.SH NAME
wimlib-imagex-optimize \- Optimize a WIM archive
.SH SYNOPSIS
\fB--not-pipable\fR
Rebuild the WIM in the non-pipable format. (This is the default if
\fIWIMFILE\fR is not pipable.)
+.TP
+\fB--unsafe-compact\fR
+Compact the WIM file in-place, without using a temporary file. Existing
+resources are shifted down to fill holes and new resources are appended as
+needed. The WIM file is truncated to its final size, which may shrink the
+on-disk file. THIS OPERATION CANNOT BE SAFELY INTERRUPTED! If the operation is
+interrupted, then the WIM file will be corrupted, and it may be impossible (or
+at least very difficult) to recover any data from it. Users of this option are
+expected to know what they are doing and assume responsibility for any data
+corruption that may result.
.SH NOTES
\fBwimlib-imagex optimize\fR does not support split WIMs.

-Rebuild and recompress the WIM file 'install.wim', using "maximum" (LZX)
+Rebuild and recompress the WIM file 'install.wim', using LZX ("maximum")
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
