+\fB--rebuild\fR
+For \fBimagex append\fR: rebuild the entire WIM rather than appending the new
+data to the end of it. Rebuilding the WIM is slower, but will save a little bit
+of space that would otherwise be left as a hole in the WIM. Also see \fBimagex

Specify a string to use in the <FLAGS> element of the XML data for the new

stream chunk size of 32768. The only WIMs I've seen that are different from
this are some pre-Vista WIMs that had a different version number.
+Unless --rebuild is specified, aborting an \fBimagex append\fR command mid-way
+through has a small chance of corrupting the WIM file. However, a precaution is
+taken against this, so it should be very unlikely. In the event of an aborted
+\fBimagex append\fR, \fBimagex optimize\fR may be run to remove extra data that
+may have been partially appended to the physical WIM file but not yet
+incorporated into the structure of the WIM.
