The item \"Set pipe log address\" pops up a file tree browser window
which asks for the target of pipe logging . Address \"-\" means
standard error. Else it must not yet exist or be a writable data file.
"
The item \"Execute command script\" executes the commands in a script
file that should stem from \"Log command script\".
At least it must begin by this line:
# xorriso-tcltk command log script
Be aware that xorriso will slavishly execute those commands. Better check
in advance whether the content of the script file is what you expect.
See man xorriso for the meaning of the commands.
The \"Allow extract to disk\" switch controls whether commands like -extract
are allowed in command scripts. If disabled, then command -osirrox is used
to temporarily block those commands (unless the script ublocks itself, which
would be nasty behavior).
The item \"Permanently ban extraction\" disables -extract irrevocably for
scripts and GUI alike."
