-update_r is also a convenient compromise between -add addressing and -cpr

inherited from cp -r behavior. Its syntax resembles cp, though.

.TP
\fB\-not_mgt\fR code[:code[...]]
Control the behavior of the exclusion lists.
.br
Exclusion processing happens before disk_paths get mapped to the ISO image
and before disk files get compared with image files.
The absolute disk path of the source is matched against the -not_paths list.
The leafname of the disk path is matched against the patterns in the -not_leaf
list. If a match is detected then the disk path will not be regarded as an
existing file and not be added to the ISO image.
.br
Several codes are defined.
The _on/_off settings persist until they are revoked by their_off/_on
counterparts.
.br
"erase" empties the lists which were accumulated by -not_paths and -not_leaf.
.br
"reset" is like "erase" but also re-installs default behavior.
.br
"off" disables exclusion processing temporarily without invalidating
the lists and settings.
.br
"on" re-enables exclusion processing.
.br
"param_off" applies exclusion processing only to paths below disk_path
parameter of commands. I.e. explicitely given disk_paths are exempted
from exclusion processing.
.br
"param_on" applies exclusion processing to command parameters as well as
to files below such parameters.
.br
"subtree_off" with "param_on" excludes parameter paths only if they
match a -not_paths item exactly.
.br
"subtree_on" additionally excludes parameter paths which lead to a file
address below any -not_paths item.
.br
"ignore_off" treats excluded disk files as if they were missing. I.e. they
get reported with -compare and deleted from the image with -update.
.br
"ignore_on" keeps excluded files out of -compare or -update activities.
.TP
\fB\-not_paths\fR disk_path [***]
Add the given paths to the list of excluded absolute disk paths. If a given
path is relative, then the current -cdx is prepended to form an absolute path.
Eventual pattern matching happens at definition time and not when exclusion
checks are made.
.br
(Do not forget to end the list of disk_paths by "--")
.TP
\fB\-not_leaf\fR pattern
Add a single shell parser style pattern to the list of exclusions for
disk leafnames. These patterns are evaluated when the exclusion checks are
made.
.TP
\fB\-follow\fR occasion[:occasion[...]]
Enable or disable resolution of symbolic links and mountpoints under
disk_paths. This applies to actions -add, -du*x, -ls*x, -findx,
