+EXPERIMENTAL, Windows-only: compress the extracted files using System
+Compression, when possible. This only works on either Windows 10 or later, or
+on an older Windows to which Microsoft's wofadk.sys driver has been added.
+Several different compression formats may be used with System Compression, and
+one must be specified as \fIFORMAT\fR. The choices are: xpress4k, xpress8k,
+xpress16k, and lzx.

+Exclusions are handled in the same way as with the \fB--wimboot\fR option.
+That is: if it exists, the [PrepopulateList] section of the file
+\\Windows\\System32\\WimBootCompress.ini in the WIM image will be read, and
+files matching any of the patterns in this section will not be compressed.
