 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.

 \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).
