Normally any number of leading dashes is ignored with command words and
inner dashes are interpreted as underscores.

.B Execution order of program arguments:
.PP
By default the program arguments of a xorriso run are interpreted as a
sequence of commands which get performed exactly in the given order.
This requires the user to write commands for desired settings before the
commands which shall be influenced by those settings.
.br
Many other programs allow to hand over options as program arguments
in an arbitrary sequence and perform settings and actions in a sequence
of their own discretion. xorriso provides an option to enable such a behavior
at the cost of losing freedom of expression.
.TP
\fB\-x\fR
Enable automatic sorting of program arguments to a sequence that most likely
makes some sense. This command may be given at any position among the commands
which are handed over as program arguments.

It works only if it is given as program argument. I.e. not
in startup files. not with \-options_from_file, not in dialog mode.
.TP
\fB\-list_arg_sorting\fR
List all xorriso commands in the order which applies if option \-x is in effect.

This list may also be helpful without \-x, for a user who ponders over the
sequence in which to put commands. Deviations from the sorting order may
well make sense, though.
