+\fB\-assess_indev_features\fR "plain"|"cmd"|"as_mkisofs"|"replay"
+Inspect the filesystem on \-indev for the presence of Rock Ridge, Joliet, or
+ISO 9660:1999, and for traces of other write options which seem to have been
+used when the filesystem was created.
+.br
+Note that this command does not detect and report a possibly present HFS+ tree.
+.br
+Mode "cmd" lists xorriso commands which would activate the detected settings.
+.br
+Mode "as_mkisofs" lists options of the \-as mkisofs emulation, which would
+activate those of the detected settings which are not default.
+.br
+Mode "replay" performs the commands which get listed by mode "cmd".
+.br
+Mode "plain" lists after a "Indev feature: " header name\-value pairs as
+delivered by libisofs function iso_read_image_feature_named(). See libisofs.h.
+The other modes derive their output from this list. I.e. the sequence of
+commands from "cmd" follows the sequence of "plain".
+.br
+Not leading to "cmd" lines are:
+.br
+"size=" tells the number of 2048 byte blocks of the filesystem.
+.br
+"eltorito=1" tells that El Torito boot equipment was detected.
+.br
+"tree_loaded=" tells which tree was loaded by \-indev:
+.br
+  0 = ISO 9660 , 1 = Joliet , 2 = ISO 9660:1999
+.br
+"tree_loaded_text=" tells the same by name: "ISO9660", "Joliet", "ISO9660:1999"
+.br
+"rr_loaded=1" tells that Rock Ridge information was loaded with the tree.
+.br
+"aaip=1" tells that AAIP information was detected (ACL, xattr, MD5, ...).
+.br
+"relaxed_vol_atts=1" tells that the volume attributes like \-volid or
+\-preparer_id bear characters outside the restricted character sets which are
+specified for them by ECMA\-119.
+.br
+"rrip_1_10_px_ino=1" tells that with Rock Ridge 1.10 a PX entry was found which
+looks like from Rock Ridge 1.12.
