+was deleted, always write an integrity table. If this option is not specified,

+\fB--soft\fR
+Perform a "soft delete". Specifying this flag overrides the default behavior of
+rebuilding the entire WIM after deleting an image. Instead, only minimal
+changes to correctly remove the image from the WIM will be taken. In
+particular, all streams will be left alone, even if they are no longer
+referenced. This is probably not what you want, because no space will be
+saved by deleting an image in this way.
+.IP ""
+You may use \fB@IMAGEX_PROGNAME@ optimize\fR to delete unreferenced streams from a WIM that
+has had images soft-deleted from it.
