 Also, unlike imagex.exe, it is legal to delete all the images from a WIM and
 have a WIM with 0 images, although such a file wouldn't be very useful.

+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 almost no space will be
+saved by deleting an image in this way.

+You may use \fBimagex optimize\fR to delete unreferenced streams from a WIM that
+has had images soft-deleted from it.
