+.RE
+.PP
+Rebuild and recompress the WIM file 'install.wim', using "maximum" (LZX)
+compression at a higher-than-default compression level. The compression chunk
+size remains unchanged. This command will be slow, but it might be useful for
+optimizing files for distribution. See the COMPRESSION RATIO section of the
+README file for some benchmark results.
+.RS

+wimoptimize install.wim --compress=maximum:100
