-It is safe to abort an \fBwimlib-imagex append\fR command partway through;
-however, after doing this, it is recommended to run \fBwimlib-imagex

-not yet incorporated into the structure of the WIM, unless the WIM was being
-fully rebuilt (e.g. with \fB--rebuild\fR), in which case you should delete the
