To operate on the resulting delta WIM using other commands such as
\fB@IMAGEX_PROGNAME@ apply\fR, you must specify the delta WIM as the WIM file to
operate on, but also reference the base WIM using the \fB--ref\fR option.

+Note: unlike "pipable" WIMs (created with the \fB--pipable\fR option), "delta"

+Additional note: \fB@IMAGEX_PROGNAME@\fR is generalized enough that you can in
