Set the threshold for events to abort the program.
Events are classified by severity :
.br
"NEVER", "ABORT", "FATAL", "SORRY", "WARNING",
"HINT", "NOTE", "UPDATE", "DEBUG", "ALL"
"NEVER", "ABORT", "FATAL", "FAILURE" , "SORRY",
"WARNING", "HINT", "NOTE", "UPDATE", "DEBUG", "ALL"
.br
Severities "NEVER" and "ALL" do not occur but mark the extreme
ends of this potentially expandable range.

\fB\-reassure\fR "on"|"tree"|"off"
If "on" then ask the user for "y" or "n"
before deleting or overwriting any file in the ISO image.
If "on" then ask the user for "y" or "n":
.br
before deleting or overwriting any file in the ISO image,
.br
before rolling back pending image changes,
.br
before committing image changes to media,
.br
before ending the program.
.br
With setting "tree" the reassuring prompt will appear for an eventual
directory only once and not for each file in its whole subtree.
Setting "off" silently kills any kind of image file object.
