+In default mode "off", iso_rr files lose their inode numbers at image load
+time. Each iso_rr file object which has no inode number at image generation
+time will get a new unique inode number if -compliance is set to -new_rr.
+.br
+Mode "on" preserves eventual inode numbers from the loaded image.
+When committing a session it searches for families of iso_rr files
+which stem from the same disk file, have identical content and have
+identical properties. The family members all get the same inode number.
+.br
+Mode "on" automatically enables \fB\-compliance new_rr\fR. This may be
+overridden by a following -compliance old_rr . In this case the resulting
+image will violate the RRIP-1.10 specs for entry PX in the same way as
+mkisofs does.
