+of those has to be present:
+.TP
+\fB\-\-list\fR, \fB\-l\fR <path>
+Produce a directory listing similar to \fBls \-l\fR for a given path in
+the SquashFS image.
+.TP
+\fB\-\-cat\fR, \fB\-c\fR <path>
+If the specified path is a regular file in the image, extract it and dump
+its contents to stdout.
+.TP
+\fB\-\-unpack\-path\fR, \fB\-u\fR <path>

+Change permission flags of unpacked files to
+those store in the SquashFS image.
+.TP
+\fB\-\-chown\fR, \fB\-O\fR
